need to change the trans

[stomper97]

I recently had the truck stuck and the trans filled with mud then I had to drive it 1:30 min home cause the jeep I was with blew two ring gear bolts out the rear cover and he needed the trailer well I changed the fluid but the damage is done and now it wines real bad and is shifting like crap so what i would like to know is if you can put a 3.0l trans on a 4.0l I do alot of 4wheeling and would like the lower first gear but couldnt find any thing on the tech library if 3.0l trans would work.
any input would be great
Thanks
97 4.0l with a manual

The bellhousing pattern is different. The parts from the 3.0 trans will fit the 4.0 trans though.
