Welcome. Sorry to hear about the trouble. Keep us posted. I had a 2005 ESV and loved it. I think for such a huge vehicle, 160k is pretty good for the transmission...160,000 on 2004 ESV with absolutely no problems...till today. It now "revs up" between shifts and fluid smells slightly burnt. Looks like a rebuild is in my future ($1650)
Fluid level could be lowbelairphil said:i have a 2002 escalade & transmission just felt like it went into neutral while i was on the fwy.. put it in gear & nothing happen,like it went into neutral any idea on what it can be?
I think that might be what I hear on my 03(not sure)Guyz1996deville said:I don't mean to thread jack on the trans discussion but the diff whine you might be hearing guys might be from the prop shaft. I know that there is an update for the prop shaft; for when you get the diff rebuilt..
You could probably just purchase a heavy duty 4L65E that will just bolt up.While my transmission appears to be in great shape (red fluid on dipstick) at 131k, I know it could be time for a rebuild anytime in the next 20k-50k miles. Or maybe it will go another 100k with no issues. Would it be beneficial to look into a 4L80e when the time comes? Looks like 1st gear is taller, but OD is shorter, so it would turn a little bit higher RPM on the highway. Just would need to know if transfer case would bolt up. I might have to get a new drive shaft, but that's not a big deal.
What engine modifications do you have? I only did very slight mods to my engine(iridium spark plugs, MIT air duct w/ AFE filter, synthetic drive train fluids, throttle body coolant bypass) and my Escalade moves from 0-60 faster than most other non-performance grade trucks/SUV on the road. I only had an issue with a BMW X5 50i, Land Rover supercharged,and a Dodge Ram R/T that accelerated quicker than my Escalade from a stand still which is to expected since those trucks as really really quick. Yet, they did not beat me by much considering that I have not even tapped into the power that the LQ9 engine can make with just a few internal mods or even with a tuner.I have a 06 Escalade and after going through 3 transmission in less than 2years, I had to completely upgrade my 4l65e all internals with a stage 3 shift kit instead of converting to 4l80e. The reason I kept blowing transmission was because I have engine upgrades but the main corprut was my rear end gears. Even though I have the factory 373 bolted up to the 14 bolt hybrid axel, my 26inch rims made my ratio more like a 3:30 which was why I keep get the 3 and 4 slip. So I ended up putting in 4:10 and I haven't had any problems. 2018 Escalade cant keep up...lol
Just as I feared. However, as time goes custom controllers would become more popular with the big name tuning companies that would bring the price down for such a swap. LOL, a 6L80 can be had for less than $1000 used and about $2000 new. The real cost is trying to get it to work with my stock set up.Upgrading to a 6L80e would be a serious project. The trans works with the newer 58X Gen 4 engines/controllers. The Gen 3 uses the 24X controller. Anything is possible with $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
