mine is at 131k....still shifts great but really heats up when put in OD(past year or so)..i had the fluid/filter changed and after a few weeks it had a odd smell/burnt color...i may add an external cooler eventually..esp. being in the south and all...i really feel the tranny will go long before then engine...

I would definately add an external cooler in your case. Heating up is very bad for the longevity of a trans.

VigCS,

Forgive me for milking your thread; but does anyone know which transmission is in a 2000 LeSabre?

Mac...shame on you..lol
Probably a better question in it's own General or lounge topic. If it's not a 460 it won't see much exposure here.

4T65E.

Just for the record I pretty sure me 92 se has the orinigal tranmission still going strong mine car has 171000 miles on the clock. I mean to ever once awhile, but mostly baby it and change the tranmission fluid every 30,000 miles. Like the manual recommends I figure that gm most know what the car needs
