Appreciate this, immensely! Pulled my own 6L80 from my 2015 Sierra 1500 4x4 with almost zero issues. Only one exhaust manifold bolt was a severe pain but I ran up and purchased a bolt extractor and slid a 14 mm over the nut on the driver side and hammered it in good and tight and used impact to back it off without damaging the studs.
Man you are a saint. I can’t even begin to tell you how much this video helped me out. My transmission just blew up on me in my ‘15 Silverado with 152k miles. However I just had a baby recently and I’m in my off season for work, so I don’t have the money to take it to a shop. Followed along with your video and got my 6L80 pulled. The most I have ever done before is change a starter and brakes. So I am not a mechanic by any means
2015 Sierra 1500 4x4 here, yup, 160k miles and converter went out. Pulled transmission myself using these vids. Can't begin to say how much money I saved. So grateful.
Amazing video. Tomorrow am doing my first Rear main seal on 2018 escalade and this was very helpful since i have access to general motors service information but is not the same as watching somebody do it . Thankss
Bless you I just done this 2xs in my 2009 avalanche for a failed TC 2xs!!! Literally last night on my back in my yard. I am a pro now! Lol All jokes aside, great video. I wish i had a lift.
@@expressautotransmissiondav4207nice video. Can you swap a 2013 avalanche 4x4 ltz 5.3 black diamond tranny with a chevy silverado 1500 4x4 ltz 5.3. Both have 6l80?
Lol your custom in house hook tool is awesome. I have a lathe in the shop so i have a hooked rod for dealing with swarf its like 3 foot long worked perfect moving stuff on the upper bellhousing bolts
Was wondering if you might help. I realize it’s a stretch diagnosing something long distance. I would appreciate your opinion very much. I have a 2018 Escalade, 26,500 miles has brand new tires, I thought it might help or solve the issue. Didn’t . It may be 2 issues or it could be related? The truck has a constant vibration at all speeds, but it also vibrates slightly or idles roughly at full stops. The engine feels powerful with no lags in acceleration. Very occasionally I notice a clunk when the truck shifts at a very low speed. The vibration is noticeable on the steering wheel and the seat. 2 dealers have told me that’s the way the truck is suppose to run. I asked them why it didn’t run like that brand new and one said , “ We can certainly take a look. I can have the shop foreman take it for a ride. Unfortunately, you are correct about one thing, and that is that we often get complaints for ride quality such as this. As mileage increases, components become more broken in.. and in turn, yes, can begin to not feel up to the same quality or smoothness that they once had. If the transmission is feeling like it is either sluggish or slipping, a transmission fluid change can be tried yes, and that may certainly could help. But at the end of the day, if the vehicle is operating in good condition, and no components are showing signs of degradation or failure, then really it may not be something that cannot so simply just be "fixed." “ Personally I think it’s an excuse to avoid all the work that might be necessary to accurately diagnose the problem, but I’m not a mechanic and have no idea how to figure out or diagnose issues. However I do love watching professionals like you perform amazing repairs. Thank you!
To diagnose something like that would definitely be very involved and you are correct I think current opinions may be far fetched or even completely wrong. However if I was to start to examine a vehicle with that type of shake I would be starting with visual inspections. I would look at motor mounts and we'll as check fluid levels and conditions on all sumps. If you have the same or very similar shake at idle as well while moving I would suspect something around engine area or converter. Another area of concern is the idle vibration. I would be reaching out to other qualified shops in your immediate area for a second opinion. Having someone else look at it but not touch it.
@@expressautotransmissiondav4207 thank you for your time really appreciate it. That gives a bit of information when I get to the shop next week. At least I’ll have some intelligent questions to ask.
Thats how it's done, Plan on doing this task on a 08 DENALI XL laying on my back in the garage. Might have to rethink that? Great "realistic" R&R of a trans/transfer case! Thank you!
Great Video it helped me do the job. I got the trans swapped only problem left is the vent lines one goes to the transferase the other to the trans were does the third go? 2014 Tahoe thanks
Awesome video, mine is a 2007 yukon XL 5 3 4X4. No problems at 191k miles, no?idea of it was replaced. Just bought it. Only issue is lots of leaks, most likely the o-ring from the oil pump, seal and clutch o-ring the one in the shaft. will need to be replaced Im only planing pn use it like once a week. So im hoping it will last me lots of years more. After replacing those, and didnt know about the thermostat bypass. Dont know why GM put it if it fails?
An absolute wealth of knowledge. It’s a shame this 6l80s are such trash designs. Even if I watched this 9 times over. This job should be left to someone that specializes in. Converters an transmissions. There’s so much that goes into it oh my goodness.
you have to change your fluid every 40 to 45,000 miles regardless of what the book says. These trucks you have to follow the severe service intervals or better. I’ve done that and put a lower thermostat in it many miles ago and I’m at 196K on the factory 6l80.
Good video looks like you have a lot more room to get to everything im just struggling hard on the floor with a super muddy truck but i decided to leave the tcase on both the donor silverado and the dead sierra. Is it just me or was 4l80e's easier?
Good video, you lose audio in a few places tho. Like around 26:19 I couldn't get the truck in neutral last time and had to put everything back together. Saw RainmanRay just took the shift lever off the transmission and used pliers to turn the lever into neutral? How do you get it in neutral if you put it on the jack stands in park? BTW don't know if you mentioned it but when you're showing the shift lever at 26:22 the shift cable bushing looks to be nearly wasted. THEY WILL EVENTUALLY FALL OFF AND YOUR COLUMN SHIFTER WILL BE INOPERABLE It happened to me. Sketchy af. And will happen at the worst time and place. There's a kit to fix them, a little aftermarket bushing and a snap clip. You gotta drill out the original hole tho some. it's pretty easy. Always check this bushing tho, not fun to have the shift lever fall off while you've just shifted into drive and the truck is running and now you can't shift back into park. Should have been a recall on that bushing.
That is a well-done video, and your work is excellent as well, are you going to upgrade the torque converter? I wrap my crossover pipe 2x that runs under the trans pan with a heatshield rap, to try to lower the heat in the transmission. When I change my fluid I used the best fluid that I could buy.
That's awesome. I don't wrap them unless its a hotrod. I did upgrade the converter to a precision billet face. Thanks for watching we have a lot of fun making them..
The 6-speed in 2014+ trucks runs hot because they came from the factory with a thermostat that causes the hot fluid to bypass the transmission cooler until it reaches a certain temperature. That's why they're always at 190 degrees or hotter. If you want to reduce those temps, there a multiple ways of doing it. GM has a different thermostat out now, there are aftermarket bypass thermostats made specifically for the 6L80, or there are ways of modifying the original bypass (not recommended but many guys do it).
Awesome video man. Helping me out a bunch on my first trans drop. Any idea of why my torque converter won't spin freely/easily?? I was able to get one nut off but can barely move it to get to the other two. Any ideas would be great. (Trans has a neutralizing problem/cracked drum situation) according to my mechanic
There are three converter bolts if you can access the front crank bolt you can use a 1/2in ratchet to turn the engine over to get to the next bolts. Also not having any background always make sure the battery is disconnected and if the vehicle is on the ground use good quality jack stands safety is number one in my shop.
Me too Please 2017 Silverado 5.3 L First Transmission blown at 60,000, put a brand new one, Had a lifter stuck at cylinder 7, Told i needed to put a band aid on it by repairing left bank for $6000 or engine rehaul for $15k said no thanks did a dod/afm delete myself at home kept everything stock and replaced the camshaft for a gm delete cam because i had a chunk of metal that was taken out of it. That was at 100,000 miles ran great if not better then at 120,000 miles second transmission went out again torque converter failure and check ball#3 stuck in plate metal all through. Currently rebuilding my transmission myself i won't let anyone work on my truck from this point on. oh when i called gm about my engine and i complained on bbb website they called and offered me $1500 gm certificate towards the purchase of another silverado i laughed at them.
Audio is gone during trans dismount. I don’t hear an explanation for prying on the machined bell housing surface. Those pry surfaces often work well, along with an up and down shimmy of the Jack.
nice video the sound needs some help .but any way these transmissions have all the same issue "HEAT" that dumb thermostat that control the trans temp are set to high and GM knows it!!! they swiftly & quietly replace that stat with a repayment one with a 50* lower open rate in later years .The trucks 2014-2017 run a 200* + and burn up the fluid & converter. The GM REPLACE stat now open's at 160*. I have a 2014 and bought a bypass plug that replaces the stat my truck run's now at 140*-150*.
Great video!!!! Getting P0741 after swapping converters. Although shudder is gone, now I’m having this code. If the trans shifts through the gears and the converter locks, does that mean all the connections are fine? When the CEL shows, it does the no 6th gear, no converter lock scenario. I’m hoping I don’t have to swap converters again.
Although I will never take on this job, need tools and a shop, it tells me just what someone else is going to do, and it makes me so much more mad that this has to happen to my 44k mile 8spd. Thanks 🏁👍🏾
Whats your opinion on the transmission cooler thermostat that bolts on the side(Bypass kit), im seeing lots of people buying a kit to modify the thermostat inside that block and it drops the transmission fluid temperature significantly
I just removed mine at home for my first time removing a trans. Video was very helpful. But do you have one to install it back in. Question how hard is it to line up the fly wheel to bell head when going back in with new one?
Great video, just replaced my transmission but didn't solve my problem.. not sure if it's rear diff or transfer case. When starting out in drive there is sometimes a second delay before the vehicle starts moving after hitting the accelerator, this happens when at a stop sign or starting out. Occurs about 50% of the time. Any ideas on the issue would be appreciated? Thanks
You mentioned that the truck was shaking,,,I have 93 chevy van that shakes in park and neutral to ,,,after a rebuilt trans and new TC,and numerous other parts that I have installed,,could it be I have a new bad TC? Something feels out of balance.
Brother ,!, I have a 2014 Chevy Silverado with a 5.3 , well I changed the trans filter and fluid and even put some shudder fix in it. Well the truck will drive now and does good until you get to overdrive then it shudders really bad..the trans magnet did have quite a bit of sludge..the truck has 140 thousand miles.. before I changed the filter and fluid the truck would come to a stop and would act like it was in neutral while you was in drive..all this happened in 2 weeks of time.. I really think the tourge converter started this mess.. as of right now I’m still riding it and it does good until it shifts to overdrive.. what would you recommend... another filter change or a complete rebuild or maybe a torge converter replacement.. Thanks brother
It's time for a rebuild. This is a common scenario for this transmission. We're starting a build series soon on the 6l80 family of transmissions, if you want to follow along we're gonna show how to disassemble and do a complete rebuild.
@@expressautotransmissiondav4207 sounds good brother. I’m actually in the process of taking out my trans today. I’m fighting with the two top trans bolts at the moment. So I’m trying to watch to see what you did. Lol
Does it matter how the drive shaft goes back on? I didn’t mark it and I did the transmission swap (video helped a ton!) and now my truck shakes. It didn’t at all before. And I just installed a new drive shaft OEM GM part. And it still shakes. Your help would be great
@@expressautotransmissiondav4207 I feel the shake in the drive line. In in the floor. Steering doesn’t shake wheels are balanced. Etc. you can feel the shakes at certain speeds and you basically can hear the shake like a hum per say. Before I did the trans swap the truck drove smooth no problem whatsoever. Did the swap and out the original driveshaft back. And I could feel a shake. Did a 180 on the drive shaft and still felt a shake. Put new u joints still shook and a more than before. So to insure it wasn’t a bad install of u joint got a whole new shaft. OEM GM and still shakes. 2014 Silverado 4x4 I
Great video! I have a couple questions. Are there any torque specs on any of the bolts when reinstalling? And is any loctite needed on any bolts when reinstalling? Thanks
I use loctite on all of my converter bolts. I also like to use factory specs for my tcase bolts as well as u joint strap bolts if you need any of those specs lmk and I'll get them to you.
if you do a complete 6L80 trans swap do you need to relearn or program the trans? or is it a bolt on plug and go? my TC and trans went out at 113K on my 2016 sierra but i found a 2018 6l80 from a silverado with 5K miles on it. (truck was totaled but trans and TC still in good shape). curious if i need to program anything...
Good Afternoon. I’ve recent got my converter changed and now my fuel Gauge isn’t working , is it possible they didn’t hook something back up around that area ?
It doesn't line up to a certain spot. However there is one converter bolt hole that is oval shaped if you install that bolt first the other two will always line up. If not then you have to leave the bolts loose till all three are started before being able to fully tighten them.
Side question Does anyone know what issues if any there may be if I eliminate the exhaust pipe that runs under the transmission pan? I'm sure that contributes to the death of these transmissions along with making fluid and filter changes more difficult
I dropped the pan for a fluid change, added a drain plug and then used some reflecta-heat with adhesive to the front and side of the pan in order to block much of the heat soaking into the trans pan. I also installed a trans thermostat bypass fro Superior. That and the Sonnax zip kit made a HUGE difference in overall shifting and cooling.
David I know the torque converter is a weak link. Have no problem with my 2018 Silverado yet, what is your opinion of replacing the trans cooler thermostat with a Sure Cool to lower trans oil temperature?
@@expressautotransmissiondav4207 more questions please. Is it ok for me to shift in all gears to make sure my installation is right before even towing it to the dealer ?. When pulling the truck onto trailer. Can I shift to neutral, just to make it easier to winch it up. Sorry to bother you, I just want to make sure if its OK to do so before the tow guy comes over next week
We replaced with used transmission. Getting no communication while trying to reflash tcm in used transmission. Is the TCM considered an internal part of the transmission and should be under warranty or is the tcm considered seperate from the transmission warranty. Technical question but just curious how most technicians view that.
I view it as the tcm is bolted to vb. If it wont program probably wrong tcm for specific vehicle. I would check to see which tcm.you have and which one is needed.

Just constructive criticism…. The audio was killing me. It was good, shitty, silent, good, shitty and so on. Made it hard for my adhd ass to pay attention to what was going on because I was too focused on the audio being hit and miss.
