hey ya'll,
i am in the middle of an engine swap from an 89 raider manual tranny to a 91 long wheel monty automatic. The torque converter had to be pulled up with bolts to mate with the flexplate and i believe it has pulled the shaft out of the pump and it won't go into gear. Is there a spacer on the back of the crankshaft i missed on the donor motor? It is a good half inch difference between the two. Both cranks have the same part number so what gives?? Do i need to have one made at the machine shop? Any help would be greatly appreciated.

You have a few issues here:

1. You posted in an Archive.
2. There is an adapter plate between the engine and bell housing, and they are different thicknesses for the stick and auto transmissions. However, they are not 0.5" thick.
3. It does sound like you have a problem with the snout of the trans and that could be that you have not 'screwed' the internals of the torque convertor in properly. There is an installation sequence discussed in the FSM (factory service manual) that you can find at mitsubishilinks.com...remember to drop a small token if you download anything.

Just to add to what Russ said, I once did the exact same swap, from a 5 speed 2door raider to an auto LWB Montero. If you use the adapters that came with the auto, it mates up perfectly.
