Would it be possible to fit a TH325-4L transmission to a 368cid with the 4-6-8 ? I guess the tranny itself should fit since the stock tranny is a TH325, but will it prevent the 4-6-8 from working ? And will it be thought enough for the torque the engine produce ? With the current gaz price, I'm thinking more and more about doing that swap.

The only 350 offered in the Seville in '81 was the Olds diesel (standard equip.). The V8-6-4 was optional along with the Buick V6.

I could be wrong but I believe the variable-displacement function worked off the transmission somehow. If I'm not mistaken, to disable the system, people just disconnected a wire from the trans. If that is true, I doubt the trans will work.....there may be other issues too.
