4L60E transmission

in an lt1 how do they hold up. Are they reliable and strong transmissions.
How many miles should i expect out of mine under normal drving conditions how do you guys like theses transmissions.

My 93 Z28 had, I believe, the 4L60 in it and it was great. No problems through out the time I owned it at about 85,000 miles give or take. My sisters T/A has the 4L69E and it has had no problems and it's around 85,000 miles too. It also has the performance button on it. Much firmer shifts, it's very sporty for an auto. I like them for being an auto, they are responsive in the 4L60E (not the 4L60's) shift nice and smooth when you want it and firm when you need it. I also drove a 95 Z28 with about 140,000 miles and it had a terrible problem with the transmission slipping, had pretty burnt fluid too though. In short they are IMO excellent transmissions, but why an auto, go for the six speed, much much more fun.

where is this performance button that you talk about it

it probably has one of those electronic shift improvers.. i know B&M makes them.. and they only cost like 40 bucks or somethin like that..

Actually think that some TA's came with that performance button from the factory. Ive seen it before it was on the shifter when i saw it.

It is on the center console next to the shift lever, it looks like a stock feature/button, I'v never seen it on a Z28 but I think other pontiacs like the bonneville had the same optional performance shift button on them.

news to me... i guess ya learn somethin new everyday..

I got that performance shift button on my car. It just electonically increases line pressure to deliver firmer shifts. The Z28 already have slightly higher line pressure so it wasn't a big improvement but it also comes with the Corvette Servo if it has the button.

hey Formula.. i might be making a move towards the dark side next spring... looking into a 4th gen Trans Am.. i found an awesome 94 for 6900..

Better have low mileage or thats a bit high but the dark side is sweet

no!!! don't do it!!! j/k

it has 88,000 miles.. which isnt that bad.. it also has 18 by 9.5" chrome rims.. t-tops and leather interior.. all the things i planned on puttin into my car.. and the V8 pretty much sold the deal.. i wish i could upload pics.. because it doesnt wanna work for some strange reason

my 4l60e finally gave up at 170k.. and before that it was good as new still... What did it was a netrual drop at 6000 rpm
