Man I’m so thankful for this rebuild I’ve done a couple 4L60 rebuilds for myself never did anything to valve body or pump I’m now building a stage 3 700R4 85 year model and unfortunately I got ahead of myself pulling stuff apart not labeling it. Stupid I know but with this video I have successfully rebuilt my pump and valve body with little to no worry. Thanks for this great video
Using your videos and transmission bench videos I've learned how to rebuild and identify parts in a transmission. I've rebuilt 5 so far and about to do number 6 all the last five have been great. thank you for the knowledge and much love!
Well done Hiram. I like the way you did your video, it is high quality image and sound and you have a very good grasp of what you are doing, confident and efficient.
Very nice video. I may get a TransGo shift kit for the next trans I do. Since I'm trying to learn to do transmission repair professionally and the way TransGo writes their instructions, it may very well wind up being that for me and others like myself trying to learn this trade, the instructions for the TransGo shift kits could be the most valuable part of the kit.
Yeah, I think they're great too even though I've personally never used one, at least not yet. Like I said, the next trans I do, I plan on using a TransGo shift kit. I guess I should clarify what I said about the instructions being the most valuable part of the kit for someone such as myself, trying to learn professional transmission repair. The way I look at it, the instructions are valuable, not just to get a quick turnaround and prevent comebacks on whatever unit you happen to be working on, but rather to study them and to figure out how and why the fixes in those kits work. I think understanding how and why those fixes work could enhance ones understanding of transmission operation and improve diagnosis for all transmissions, not just the unit that specific kit is designed to work with. It's a win-win to me.
Just a question regarding a step you skipped in the video.... In the kit, it mentions grinding the 2nd land on the Pressure Regulator Valve (PRV) and instead never even removed it before dropping green spring. Was that just because of the difficulty in its removal face up? Would you recommend doing so otherwise? I understand it provides more constant lubrication. Thanks for everything. I do see you have many ppl asking for your advice and questions, I wish I didn't add to that list too.
Ah... I see. I deal with mostly MUCH older vehicles, and I didn't know that about the PRV. I haven't come across too many photos in doing my research either, which is why I personally appreciate your videos and help/replies that much more. Pictures are worth gold, videos are priceless. Gracias por todo otravez!!
Good video boss.. helped me out alot.. I'm workin on one rite now.. I put the valve body link on backwards.. I wouldn't shift from park.. but I watched your video and I finally figured it out.. haha.. thanks man.. I need that kit.. where can I get it
Really like your video. A lot of info there. You mention that "It's very common that after you get done with one of these that it will not want to upshift into 4th". What's the fix ? Thanks
You let it this install look like it is piece of cake. I am in the middle of installing a TransGo TF2 kit on a Torqflite 727 valve body. I'm gonna need some guidance or this vb will only be serving as a bookstand...
So replacing that big red spring thats behind the valve is impossible if you dont take the whole body off ? Or can you just take off the kick down throttle assembly (z) and remove the outside roll-pin to replace that red spring?
I noticed that you did not grid the first landing off of the pressure regulator valve. The instructions indicate to do this. Is it ok to skip this step?
Great Job Hiram. My only question; is there a big difference between an 84 and a 89? I have a 89 model that will be replacing a 84 model that had a bad case. It is a fresh rebuild. had a few broken parts that were replaced. It is not releasing from forward. changes gears off the ground. No 4th. Will not drive the wheels backwarrds. You can feel it going into R but the wheels dont move. Initially they moved backwards. Once I went into D it has styed there. N,OD,D,2,1 all move forward and are limited by their location. Of course the local shop cant think of it without the trans in front of them. Will this kit help me? Or should I get the full transgo 700 Kit? Thanks in Advance.
Hello Hiram, I have a question concerning the servo modification. Is the modifications that are made to the servo take the place of replacing it with a corvette assembly, or is it best to use a corvette servo? Also, is a corvette boost valve needed or recommended for the pump?
Please help! I rebuilt my 700 following every video you've made on it. Including the transgo kit. Now the line pressure is WAY too low! (Not that I had the ability to test it before.) My issues are with 1st gear. In the D position the trans is actually in 2nd to start, but if I manually shift to 1st it will start in 1st and shift to 2nd at about 7mph. Also if I am going down a steep hill and need 1st to slow me down, it won't hold there at all. ( I damn near killed myself on a very steep, winding mountain road with my breaks smoking and loss of break pressure.) The one mistake I think I made is drilling larger holes in the seperater plate in the locations you recommended, too big. I didn't check the diameter with calipers. I don't know the purpose of drilling those holes bigger so I don't know if that is the issue. This is a mountain truck and I need 1st gear working correctly. Again, please, your advice is greatly appreciated!
Hiram how you doin? Have a quick question for you if you could help me. I have done up a 700r4 and put it in a 77 vette all is good except shift points and using the Governor out of the T350 as figured it was good for ratios etc. Not working the way it was in the T350 with good low speed shifts, rather than going through the weights springs process I was wondering if changing the TV valve spring to a lighter/shorter one ( I have 3 different spare ones) would bring the shift points down across the range. When I built the trans I used the longest one which was from another trans. I have one from a transgo shift kit and others from a V6 and V8 trans. Hope you can help. Once again love your work.
Hi Hiram thanks for the reply,I did a swap to a spring of the same length but a thinner coil dia - .05 less from memory and it took the points down to where I wanted them for highway work, I used a standard V6 governor and the lighter spring worked excellent. I also had to lengthen the cable out 1 clip past standard adjustment to ensure proper pressure rise from idle. I took a lot of care with the cable mounting and arc of travel. if anything the distance from centre pivot is maybe on the upper limit but OK, maybe why I had to step the cable out one notch.
when the the throttle is at rest how far out does the TV plunger sit? Ive got an issue with my trans and the manufacturer has advised that the valve may be sticking from breaking in the trans. When ive removed the pan ive noticed that the plunger is sticking out about 5 groves and there is a noticable space before the lever. if i pull the plunger it come outs about 1 move groove and touched the lever. The plunger will push all the way in and you can feel the spring compression. When release it goes back to about 5 grooves and the last grove before it touches the level has no spring pressure and is loose. Is this normal? what moves the tv valve back, oil pressure? would this plunger move back fully when in operation?
Hiram, I have a question. I already rebuilt my '93 700R4 (MD8 case) and used the Transgo 700 2&3 kit. All is well, shifts strong, good lock up, good pressures, etc., except that from time to time, I don't get 4th gear. Which parts of the 700 JR kit corrects the lack/loss of 4th gear. The 2 & 3 kit already had a pump valve (looks like the toughest part while on one's back in the garage), and I wonder if some of the JR kit parts are already in my transmission or were a part of the 2 & 3 kit. Thanks in advance.
Great video!!! I’m installing the transgo shift kit on a 2004r, when I install the tv boost valve it went it real stiff . Now I put in the new snap ring , which is seated . But pushing on the boost valve with a screwdriver I get very minimal movement Is this normal? Thanks in advance !!!
I am going to install this kit and ordered corvette servo's. What does this alter in the kit or just follow the instructions? My corvette servo's came with 2 white springs.
Hola Hiram! Un cordial saludo desde Venezuela! Fan #1!!! Estabas pariendo para meter la Válvula en la Bomba... Saludos! Otra cosa... ¿Cuando me ayudas con la Prueba de Banco para el Bloque de Solenoides A604? ¿Como se cuando están en correcto funcionamiento?
On the 3-4 accumulator witch of the two stoch springs go back im there I noticed that there was two different sizes and put the larger of the two in there but my trans is not shifting in to over drive now I installed transgo shift kit and did full rebuild
I had a rebuilt(approx 10k miles) 700r4 but it sat for like 4+ yrs, but it had oil, got around to replace the filter and atf with new tv cable but now it won't shift out of first but it has reverse. Trans. Shop sold me a universal tv cable could that be the issue (not calibrated right)?
Hello quick question I was wondering on the first step where it says grind this land flush all the way around it's not fussy ... I saw that u didn't grind the PR Valve , does that matter
Is there any issue with installing a correction kit like this on a transmission that has some miles on it ? For example 120,000 miles on the original OEM never been rebuilt transmission that has been serviced via oil and filter changes every 30,000 miles ? Still functions good and had the Corvette servo put on it about mileage 65,000 to improve shift 1 to 2.
hi Hiram the 4 notch on the servo plate can make those notch on and shift kit on 700r4 or 4l60e and what's the benefit on the transmission thanks very good videos
I have a 7ooR4 in my 88 Surburban XL with a 350 TBI(soon to be carb) suddenly my wife was driving it and it lost all power, it was towed to the house, I started it the next day trying to make it do something, you can tell that you've moved the shifter and the vehicle wants to do something but it wont or just barely creeps,it is 6800lbs. Anyway I built the engine but I've never been in a chevy trans only mopar, I love this vehicle and need it back in duty as it is her daily driver, any ideas as to what happened? It like its lost all line pressure or the clutches just went out, there are no leaks,odd noises, nothing,TV cable is functioning properly...Help?
I'm installing this kit on a unit I'm building for a friend. The instructions say to reuse the 3-4 accumulator spring but when I disassembled the transmission I got the two springs mixed up and I don't remember what one came out of what side of the channel plate. Do I use the stiff or soft spring in the case for the 3-4 accumulator? I also have a new channel plate coming because the check balls beat the hell out of the old one. Will the new transgo plate already be drilled with the proper size holes?
+Billybob themechanic Never mind, after I thought about it the kit has you flip the piston and the spring basically taking the spring out of the equation. With it like this the spring is just in there to keep the piston from floating around. I will stick the soft spring in there.
hola hiram acavo de terminar una de estas unaidades 700r4 no ay upshift se quedo solo un firt y reverse que puedo haser me urge areglar esto ya que es de unas personas sercanas
@Dels Transs I can’t answer for Hiram, the this Transgo jr shift can help your 1-2 soft or slide bump upshift. P/N SK 700-Jr-B As long as you don’t have other issues or high miles, parts outside this kit can wear or stick causing the same issue. Check fluid conditions to start, but with pan off, stop and inspect to determine what’s in there. If clean, good to go. If you find dime to quarter size piles of friction material or what looks like metal-flake paint job it may take more. Pump makes pressure to apply a drum or hold a band, but these use a tv cable to adjust actual holding pressures. Less pressure is less engine load and better gas mileage, but bad for holding. This tv cable has to be adjusted right but also free in the VB. You saw valves stick in the video and this will effect shifting. A valve gets pressure on one end but the faster you go, the governor pressure will change. So the valve will move to the side with less total force on it, then a shift will happen, as the last one exhaust and let’s go. During this time pressure pushes on accumulator to delay total pressure, then upshift happens. If tv is adjusted tight at WOT, 1-2 shift valve is free, governor works as it determines when the shift happens. This video did not go into this, but lives in case cover on RR round cover. A valve inside moves as weights push against it. The pressure drops and the shift occurs. If this is only problem, then try the kit. If all are early, fix governor first, otherwise, valves in the valve body will be helped by the kit. Make sure to do updates on the TV valve as well. Blessings!
@@DELTRANIO99 Sorry to be long, I am retired but Hirum is trying to earn a living I am sure. Autos are complicated with a balancing act between gov pressure that drops the faster you go, shift of line pressure pushing against a valve at a certain ratio, plus spring for some adjustment. It is like a "Teeter-Totter SeeSaw" action for balance. Hirum is a good egg, as you can tell by what he shares. Watch all of his videos on the 700r4 + 4L60 and many things are the same on the 4L60e but solenoids for shifting pressure and force motor / pressure control motor - stepper motor, that controls TV pressure. If clean fluid, small amount of debris in pan, go for it. The "Gov" can be service outside rear on passengers side. Check plastic gear for "Apple Coring" or what you may call "Low in the Center" of the plastic driven gear, sold by color to VSS correction. It should not turn when installed and try several locations. Just be careful with vehicle up on rated stands, wheel chocks and solid ground while engine off and out of park, rotate drive-shaft to check gov. It has weights, springs that can be changed to dial in a shift speed. Just write down changes and results BUT only do one change at a time. Best of luck, hope this helps.

Hi, Hiram my name is Mario and Im starting to build transmissions after 15 years of general auto repair. first trans I built about a month ago was out of the 2000 Odyssey and that was a successful build all thanks because I watched and follow directions of one of your videos. this time im trying to build this 700r4 out of a 1987 chevy van g20 and I also watched your video for this one, however when I watched this video to finish installing the valve body I found out that you don't show or mention the location of all the check balls, I looked it up on all data and it only shows thae location of 4 of them but I got 8 ???? so I'm stuck her and cant finish the unit. could you upload a quick video for that ?? thank you.
Hi Hiram, good video I love your work because it is so clear and professional you are a great specialist, Just quick question/s re checkballs, When I pulled the tranny down, it had a large check ball as well as the 1/4" balls, it is a 1990 unit and the ATSG manual, Transgo instructions and you do not mention them for this unit do I just ditch them or install them and if yes, where? I will be checking the separator plate for signs of the location of the checkballs, Are there many different places for the 1990 units or do I work strictly to the ATSG manual for the year?
Thanks Hiram I came across the your video on checkball locations, and have decided to go with the one loose checkball option. What effect does this have on shifting? I have fitted the Transgo jr kit,is that an issue if I leave the other balls out. Keep up the good work! Love it. *****
Hey my 700r4 won't shift out of first. Used to I could get the rpm up high then easily let off the gas and it would shift out but now won't shift out of first at all what do you think the issue could be thanks for your time.
Hiram Gutierrez yes is there supposed to be a self tapping Allen head plug in the case below the one to accumulator piston there was one in my transmission that was part of a modification and I removed it so I'm wondering if I did the right thing I'm trying to put it back to a stock condition
hola hiran con todo respeto...desde vzla...tengo un bendito chevy corsa automatico como hariamos para ensamblar su cuerpo d valvula q me tiene loco y aqui en vzla..sonmuy tramposos y no le solucionan nada auno hay una cas q tiene el manual completo d ese cuerpo dvalvulas d esa caja aw 6040 d corsa??x fa ayudame sobre ello...
@Nick Thomson I am suggesting you look at the RPO code list on the glove box lid for the trans code. But look at the transmission itself to see if the bell housing is split. You need to replace the metal clad tapered rubber front seal, plus get a T50 TORX bit. There are different offsets on crankshafts on certain Vortec engines, so you may need the OEM torque converter and flex plate. I am just saying to be prepared. Hiram does us a favor by just showing us what he does. A service tech gets paid by what we get done and not clock time. So, if he is putting food on the table, he has little time to respond.

With a corvette servo by ac delco does not have 553 or 554 on it should I use the black spring Thanks Hiram
Is there any issue with installing a correction kit like this on a transmission that has some miles on it ? For example 120,000 miles on the original OEM never been rebuilt transmission that has been serviced via oil and filter changes every 30,000 miles ? Still functions good and had the Corvette servo put on it about mileage 65,000 to improve shift 1 to 2.
If everything is in good working order it's safe to say yes, it will improve it.
I don't see why not.

As long as you don’t have other issues or high miles, parts outside this kit can wear or stick causing the same issue. Check fluid conditions to start, but with pan off, stop and inspect to determine what’s in there. If clean, good to go. If you find dime to quarter size piles of friction material or what looks like metal-flake paint job it may take more.
Pump makes pressure to apply a drum or hold a band, but these use a tv cable to adjust actual holding pressures. Less pressure is less engine load and better gas mileage, but bad for holding. This tv cable has to be adjusted right but also free in the VB. You saw valves stick in the video and this will effect shifting. A valve gets pressure on one end but the faster you go, the governor pressure will change. So the valve will move to the side with less total force on it, then a shift will happen, as the last one exhaust and let’s go. During this time pressure pushes on accumulator to delay total pressure, then upshift happens.
If tv is adjusted tight at WOT, 1-2 shift valve is free, governor works as it determines when the shift happens. This video did not go into this, but lives in case cover on RR round cover. A valve inside moves as weights push against it. The pressure drops and the shift occurs. If this is only problem, then try the kit. If all are early, fix governor first, otherwise, valves in the valve body will be helped by the kit. Make sure to do updates on the TV valve as well.
Blessings!
@@deankay4434 Thank you for taking the time explaining this to me
@@DELTRANIO99 Sorry to be long, I am retired but Hirum is trying to earn a living I am sure. Autos are complicated with a balancing act between gov pressure that drops the faster you go, shift of line pressure pushing against a valve at a certain ratio, plus spring for some adjustment. It is like a "Teeter-Totter SeeSaw" action for balance.
Hirum is a good egg, as you can tell by what he shares. Watch all of his videos on the 700r4 + 4L60 and many things are the same on the 4L60e but solenoids for shifting pressure and force motor / pressure control motor - stepper motor, that controls TV pressure.
If clean fluid, small amount of debris in pan, go for it. The "Gov" can be service outside rear on passengers side. Check plastic gear for "Apple Coring" or what you may call "Low in the Center" of the plastic driven gear, sold by color to VSS correction. It should not turn when installed and try several locations. Just be careful with vehicle up on rated stands, wheel chocks and solid ground while engine off and out of park, rotate drive-shaft to check gov. It has weights, springs that can be changed to dial in a shift speed. Just write down changes and results BUT only do one change at a time. Best of luck, hope this helps.

@@deankay4434 Lol Dont be sorry I appreciate your input and taking the time to explain this to me
Hi, Hiram my name is Mario and Im starting to build transmissions after 15 years of general auto repair. first trans I built about a month ago was out of the 2000 Odyssey and that was a successful build all thanks because I watched and follow directions of one of your videos. this time im trying to build this 700r4 out of a 1987 chevy van g20 and I also watched your video for this one, however when I watched this video to finish installing the valve body I found out that you don't show or mention the location of all the check balls, I looked it up on all data and it only shows thae location of 4 of them but I got 8 ???? so I'm stuck her and cant finish the unit. could you upload a quick video for that ?? thank you.
thank you.
Hello Hiram, do you have a video of a 4L30E rebuild that you can share ??
Hi Hiram, good video I love your work because it is so clear and professional you are a great specialist, Just quick question/s re checkballs, When I pulled the tranny down, it had a large check ball as well as the 1/4" balls, it is a 1990 unit and the ATSG manual, Transgo instructions and you do not mention them for this unit do I just ditch them or install them and if yes, where?
I will be checking the separator plate for signs of the location of the checkballs, Are there many different places for the 1990 units or do I work strictly to the ATSG manual for the year?
Thanks Hiram I came across the your video on checkball locations, and have decided to go with the one loose checkball option. What effect does this have on shifting? I have fitted the Transgo jr kit,is that an issue if I leave the other balls out. Keep up the good work! Love it. *****
yes #1
i a 1996 silverado reverse work fine,d 3 2 1 engine reav like its in neutral can i get some feed on what the problem might be 700r4 trans
Is there any reference videos for the 4L30E transmission ?
What happens if you don't put in check ball for auxillary valve body?
You'll have a double bump engagement in 1st and probably burn forward frictions.
Hey my 700r4 won't shift out of first. Used to I could get the rpm up high then easily let off the gas and it would shift out but now won't shift out of first at all what do you think the issue could be thanks for your time.
Logan Moore did you ever figure out what your problem was? I could really use the help right now;)
Logan Moore me too man
Hi..you no grind land flush the pr valve??
Hiram what is the best way to adjust the tv cable i cant set up mine right shift to s
n or shift to late thank u
Ok thanks i going to tried that today
Hiram Gutierrez yes is there supposed to be a self tapping Allen head plug in the case below the one to accumulator piston there was one in my transmission that was part of a modification and I removed it so I'm wondering if I did the right thing I'm trying to put it back to a stock condition
hola hiran con todo respeto...desde vzla...tengo un bendito chevy corsa automatico como hariamos para ensamblar su cuerpo d valvula q me tiene loco y aqui en vzla..sonmuy tramposos y no le solucionan nada auno hay una cas q tiene el manual completo d ese cuerpo dvalvulas d esa caja aw 6040 d corsa??x fa ayudame sobre ello...
Does this transgo kit include the valve body gaskets as well?
Thanks Hiram, great videos too, keep up the good work. SUBSCRIBED
have you done a valve body upgrade on a jatco jr710e transmission
Is this out of a 80's trans am ??
Can I take a transmission out of a 2010 Yukon xl and swap the bell housing that fits my 09 Sierra 1500 and everything be groovy
@Nick Thomson I am suggesting you look at the RPO code list on the glove box lid for the trans code. But look at the transmission itself to see if the bell housing is split. You need to replace the metal clad tapered rubber front seal, plus get a T50 TORX bit. There are different offsets on crankshafts on certain Vortec engines, so you may need the OEM torque converter and flex plate. I am just saying to be prepared.
Hiram does us a favor by just showing us what he does. A service tech gets paid by what we get done and not clock time. So, if he is putting food on the table, he has little time to respond.

Do you still have a link or part # for this kit?
I have a 4L60e 94 model rebuilt it and it want shit out of first gear at all what needs to be done and it's has a trans go stage 2 kit
is the speedo working?
Band was not on the pin inside
i have a 90 700r4 it shifts late and hard i changed spacer plate rework gov still no change
Did u fix ur problem?
