At what mileage does the 4L60E fail?
I have a 1999 Trans Am with 90K miles. The first thing I did when I bought the car a year ago was change the tranny fluid. It was not burned and there was no material in the pan. It seems to shift fine.
Now I'm getting ready to install a 3200 stall converter, and I'm left wondering if I shouldn't go through the tranny at the same time. I would hate to put an expensive converter into the car, then have the tranny fail and mess up the converter.
I was wondering if there's any consensus on how long these trannys last. The car is staying pretty much stock and won't be taken to the track.
Thanks for your input!

The suggestion about a trans gauge is a good one. If you have a high stall vert, you really need to keep an eye on the oil temp. (it will pay for itself if you catch it getting hot)
Good luck, and you will really enjoy your new performance with the stall converter.

Call TCI and order a rebuild kit with a new set of Heavy Duty clutches & steels.. Also get the heavy duty drum and both billet servos. Then get a TransGo Heavy Duty Shiftkit. That will probly run you $400-$500 dollars if I remember correctly..
There is no point in pulling the trans out and not getting it rebuilt with 90k miles on it. Mine has 110k on it and its taking a **** as we speak.. So, I've already got all the parts sittin here and I'm about to pull it in the next 2 weeks to get it built...

Lost my 3-4 clutches at about 57k miles. I owned the car nearly four years and 25k miles with a lot of 4-2 downshifts, burnouts, donuts, etc but it was near stock for most of that and I kept the temps down once I got the converter/cooler/shift kit/gauge in there.

From Ragtop 99: "Personally, I hate messing with any working tranny. Seems like that half the time, once someone opens one up, the evil spirits creep in."
I'm also of the "if ain't broke, don't fix it" school. You read about plenty of guys rebuilding their 4l60e's three and four times in a row. Your tranny might give up the ghost in 2k or last another 50k. It's not worth trying to save the hassle or cost of R&Ring it if you really don't need to rebuild it in my opinion. It's not that expensive or that big of a job. So, if it's functioning perfectly, I'd leave it alone.
