5R55W Transmission Servo Bore Repair - Transmission Repair
HTML-код
- Опубликовано: 4 сен 2024
- This procedure applies to the 5R55W, 5R55S and 5R55N Transmissions. It is very common for these servo bores to ware, specially the overdrive servo bore. I've seen that on many units the servo gets stuck and it brakes from the base, and the most common issue would be broken and burned bands with Gear Ratio Error codes.

Awesome video Hiram, When it comes to transmissions, You are the man. I've been watching and learning from all of your videos, but i cant find any answers to my trans problem. I have a 96 explorer 4.o with 4r55e transmission. One day the transmission went out as in all the gears that i selected were all forward gears, even park and neutral. The engine was under load all the time. I am a pretty good mechanic when it comes to rebuilding engines, axles, and manual transmissions.In addition to watching you i felt confident in rebuilding this transmission. So i ordered the rebuild kit which included all the gaskets, clutches, bands and o rings and misc. No hard parts. Rebuilt and installed transmission, New fluid(drained old fluid, didn't do complete flush)What i did find during rebuild was that some of the clutches were welded together and the fluid was filthy. Nothing else seems too bad, But i did replace all clutches and seals. Also, I didn't adjust the bands. I just put them back where the were.Now, my main issue. When i select a gear, I get either no response or only reverse. Park is park, reverse is reverse, neutral is neutral drive and overdrive -no response, 2nd -no response, 1st is reverse. I don't know whats going on. I know this is a long story, But if you could point me in the right direction, That would be greatly appreciated.

I did this job years ago and ended up almost scrapping the case when attempting to bore with a power drill. I started with a step drill bit so that the larger hole I was making stayed concentric to the original hole, then finished up with a harbor freight adjustable hand reamer. Worked great and was easier to handle than using a reamer in a drill. Just my 2 cents. Thank you for sharing!
Great video, I'll be tearing down my trans this week and probably going to do this repair
Excellent Video, much appreciated, you make it look easy for a novice like me.
BTW thanks for your videos, I'm in the middle of rebuilding my first automatic transmission. 5R55S.. 2007
How'd it go? Did you document it anywhere online?
Hiram thank you for great video.
Thanks Hiram.\
When I did get a code it would be pressure solenoid b and OD flash..
with the updated solenoid pack the same results however.... I have had the servos out and even measured the servo bores and there is little play or out of round to the overdrive bore only minimal .002 " front bore to back bore dia difference......seems ok or much better than typical worn bore..so it seems.
Because I also have no TC lock up ever now thought it might lead to a cause that is effecting both 5th and no TC lock...? this also happened overnite....when my son was driving but before that all functioning as normal....5th and TC lock....
since 2nd also uses the overdrive servo bore and it works I was thinking something else going on....replaced the output shaft speed sensor too....
thanks for fast reply!! Mike
Great vid man. Ive had my truck for 4 years. ive always suspected the torque converter was the cause of my delated shifts, delayed engagements (from p to d especially when cold) and it used to whine. ive replaced my solenoid pack, and valve body a year ago. just had the ford dealership do a flush. truck shifts well but my torqueconvtr never locks up now, 4th or 5th gears. after a minute or 2 at lockup speed, od light blinks and says check trans on the screen. took it back to the dealer...
Not the Malibu transmissions.There is a red screw on cap real easy to find.Then go underneath remove a plug near the passenger side axle to check fluid level.Runs out,it is full while running.The Camaro,there is a fill procedure too.
Please come to our schools for trans car units. Thanks
Thank you so much hopefully it works out love your videos and all the info
Thank you Hiram for doing this video you the man
Hello Hiram. I'm from Kazakhstan. We do not have a 5R55S ServoBore repair service. Please tell me where I can buy such a repair kit. If this is not possible, please tell me the dimensions of the trimmers. B.Thank you very much
All of Chevy's vehicles have either a dipstick or a rubber grommet/plug where one can be fitted from the factory or aftermarket.
Thank you very much for your video. Very informative. Please send me part number of servos bushes kit.
good day, I have a 2005 explorer sport Trac xlt.... The reverse stop engaging instantaneously, and 4wd does not engage either. forward gears are fine. Can you tell the the possible issues and remedies please. Thank you
Thank you very much for sharing your knowledge.
Hi Hiram and thank your for your last reply... 5r55W 2002 explorer
Question...when reassembling the front oil pump housing what would happen if the selective thrust washer clearance was too little or too much...outside the .012"- .018' clearance? does this effect operating pressures to possibly cause a Low solenoid B OD flash code? last inspection of a pan drop there were also signs that one of the carrier thrust bearings failed with remains in the pan....! Aside from losing the bearing surface where it came from this could also effect fluid pressures because of how it would now effect that clearance on the selective washer area?? your thoughts?.... I think I know I'll need to pull and replace it and check proper clearance....
I also tapped the OD servo cover to monitor pressure on the OD servo piston while driving..... it is getting pressures when it is supposed to for a 2nd and 5th shift but goes to about 120psi then drops and holds at only 70psi with apparent non full engagement of the OD band....essentially eliminated the cause of blowby on the servo stem being the cause of non shift....
thoughts?
thanks!!...still learning here!

Hello friend good afternoon, I have a 2002 explorer with 5r55w transmission, I would like to know what I should check, since my car when backing has NO FORCE, when the site is flat there is no problem, but for example, when I leave my garage and the rear rubbers of the car lower the sidewalk (and remain in the gutter), it does not keep backing me down, it loses strength, there is not enough power to get out of this position even though the engine accelerates very well, that is, the car in this position (the front part above the road and the rear part below the road), loses the power to go back, it just feels that it moves but does not leave the gutter, I must put it in DRIVE, climb the sidewalk again and give it hard back to get out
Hiram, Is it a good idea to just perform this repair as a preventative measure, regardless of the condition of the servo bores? Or should this only be done on a case by case basis?
Thank you for your time.
thank for the video about 5r55w transmissiom rebuild I did it and it work find
HOLA HIRAM,tengo un Honda fit, cvt 2007, SWRA.. no camiana en R ni D, en ninguna velocidad, me marca p0 1888, sensor de velocidad del cvt.. no hay nada de refacciones aqui en mexico , me dicen es hecho en brazil, crees sea ese sensor causa de que no camine ? hay una pagina de whats up para escribirte ?
Hi Sir, my wifes 2002 explorer 4x4 had the cover on the servo bore pop off and lost all the transmission fluid. What would cause the cover to pop off? The retaining ring was there and the servo bore cover was loose. Is this something that I can just put the cover back on and seat the snap ring to hold it in place and refill with transmission fluid?
Whats up with all the metal shavings? Do they get down in the trans? Do you have to clean out the trans?

Wondering if you can help. First off, thanks for the videos, they're great! I have a 5r55w out of an 02 Explorer that I am rebuilding. After going through and inspecting all the parts, I noticed in the bottom end of the pump where it goes into the coast clutch (?) There looks to be what is left of a bushing/bearing. It seems this is not a replacement part since I can't find it anywhere, but I've noticed 2 different style pumps? Some with exposed bearings and some without? Can this be changed or do I have to replace the pump? Thanks
hi Hiram,
honestly speaking your videos are quite helpful. by the way i wonder if you are planning to broadcast a video about 6F35,
thanks,
Automatic 5r55w 02 explorer, wondering if you could help me narrow down an issue. OD light starts blinking after hard shift from 2nd to 3rd. I can bypass the problem by restarting my truck and manually shifting to 3rd after the 1st gear. When I get to 45mph, I shift back into drive and it drives just fine in the higher gears. Had it rebuilt 3years ago. Same guy tore it down a month ago after sprag busted. Can you offer any advise? Thanks for the videos.
greetings, I spend with my ford explorer, entered the transmicion water. repair the radiator. drain the oil. and I have already done 2 oil changes, but I feel the changes as heavy. improved oil color but not 100%. What do you recommend me. the model of my transmicion is 5R55S. perdo by language. I am from Venezuela
nice video got same transmission i need the size tool to remove the fill plug to add some fluid and a non mechanic change my filter and new gasket when he remove the pan a piece of aluminum looks like a fork .not only that he did not know where to fill up the trammy back with fluid . i told him don't touch no more my suv and leave now the car don't engage any gears what could go wrong , im thinking low fluid or bad solenoid .
I don't know why companies are doing this other than for maintenance fees, but it's safe to say Chevrolet's the only other vehicle manufacturer that still puts dipsticks on their transmissions. At least they still want their customers to know how to replace crap on their vehicles.
Hello,
Can you give me an idea if what is the sequence of band adjustment of the 5R55W, 5R55S and 5R55N.
Thanks
Hi, Great videos! I have a 5r55n trans that stopped going in reverse.How can I fix it?
Hi Hiram,
Question..hopefully you have some insight to help.. : I have a 2002 exporer...5R55W..... rebuilt and new TC.,.rebuilt valve body and updated solenoid block... one day lost both 5th (overdrive) and no torque converter lock up at any speed. both happened at same time... if I let off of gas pedal at any speed the rpm's drop to idle...
thoughts? thanks!! Mike
Thanks Hiram good info. Great video!
What is this repair kit called and what was the site I can order it from?? I would like to order one asap.. I habe yhe exact same problem.. the ttans shop I took it to replaced the belt and that was all they did.. the drum is essentially destroyed and I see scaring in the bores as well.
Just a tip, drill SLOW. The slower you drill the better it bites the sharper your bits will stay.... Im a metal fabricator and fast drilling is forbidden ! you can always spot someone that hasn't worked with metal when you hear that drill on FULL DULL
its aluminum ..he is basically cutting butter
Good video sir. Thanks.
Great Video.
Necesito saber El nombre de la pieza que va en el boquete que esta debajo del input speed censor!! La necesito pero no se su nombre!
hi there guys I m a beginner rebuilding transmissions I just rebuild ed one and now it won't shift gear we before all that was wrong was that it needed the 3 4 clutch
Same problem occurs with the Lincoln LS and such.
THIS IS FOR HIRAM GUTIERREZ.. cuanto cuesta el kit para reparar el OD bord en las transmisiones 55RW?? grasias
is this issue common on the 5r55e ? and if so, will these same tools and parts repair it?
very nice sr!
THANK YOU
...(cont) but they said that there is no code (just the erro msg flashing). ive had 3 flushes in the past 75k miles and since this last one caused my converter to not lock up, my shifts have been quick and smooth. acceleration is good as well.
two issues; No converter lockup- ever, and my the delayed engagements happen more frequently and take longer to engage. its an 03 mountaineer. trans has been replaced before. i want to know if this the symptoms of a faulty tq converter.
Hello, I'm looking for your clutch pack clearance video for 5r55e or 4r44e.
The 2010,2011,2012 and 2013 Camaro automatics don't have a dipstick.Even the Malibu transmissions don't have a dipstick.
What's the sign of bad servo ? Please help
Hello dear, I have a Ford explorer xlt 2002 that I have problem with the transmission. How would I be able to contact you? Please I need assistance from Sweden
Great work sir like your videos.
Love the channel!
Thanks! Great video! I have a question.. Is it possible to replace the OD band without removing the internals of the transmission?? That means is there enough room to remove the old band and then install or wrap a new band around the drum while it is still in the case?? Thanks Much in Advance for your patience!
Bob Duvall why not a Stainless Steel sleeve it would last forever ?
No you have to remove the pump
Great video, thanks for sharing your knowledge.
Quick question, is the 5r55s from the Mustang the same internally for either the v6 or v8? I know the case is different on the bellhousing, but i wanted to know if the internals are exactly the same. Thanks a lot. Abel

Thanks Bro! I've been waiting for someone to come out with how this is done. I have had to build a few of these units and have not seen the servo bore damage. I'm told i should sleeve every unit. Is that true or just as needed? Thanks man. I look forward to your next build.
is it possible to re bore the 5r55s again once its been bored i have one that the brass bores are worn out again
Best thing in my mind would be to take out the old bushes and replace with new ones.
HOW MUCH ITS THE KIT COST. THE ONE YOU USE FOR REAPER THE OD BORD ON THE 55RW TRANSMISION
hermano me podrias pasar el numero de parte de la herramienta para comprarla
muy buenos video Mr Hiram yo tengo una explorer 2002 y me repararon la transmision pero a veces retarda los cambios o los regresa de golpe al irse deteniendo....sera algo electrico o quedaria algo mal reparado ....gracias
gracias....si ha ido funcionando mejor con el paso de los dias ..pero aun asi no me convence la reparacion.... la llevare al taller para para preguntar si le hicieron clear keep....gracias y saludos desde nuevo laredo mexico...de nuevo gracias...
olvide comentarle que me dijo el mecanico que es nesesario un cambio de aceite ala transmision alos 15 dias de la reparacion .. cambiar el filtro para sacar la rebaba es nesesario este cambio de aceite...... son 8 quartos de mercon v ?.......es lo que me dijo....
ok estonces para hacerle el cambio .de aceite..... gracias por su tiempo.........echele ganas y muchas gracias nuevamente.......es bueno saber un poco de todo soy soldador de artesanias pero me gusta moverle ala mecanica ...por eso todas las preguntas .......

Hola Hermano quisiera el video donde raparas el cuerpo de valvula 5R55E 4R44E 4R55E TRANS VALVE BODY W SOLENOID) pero en español . Agredezco me ayudes ...
How do u keep update on new transmission
i have a 02 ford explorer xlt sport track, the problem i am having is i have no gears before it went out completely i would be driving then suddenly lose the gear and it would just rev then slam back in after a second or two, anyone know what could be the problem?
Lastarius/Crys did you figure out what the problem was?
Hi, a Question please I have a 1999 ford explorer 4.0 5R55E with a code PO715 I was told they need to open the transmission to replace the speed sensor.Is this statement correct? asking for $600.00 if nothing else it's broken.
They are lying to you the 3 speed sensors are on the outside of the transmission
On the 4R44E/5R55E the turbine speed sensor is internal bolted to the center support.
On the 5R55S, 5R55W and 5R55N all 3 sensors are external.
5R55S, 5R55W and 5R55N came out on 2002. On those all 3 are external.
4R44E and 5R55E on that have the input "Turbine" speed sensor mounted on the center support. Internal to the unit.
Output speed sensor is external.
Good info
What causes these, whats the transmission problems
they should of had it designed with a hardened bushing or sleeve from Henry Ford to begin with
do u have a video of a 2000 xk8 jaguar transmission
what is the torque specs for 5r55wvalve boby
Did you ever find the torque specs for the valve body
can't hear it
Friendship fly shuplier
Hiram thes transmissions i understand have torque convertor studs, whats the trick to installing thes mother fuckers? i know atransmission be a hell of alot easyer then ane engine, i just installed my 4.0L SOHC last night, what a pain....1
you waste a lot of transmission fluid with these makeshift method to add trans oil, dip stick way worked fine, why re-invent the wheel..

audio sucks dude!
