How reliable? 4T60 with 200,000 kms (120,000) Mile approx

As some of you know, I am going to look at a 95' Cutlass Coupe w/3.4. I am pretty sure they came with the 4T60. Hoping that the tranny fluid/filter has been changed at least once, whats the life expectancy of these tranny's??

4t60E and some last 20 miles, some over 300k. Really depends on how bad they've been beaten. I play on blowing mine up proptly with I put my GP back on the road.

 

Put a tranny cooler in and change the fluid, bout all ya can do

200,000 miles+ is easy as long as you keep proper maintenance.

im sitting at 196000 Miles with that exact same motor and trans.. and lord knows i beat the hell out of it. im hopeing to see 200k + and by the looks of it. its well on its way.

 

asside from sometimes slightly ruff 1-2 shift its ok aslong as you dont fead 50 more hp to it.

Awesome! Looks like they hold up pretty well. Well sonyman, it's good to see that your e-brake is working well too.
