your best bet is to email jerry. [email protected]Yes, mine is a 2002 but it was an auto. I'm swapping in a 5 speed out of a 98 amigo 3.2L. My understanding is the AR5 and the MUA5 are quite different units. You are correct in that the MUA T case is integrated into the transmission. However the 2 halves remain separated internally and each have their own oil supply. Here's a pic below of the seal that separates them (t case side).

There's one part of me that's ready to just drill a hole through it, run a screw in it and pull it out. If I could just turn it over I'll see the Part Number. My only fears are 1: what if I drill through the part number (would be just my luck). And 2: what if I can no longer source a new seal (would "also" be just my luck). I'd PM JLEMOND but I'm still too new of a member. I have to make a certain number of posts before I'm allowed to PM people. If you'd be willing to shoot him a PM and send him towards this thread I'd be hugely grateful. Otherwise I'll just keep puttering around and making friends and comments on here until I can PM people 😂
