What model number is the trans? You will want a .411 or higher.

All trans are rated on torque and geared for power bands. .41x get progressively stronger. Is that a 3.0 or 3.5L? I think with the 3.5 you will want something stronger. They are also very common transmissions, once you do the swap I would keep a spare around JIC.

On the manual 5 speed transmsissions they are all the same. If you have both vehicles close at hand where you can get at the parts you need, it can be done quite simply. The differential might possibly or ideally changed also to give you better gearing then with the automatic diff. Also, it would keep the speedo correct but tire size would have to remain the same or very close. Yes pedals must be change, clutch hydraulics will have to be changed over also. Not really difficult if you have access to all the parts until you finish the job.

Speedo should be unaffected by the switch to five speed as they drive off the tailshaft of the tranny.

No that is not right Tom. It doesn't matter where it is driven from on the tranny. If you change the RA ratio from what the transmission was designed to run with, the speedo will not be correct. Only if the donor and receiving vehicle have the same RA ratio will it be correct.

RA? On the manual 5 speeds what is all the same?

The speedo ratio is based on the rear diff and is unaffected by trans.

RA = Rear Axle

Well, it might work, it might bolt up. But I suspect that there is a big difference in design and a really big difference in flywheel weight. So, it might bolt up and it still might not work, or it might even work and you will find it quite objectional from a "vibes" point of view. The lighter the flywheel, the more you will feel the power pulses at low rpm. Be prepared

Will work just fine, but that 8 or 8.5" clutch wont last very long. Better off getting 9", that will work just fine.

M103 2.6 dual mass flywheel worked just fine behind my OM603.
