thought I'd btt this and add a little info that i got elsewhere:

If you want to hook up a Toyota transmission to a GM 3.4 V6 or any other engine with the GM 60 degree bellhousing bolt pattern, you need:

Bellhousing from the 87-99 Jeep Wrangler 2.5L. Hooks up to any G series or W series Toyota tranny.

Bellhousing from 96-00 Dodge Dakota 2.5L. Hooks up to any R series Toyota tranny

Also, you can run a 3.4 > 904 auto > dana 300/atlas with no adapters!

just have to use the AMC eagle auto. I believe you can use one of the 904's from a cherokee, but you'd have to swap over some stuff from a cj 904 to mate up a d300

enjoy!
