- Tearing down the 6L80 valve body today. This unit is being build for an 07 Cadillac escalade. This video will show how to tear down the valve body as well as some important information for update to the 6l80 transmission.
In the coming videos we show the final assembly and testing of this valve body. Thanks for watching and see you in the next video.
Thats my trans right there. Transmission is installed on my 07 escalade. Just waiting on the guy to program my new tcm.
Excellent work youve done so far david.
Thanks Carlos I appreciate it
Mine just took a shit and I decided to dig in and see if I could fix it thanks to your vids. I lost all forward gears and only have reverse. I tore the valve body apart and pulled out all the check ballz except I was missing one and found it stuck in the gasket! Hoping that this is it. No metal shavings, tranny oil was really good, no stink etc. I bought a new Tehcm and spent the money for the program and just under $800 it wasn't fixed. Hoping this is it. I don't really want to learn to rebuild one of these but I'll give it a go. I just got done with the GMC 3.6 triple timing chain job so I've got a good stomach for there things!
Did it work? My 2015 Silverado has no bald eagles in forward gears unless I rev it a little it will eventually slowly start to go, but even then it's sluggish. I have the pan dropped now looking up videos on this about to order the kit from amazon.
I just lost the tranny in my 2015 Silverado and man do I wish I lived closer to you I would definitely bring to your shop
Thank you for that I appreciate it. If there's anything I can do to help just let me know if be glad to help
I’m Just in the process of changing my pressure switches on my 6l80… it was down shifting from 2-1 will slow and almost like a push… I’m hoping it’s just those little plastic films … but now I’m worried after watching this 😟😟…. Anyway… excellent video🤙👍🤙
Thanks good luck with your switches 🤞
I use to rebuild caravans a lot, the transmission were garbage but an absolute goldmines lol
If I just had my 6L80 transmission rebuilt, would they have rebuilt the valve body as well?
got one that we rebuilt and thought this is a fix. after making it around the block i get a bump after coming to a stop and 6-8 second delay when park to reverse or drive after warmup . TRNW was a litte help but not real clear. actually the only thing not new in this trans is the TECHM . ill try to let u know
Great vid, Great info!!
What can I upgrade on my transmission to make it last longer . 2017 GMC yukon xl 4x4 ... great videos...
5:54 is the start of actual video. 🙄Youre welcome people
Hello, I would like to know how many Transmission Valve Body Check Balls there are in the 2012 Chevrolet Tahoe.
Wow Brother Came to Connecticut,I have 2007 gmc yukon denali Code PO1776 stuck selonoi 2,don't know what to do,I take the oil pan but I'm afraid to take the Body Valve out,Probably do it Truck is Pay-off long Time ago,Great Video 📹
I replaced the passage sleeve twice and it’s still leaking from the connector. I have a new TECHM installed as well. At this point I’m tired of dropping the pan to address the sleeve. Plus the pins aren’t loose.
So I am working on a 2007 Yukon Denali 6L80 trans. If it sits for days if shifts just fine. But after a few days of driving it will suddenly stop shifting. It does have a P2723 code. I’m thinking it’s a shift solenoid pack or possibly valve body issue. The trans does not slip. But occasionally when it engages reverse it’s like it slams into reverse from increased line pressure.
I’m getting all pressure codes in a 6l80. Could the laminate discs be bad. Transmission still shifts fine. I’m scratching my head here. Any help is appreciated. Could the laminate discs be bad. ?
Another good vid
Gonna stick with my old crappy 4l60e. Those 4l80’s have too many parts 😳
Lol thanks it's definitely a lot of fun
will this tear down work for the 6L50 i hear they are similar in build
Dear sir, could you please advise. I have stock 6L80 on my 2011 chevy camaro SS. I found UPDATED Valve Body Spacer Plate w/ 8 Check Balls 10-Up. Can I use it on my stock car?
You can but if your going that far do a zip kit
Nope no engine breaking in low
@@expressautotransmissiondav4207 zip kit is just welcome or mandatory? I got TransGo shift kit SK6L80
I prefer the zip kit but that transgo kit would be great as well
@@expressautotransmissiondav4207 does specialist need any specific tool for replacement separator plate and check balls?
I have a 2014 Chevy Silverado with 6l80 and had some codes come up was letting me go into any gear so looked up the code all saying clutch pressure solenoid shut off and how can I test them to see if they’d re actually bad how many ohms because I haven’t had any luck on the internet so could you help me out
I have a 2013 Chevy Caprice PPV 6.0 with the 6l80 transmission it's acting up from a dead stop. It feels like it's surgeon for a second then shifts then it drives find
Hi! I have a bmw 128i with GM transmission. Is having wierd vibration like if the road would be grated when I accelerate it mostly from 2nd or 3rd gear. How can I get that repair kit, like the balls that shrink 😂?
I have a Corvette 2007, I’m not doing a rebuild, just working on the valve body installing the Sonax zip kit and the Transgo Clutch select valves. It has the original separator plate. Is it mandatory to update it with the new AC Delco plate 24245720? Thanks for your help.
Not mandatory and anytime
I would like to replace it with the updated Delco plate 24245720, according to the Parts store web sites, it’s for 2008 and 2009 models only. What do you recommend?
I typically change my plates in the 07-09 stuff I use the sonnax zip kit with the second design plate.
@@expressautotransmissiondav4207 Great! Thank you
8:13 that’s hilarious, I’m literally watching this video for the sole purpose of figuring out which bolts go where - and to get the torque specs (put in new pressure discs on my 07 Escalade TECHM)
I got codes for trans mission fluid temp sensor
Input speed sensor no sig
Output speed sensor intermittent
Torque converter clutch stuck
Shift solenoid valve 1
Could replacing a piece like this help?
I can drive my car for 15 secs then it just revs up when i moving. I have to turn it off for 15 seconds then drive again for 15 secs then it surges again.
Checked trans fluid its level but black and stanks almost burnt like
Hi brother thank you so much for sharing your video I got a 2008 Cadillac Escalade 6.2 L all-wheel-drive my car is it stacked on drive they won’t go back can you give me some suggestion do I should buy another transmission or only the valve body? Thank you so much
First things first diag is everything. If you want to reach out to my shop ill gladly help you diag correctly.
@@expressautotransmissiondav4207 thank you so much I am in Colorado where is your shop?
Baxter springs Kansas
@@expressautotransmissiondav4207 Can you tell me what should I do with my transmission thank you I know a little bit about transmission engine I can do the work If I change only the valve body what do you think is that work thank you
Let's start with the basics. What exactly is the unit doing.
Whats the best 6l80 tehcm if one exists or they the same?..you have a part#? Does 4wd or awd matter? I currently have tehcm part number 24275872 and 24275873 you know the difference?..
I'm not sure about the difference between the two I know I prefer dealer only techem for them.
@@expressautotransmissiondav4207
It is an ac delco part#24275873 im putting this in a 2 door tahoe 6l80 is 4wd with an ls3 lsa supercharger making it awd with a awd nv149 transfer case.are they programmable if so it should work correct? The valve body is the 955/945 C with the upgraded 8 balls...is that a problem?
If u buy a new value body do you have to have it reprogrammed?? If so can u do it yourself or does it need to go to the dealer??
Dealer if techem is replaced
L680 YUKON DENALI, SHOULD ALL SOLENOID BODY VALVE HAVE TO SOUND SAME ALL OF THEM ?? PLEASE HELP ME
so my mom's having a bad day. Her brother passed away earlier today and when she went to leave the house to visit with family in her 09 suburban 5.3 2WD the check engine light came on and she was panicking. I let her use my car so I could check hers. P0751 "Shift Solenoid A Performance Stuck Off" It sounds like you said the solenoids are part of the tehcm? so can I just replace it with a used tehcm for now? and are 6l80/6l90 2WD/4WD tehcms the same? will it need to be programmed? She is fixing to trade the suburban in on something new but she needs something to drive for now so it doesn't have to be a long term fix or full rebuild. Thanks.
I've never tried swapping with a used one. The techem is vehicle specific, yes it will need programmed. Also if a clutch select valve hangs it can cause that code.
Can a bad value body trigger a code?
Quick ? I recently replace separator plate and check balls, do I have to put any assemble goo to hold check balls in place??
Not a requirement
@@expressautotransmissiondav4207 Preciate it🫡another question…
@@expressautotransmissiondav4207 when adding 8th check ball to the 6l80 and new updated plate is there any tuning required??
@@NewBluu93 I tune all of my 6l80 trans I would highly recommend it
@@expressautotransmissiondav4207 I had my trans tuned a while back, would it be an issue if it’s not tuned after adding 8th check ball with updated plate with the 0.54 orfice?
"Biggest pile of turkeys the world's ever seen..." I thought that title went to the US Congress, with a close second being the Detroit Lions. The original 6L80 was that bad, huh?
Bahahhaha yes it was right up there with government work that's for sure. How's the transmission life treating ya John Allen
@@expressautotransmissiondav4207 I'm just a backyard mechanic who's always been interested in transmissions even though most of my work tends to be north of the flexplate. I like your channel though, especially when you work on older stuff like the C4. Automatic transmissions have always intrigued me after seeing the valve body of a TH350 when I was 18. Blew my mind that there was a hydraulic computer in there. Anyway, keep the videos coming. Great content and humor - you deserve to have 600K subs, not not 600.
@@johnallen1901 thank you so much for that I really appreciate it and feel we try to put out some nice content.
Where is the tcc solenoid in that
My 6l80 is giving a TCC Stuck on and the transmission is acting as if the TCC is locked. Could this be a solenoid/TCM issue? All the sudden/shifted fine before it happened while driving the other day.
Very possible a stuck solenoid or vakve
@@expressautotransmissiondav4207 thank you! I'll probably have to go this route then with the TCM/valve body rebuild
Hey I Have A 2012 Chevrolet Suburban And Got A Engine Code P2723.P2723 indicates a problem with the electrical circuit for the clutch pressure control solenoid 5 in the transmission. What Should I Do?
Take it to a reputable shop. Be prepared to have the techem replaced.
Oh my...I only understand 4L60E but I have interest in technology
I certainly wouldn't understand that ... transmission..at all and I don't own that type at all...if I did I'd be bitting my nails and taking asprins....
Haunted House transmission videos...lol
Lol thanks Jerry I bet it hot at that speedway up there
Motorcycle racing at the 500 track AND .....heat wave has ended fall season is begining trees are loosing green soon
Speed sensor clip already kicking this guys ass ha ha. 6l80e are really easy to rebuild. Stock or modified. Just inspect your part and only replace what need to be. Don't need to waste money on so called upgrades. Have fun building
So can I just replace the ball in the valve body an put it back together an use everything with no new parts or gaskets
How u check 6l80e techm ?
There are many ways to test one I feel it should be replaced on every rebuild if you have a specific area you would like to see tested we can do it.
@@expressautotransmissiondav4207 why don't u make a video on it that how to test a techm plzz if u can I can't come there cause I live in Kuwait
I'm down I'll get on it
@@expressautotransmissiondav4207 thanks 👍
