I'm working with a 91 4X4 4 cylinder 5 speed. needs a transmission. It's a W trans


I have a couple 5 speeds from 90 - 95 4 runners that were 6 cylinder - manuals.


Can I run the 6 cyl trans in the 4 cyl truck, swap bell housings and transfer cases?

1. are they a direct bolt in?

2. are the gear ratios different, if so by how much.


Thanks in advance.

I believe you can swap bell housings. Not so for transfer cases(different spline count on transmission output shaft). So, you may be able to use the 6 cyl combo together, but it might also require relocating the transfer case crossmember. Shifters might not be in the right place either.

1. Nope, obviously.

2. Yep, see HERE for gearing ratios of W and R(6 cyl) transmissions.

Yer welcome!

Thank you!, more trouble than it's worth for this customer, the correct used and rebuilt trannys are plentyful enough, fabbin isn't nessicary.

I really appreciate it!, I can't remember what i used to do before the internet/forums - oh ya, work a lot harder.

No problem, and wise decision I might add.

Oh...and I forgot about the driveshaft incapatibility too. 4 cyl shafts no bolt to 6 cyl transfer cases most of the time(different bolt hole patterns). Not to mention the shaft lengths not being equal. An extra big headache enlargement (or hole in pocket) for those who dare try.
