240 Dumb transmission question

CAPT_BLOTTO · 09-26-2019, 02:39 PM

I have an AW71 that I believe is from a 940 but it may have been swapped. I don't know all the history of it. I put it in my 92 240 and was buttoning everything up. The driveshaft seems to be a little short. Maybe it was late and I'm just crazy. But would a 940 have a different tailshaft length than a 240? If so I should be able to just swap housings right?

The drive shaft is a different length. You need the drive shaft from the 240, complete 2 piece setup.

Or at least the front half of the drive line from a 240.

CAPT_BLOTTO · 09-26-2019, 11:24 PM

Well I’m using the drive shaft that was already in my 240. Which had an automatic.

That makes no sense at all, all AW70/AW71/AW72's are the same length.

Any pictures of the trans out of the car? did you take the DS off the car at all during this swap?

CAPT_BLOTTO · 09-27-2019, 09:09 AM

That's what I thought but maybe I didn't know if there was some weird late change other than the bushing bearing change. Driveshaft was just unbolted from the trans. And I don't think you can put the mount bracket on wrong. I'll take another look. I'm sure its just me.

They are absolutely the same length. It’s something you are doing wrong.

Okay, I'll ask... is it (allegedly) a foot short, or 1/16"?

John242Ti · 09-28-2019, 02:18 PM

There's no chance that this may've been an Aw55 or a Bw55? That's about the only way it'd be shorter.

I keep re-reading this and am still puzzled... wha happen???

MasterBlaster · 09-29-2019, 05:13 PM

Well... the driveshaft is 2 pieces (otherwise there's no way to replace the center bearing), connected with a splined section. Any chance it was compressed when removing, and the skanky old spline grease is sticky and doesn't want to let it re-extend?

Hmmmm..... OP has a sh!tty old 240 that he pulled an automagique out of....

Fifty cents in a bet says the engine mounts are junk as either they have just been replaced or are broken.

CAPT_BLOTTO · 09-30-2019, 09:57 AM

Actually engine mounts are brand new. I tried it again this weekend and it was fine. I think the other day it was just late and in the dark, and my tired brain got the best of me. It bolted up fine this weekend.
