2003 Escalade EXT AWD, Replaced trans with remanufactured transmission at 138,000 miles. Later found it was a transmission fluid leak while pulling a camping trailer that took out the transmission.

Some trends I'm noticing. Light foot and maintenance makes them last a while. And of note, the later models seem to last a bit longer. Did they change something?
I believe they changed in 03 from a 4l60 to a 4l80 but I could have the year wrong

The 4l80s only came in the 2500s.

I have an 05 with a 4l60. I believe the 80s only came in vehicles with the 6.0
hmm, I don't know I guess it could have went in the Denali's but apparently the 4l80 has a lot more history to it than I ever thought it did

Some of the 2002 Denali xl models sporadically had 4l80s. But it wasn’t across the board. I had a client that had one and it was a tank. I think in 2003 only the 2500 models got the 4l80. Which is a shame.
'02 Denali XL 324,926 mi. I bought at 298 and have done cam and heads, and daily do full throttle pulls from a dig past the Ford dealership. I've been doing my own tuning, and my delivered torque has hit 441 ftlbs. There is no way in hell the original sun shell would stand up to that abuse. I've done 2 fluid filters but had to change out my radiator due to trans/coolant mixong and had to change a solenoid another time, so why not was doin fluid anyway.

5.3-Stock 4l60 died at 160k- believe it broke the sunshell on 1-2 shift
5.3 tuned with Jasper reman with no tq mgt 70k miles-1 fluid change
6.0/cam added to same trans with 26-2800 stall went 30k miles before pump let go
6.0/4l85- 3k stall- running for about 15k miles no tq mgt- no sweat
These trucks should have came stock with 80e. So much stronger trans. I'm running a transgo HD kit in mine. It dual feeds it and helps it hold gears better.
