buick tranny
my mom may have to replace her tranny in her buick so I was wondering if a tranny from my old car (oldsmobile) would fit in it.
its an 1997 oldsmobile eighty eight and fit into her car a 1999 buick Lasabre.
My olds went it the ditch at 40mph and ruined the frame and right a arm so hope can get some use out of it and save mom some $$ and hope the tranny wasn't damaged, it does run...
thanks!

The 99 Lesabre will have the 4t65e transmission and the 97 olds might still have the 4t60e What you need to do is look at the RPO codes on both cars and compare the codes for compatibility. The transmission model code will start with the letter M and the final drive will start with a U if i remember correctly. Here a couple of links I hope will help ID your transmissions.

I did have a get a rebuilt tranny for the olds about 2 yrs ago, not sure if that makes a difference, it sounds like the 4t60 and 4t65 are very similar tho I know it all depends of if lines up the same... still hoping its not her tranny tho and it something else causing high rpms. :*

ok, will look if need be. thanks for that tip. and well she had it looked at today by another mechanic that does more with tranny'* and they are pretty sure its not the tranny that is causing her to have high RPMs and not go into overdrive. they checked her tranny fluid and it'* on the brownish side so they are going to do a flush and look at the o2 sensors.....
