Trans swap

[90chum]

I have a '90 auto and the trans is almost junk, I bought a 4wd 47rh and have the wiring, etc... To put it in, and was planning on a hefty rebuild. But I was on Craigslist and found a 2wd getrag with hydros, not sureif it comes with pedals. So my question is how hard would it be to make the rag 4wd? Or should I stick with the rh?

If you're going to go 5 speed, you'll need the parts to convert the trans to 4WD and either the conversion coupler for the auto t-case, or the hen's teeth hard-to-find 29 spline transfer case.
You'll also need some driveshaft work, too.

Since you're wanting to get away from the 3 speed auto, the options are either expensive or VERY expensive.

With that, the 3 speed can be rebuilt for under a grand, if you don't mind a slow truck.

What would be needed to complete a 727 to 47rh swap?

Driveshaft alterations and moving the cross member. You will also need a 2nd gen adaptor plate and starter. I believe the t-case will work since the 47 has a 23 spline output as well.

Ok, that's what I thought. Thanks.

if you want to do the getrag swap with the 4wd trans, no driveshaft of crossmember mods are necessary.
