As a tech, I've had really good luck with this stuff, especially with Nissan transmissions. It's a pretty sold friction modifier. With that milage, I don't know if it'll help much unfortunately. Those factory clutches are probably about done for.
I'll table this in the "food for thought" classification. Years ago an old school mechanic told me that "back in the day" you never heard of automatic transmission failures (normal use). Tranny fluid USED to have Liquid Wax Esters in it, from Sperm Whale oil. When whaling was done away with those esters were no longer available for inclusion into the recipe for tranny fluid. "Lubegard" tells the story on their website and the Lubegard product they sell is a synthetic copy of those liquid wax esters. The mechanic was telling me this tale when I took my '90 Dodge Dakota to him for all new fluids/filters throughout. The tranny was flushed and filter changed, and we added the Lubegard as well. This would've been approx. 2004(ish). Twenty years later, that Dakota's tranny is working the way it should (still).
Man so glad you posted this video I already had stuff to do a tranny flush on my 11 traverse today and picked up some of the shudder fix and it's 99 percent better thanks!
Tune the lockup out of the low gears with hp tuners. Fully lock in 5 and 6th. Boost the tc lock up pressure. Gm constantly slips the clutch. I run Mobil 1 lv atf hp.
In the torque converter tab zero out the tcc slip and tcc air conditioner slip tables. GM literally has a table to slip the converter constantly during lockup, no wonder they are failing.
@lsxmatt, so I understand this video you disconnected the tranmission line from the upper radiator location, then installed a hose to that line and to the 5 gallon bucket? Thanks in advance.
When my transmission got hot like that in my avalanche, I just change the transmission cooler to tru cool transmission cooler and never had any problems after that
I did this back in like 2003 with my 4R70W in my Lincoln Mark VIII, with Ford friction modifier. Worked great for a while. When it acted up, just dump some more down the fill tube. Lol
Just recently had a shop build my 6l80, better clutches, better drum, also put a zip kit in the valve body, put a billet tc, as well as a thermal bypass for the cooler lines in my 16 silverado. Basically built, but not like crazy billet everything built because it was having all sorts of shifting issues. Initially stemming from the obvious tc issues in the 6l80. Now it honestly drives better than the day I got it, and I only got it at 13,000 miles, and I’m only at about 47k miles now.
Lubegaurds the best stuff really! I used in my 2010 matrix FWD at 150k and got 360k out of torque converter when it finally gave out without warning signs. But around the 150 mark I had a shudder between 40-45mph
Great to see you Matt! Always look forward to your content. Lubelocker gaskets are awesome. They make them for the trans pan and diffs. Definitely worth a few extra bucks. Wish they made an oil pan gasket as well.
I have done the fluid exchange method and pan drop/filter on the last one with all my GMs. Even with decently dark fluid it's never caused a failure. If anything you extremely helped it. The modifier is interesting. My 06 Yukon Denali used to run 150-170 avg, and would go right to 200 at a hot idle. I walked a deer and changed to a Cold Case radiator, and a Tru-Cool 40k trans cooler, and ran like stock through the radiator, it barely ever gets past 150 now. Cruising is usually 130 even!
The clunk when coming to a stop could also be the front diff mount bushings. Common failure on those and since a lot of Denali and escalades are awd it can cause a clunk on decel when it downshifts or whatever when coming to a stop. I have seen it several different ones of these trucks and fixed it.
For the fluid temp, stock with a new trans, it is pretty common to see 200-210 occasionally 220 on these trucks. I’ve seen over 230 when towing. I agree though it’s way too hot. Definitely do the truecool 40k cooler mod. I have a lot of 6l80 experience with my truck. They are terrible. Brand new they are so clunky especially in awd trucks with lots of driveline slack. It literally feels like you left the transmission behind you on the highway.
So i know what Matt is experiencing as my 08 (i have owned since 2020) Tahoe has recently started doing this. My Tahoe always hovered around 180-190 even on hot summer days but recent months even on a 41 degree day i saw the transmission temp quickly climb to 205-210 so i definitely think its outside the norm. This issue is also not consistent as this will happen a couple times a month. I tried doing the same flush but no luck. One thing i can note is that i removed the coolant cap and the transmission dipstick before this started happening, trying to see if there is anything related. Im also planning on testing the stock electric fans to confirm they are working on high speed.
@@lsxmatt so i may have found an issue, not sure if it will resolve the temp climb but when i tried to run the high fan speed relay using a jumper wire….it only kicked on the passenger side and not the driver side fan. Low speed relay worked as both fans turned on. Im going to replace the motor and give it some time to see if the transmission temp rises again.
G'evening Matt 🤠 . Thanks for the heads up, I'll keep that additive in mind 🤓 . On the flip side of that coin the 4.3 V6 in my 98 S10 Blazer decided to grenade on me so I just upgraded to a purdy' nice 2002 GMC Envoy 😇 ..
My 2010 ESV does that, it stalled at a red light and started right back up, my fluid is pretty dark but doesn’t smell burnt luckily, I also have a code P0011 and thought that maybe related as well..
LubeGard FTW! Seriously it has saved 3 of my transmissions (two Aisin and one 4L60E) with shudder and still going strong! I did a full flush with SeaFoam trans cleaner for about 100 miles then dumped and filled with fresh fluid w LubeGard red. Most of the additive snake oil is a waste, but this defies the odds and just works.
Loosen the nut on the trans mount down to the end of the threads. Leave the nut on. Get a bottle jack and a block of wood. Jack the trans up via the stud with the nut on the bottom until it bottoms out. The extra two inches raised should give enough space to remove the pan. Works like a charm on the GMT 800's.
On 4x4 gmt900s A 3 ft 2x4 and a ratchet strap or scissor jack. Use 2x4 in between the trans cross member and drivers side crossover pipe to lever the pipe down.
I had the shudder, thought it was the engine. Next day wouldn’t move without RPMs. Replaced who transmission. Why not replace the torque converter? If the JMBX converters are the main failure you’ll likely get a lot of years out of the transmission.
It’s a pain in the ass to do in my garage, main reason. Plus I know if I pull it I’m gonna wanna open it up then I’m into it for a rebuild. I want to do it, just not right now.
I’ve watched all your Escalade videos today- def some good stuff! How do you feel about the trans now, I picked up a 172k Yukon xl, debating drain n fill the trans, needs more maintenance but working on it
Looks like it fixed it for now but im pretty sure the torque converter like you said is on its way out thats another reason for your temperature to climb and will eventually cook the fluid/trans might just be why that fluid was looking pretty black had some of the same issue with my 700r4 how do i know 🤔 😮 in all time will tell
My Caprice has a slipping converter clutch in the 4L60e, I got a tube of that same stuff on discount just for shits and giggles, and holy hell it actually improved things. It didn't last though, about a year later it's probably as bad as before, maybe I'll put in another tube of it. Or it's just the TCC actually going out.
Since I still can't drive my Escalade since it needs a tune after putting a new cam, deleting the vvt, duel springs etc: I took advantage to get rid of the crappy torque converter with a circle d 3200 converter and a much bigger trans cooler from mishimoto. Fwi, 6l80es AWD are not fun to take off in a garage setting 😢
Not gonna lie and I mean this in a nice way. I was kinda hoping it was going to stall again at the end of the video 😁. Then we could have got a trans rebuild video.😂 Best wishes I really enjoy your channel.
Hey Matt! I have been experiencing the same issue with my 08 Tahoe with the transmission temp climbing over 200 on random drives. I did a flush as well to see if it resolves it but it did not. Still trying to figure out what is causing it
I’m thinking of buying one of these trucks as my 2nd gen got tboned and totaled out. It’s had 3 tranny fluid changes and it is a one owner with 141k miles. It seems to have did some towing. Would that be bad?. I wish I had a way to contact you further besides the comments. I love the work you put into your videos and I’ve bought some of your merch. I really am in desperate need for creditable advice on these trucks. I’m selling my 01 WS6 6 speed TA 77k miles to a guy and I won’t want to make the wrong decision going for this generation of escalade. I hope to hear back and it would be nice if I was able to talk to you with a little more ease to ask some questions about this truck. Once again thank you for your effort in these videos!! It’s wild how I have been subbed to your for your trans am build then magically start having Cadillac videos when I’m going through this situation. Like how lucky could I get??? Very Informative TH-camr that I’m already subbed to gets the very same vehicle I’m interested in.
The pan was dumped already when the trans line blew off a few months back, the the fluid was sorta changed. Either way the shudder fix is cheap enough I would throw it in anyway.
Billet converter and a good tune seem to be the only true fix for these unfortunately. Even on the gen 5 trucks. They are great at holding high horsepower, but they wear terribly with some miles.
🪴Retighten the value body bolts.But it also can be a cheap torque converter already in place from a similar problem so you may find the fix but the torque converter needs to be replaced with a oem torque converter.Good Job by the way.🪇

I used it in my 2005 Tahoe with 211000 miles on it and it definitely helped, especially in overdrive. Great video!!

Hey Matt! I'm happy that I won the Lasfit bulbs 🎉🎉 thanks
Send me an email and I’ll get them out to you! Lsxmatt91@gmail.com
Good tip on that tool! I didn’t know one existed for that application.
@lsxmatt, so I understand this video you disconnected the tranmission line from the upper radiator location, then installed a hose to that line and to the 5 gallon bucket? Thanks in advance.
Yes
When my transmission got hot like that in my avalanche, I just change the transmission cooler to tru cool transmission cooler and never had any problems after that
Man was just thinking this morning haven't seen a video from you in a while!
That stuff worked pretty well on my crown vic

Thats actually great to hear😂 It is pretty clunky at times but if its normal thats a relief

Yea that stuff works been using it for years in problem cars. Fords and Nissan's like Bryan said.
Plugged trans cooler can cause it to overheat.
Replaced mine on my Duramax - no issues after that.
My 2010 ESV does that, it stalled at a red light and started right back up, my fluid is pretty dark but doesn’t smell burnt luckily, I also have a code P0011 and thought that maybe related as well..

Awesome fix Matt!!!!
I’ve watched all your Escalade videos today- def some good stuff!
How do you feel about the trans now, I picked up a 172k Yukon xl, debating drain n fill the trans, needs more maintenance but working on it
2014 Silverado put new oem transmission temperature (little block) trans used to get 195f as normal. Now barley gets to 175f
Matt I like your videos I have had good luck 🍀 with shutter fix , fix a Toyota Camry transmission doing same problem with converter !
Tune lockup out of 1st-4th, full lock 5-6 and up the TCC pressure. 6l80 will be bulletproofed. Only way to save a failing factory converter.
Looks like it fixed it for now but im pretty sure the torque converter like you said is on its way out thats another reason for your temperature to climb and will eventually cook the fluid/trans might just be why that fluid was looking pretty black had some of the same issue with my 700r4 how do i know 🤔 😮 in all time will tell
Could it be a torque converter lock up solenoid or something of the sort? Maybe a sticking ball in the valve body?
My Caprice has a slipping converter clutch in the 4L60e, I got a tube of that same stuff on discount just for shits and giggles, and holy hell it actually improved things.
It didn't last though, about a year later it's probably as bad as before, maybe I'll put in another tube of it. Or it's just the TCC actually going out.
Now you just need to change the fluid in the transfer case or did I miss that video?
Its clean so I didn’t bother.
Thanks for the great content.
I just used this in an Acadia after swapping out the fluid. Night and day difference.
We use one of these shutter fix with every rebuild at my shop they do work but they don’t undo the damage that’s been done
Since I still can't drive my Escalade since it needs a tune after putting a new cam, deleting the vvt, duel springs etc: I took advantage to get rid of the crappy torque converter with a circle d 3200 converter and a much bigger trans cooler from mishimoto. Fwi, 6l80es AWD are not fun to take off in a garage setting 😢
Can I drain my 06 Tahoe like you showed?
Not gonna lie and I mean this in a nice way. I was kinda hoping it was going to stall again at the end of the video 😁. Then we could have got a trans rebuild video.😂
Best wishes I really enjoy your channel.
Matt I can’t find your details about the trans friction lube
Hey Matt! I have been experiencing the same issue with my 08 Tahoe with the transmission temp climbing over 200 on random drives. I did a flush as well to see if it resolves it but it did not. Still trying to figure out what is causing it
Walmart has been the best price on all that stuuf for a while now they use to have break clean for $1 and 134a use to be $5
So what temp should the trans be at normally?
180 is apparently normal
Good video!
Is there a link for that cooler line tool?
I’ll add it in a few!
I’m thinking of buying one of these trucks as my 2nd gen got tboned and totaled out. It’s had 3 tranny fluid changes and it is a one owner with 141k miles. It seems to have did some towing.

Why not just replace the torque converter
Why not just replace the Torque Converter. My shutter turned into transmission rebuild after it sent metal shavings throughout
Too many projects right now, I’ll rebuild it eventually.
But… now you have no idea what actually helped. It could be the filter/fluid change, flush or the anti-shutter additive.
The pan was dumped already when the trans line blew off a few months back, the the fluid was sorta changed. Either way the shudder fix is cheap enough I would throw it in anyway.
Billet converter and a good tune seem to be the only true fix for these unfortunately. Even on the gen 5 trucks. They are great at holding high horsepower, but they wear terribly with some miles.
Ok go get a torque converter, and drain the trans fluid, fresh filter and fluid
🪴Retighten the value body bolts.But it also can be a cheap torque converter already in place from a similar problem so you may find the fix but the torque converter needs to be replaced with a oem torque converter.Good Job by the way.🪇
