    Transmission swap/change.

    I hgot aholt of a 93 grand prix with a 3.4 and 4t60-e with les than 80k with a blown headgasket due to a female driver at my disposal thats been sitting for a long time 3-4years - but maintained well before hand.


    and i have my daily driver 95 gtp 3.4 with a 4t60-e with nearing 200k with growing tranny issues with some work done to the engine so extended engine life expected there ... is this a straightforward swap if i drop both kframes (just because i can) and swap the trannys over? and whats the recommendation on which torque convertor to keep/use ? THANKS!!

    The internals of the tranny are different if I remember correctly... 93 is 93 only and 94-95 are interchangeable and 96-97 are interchangeable... I could be wrong

    98 Regal GS - 281k, on the race to 300k
    99 Silverado Z71 - 208k, BGA express
    03 Grand Prix GT - 91k, Britts DD
    99 prizm - 118k, collecting dust

    I do recall the side cover on the 95 is different...if you'll look carefully, you'll see on your '95 there's a mount from the crossmember that actually attaches to the side cover...earlier models did not.

    Not sure if you could simply swap the cover...

    The trans has different internal wiring, but the wiring inside the transmission is swappable according to hollander interchange...

    personally, I would swap the side cover too, if that can be done.... the 93 uses a stamped steel cover with a big metal brace, the 95 has a structural cast aluminum cover with brace that attaches to it's face.
