I have a 1987 244 in my garage with a bad M47 transmission. I have two M46 trannys on the floor. I would like to make one of them fit. One is from a 740 the other from an 84 240. (My local junkyard crushed a perfectly good 88 245 last week!) I think I can work out the electrical part, but wonder if anyone has done such a job before. Some questions I have right off are: Will the driveshaft bolt up? If I change the clutch plate to a M46 will the rest of it be it be the same? Will it mount up the same? I read the posts on moving the throw-out ball and hope everything from the 740 will otherwise work. Let me know if you think I am crazy, I can handle it!

A couple of things, not necessarily all, the driveshaft front section will have to be changed to the m46 type, and the M47 flywheel is the stepped big one of the intercooled turbo 240s. Obviously the 240Ts run M46 with the same flywheel, but the pressure plate and disc must match the two pieces as well. It would not be a problem to order the intercooled turbo clutch kit, but I just am not sure if the M47 clutch kit will go well with the M46. It might but I do not have info on that.

Hey Thanks,

I have finally found a good used M47 for $200, and it looks like that makes more sense. At first all the ones I found were going for over $500! Thanks for letting me know that the project was going to need more than I had to complete. Have a good one.
