I have a 88(I think) dual range transmission with a blown ring and pinion. Instead of buying a new ring and pinion from subaru for $500 I picked up a gently used 93 manual push button transmission($100) with the intention of taking the ring and pinion out of that. The transmission is perfectly fine except that I would be better off with the dual range on my rig. So my question is, would it be possible to just swap the transfer case on the end of the transmission? They seem to be the same size, and it would make the project much easier.

 

 

Thanks for the help.

And just for kicks I have an 88 Gl-10 4" lift ej22 swap

1st thing to do is look up the final drive gear ratios of both.

The gear reduction in a dual range transmission happens in the input shaft between the clutch and the 5spd gears. It's in the front of the case right above the front differential. The single range trans just has a solid input shaft all the way through, and the case is not machined for the dual range reduction gears. The rear transfer case section is the same between the two of them.

 

So you have to put the ring and pinion from the single range into the dual range case to be able to keep the low gears.
