3.0L to 4.0L?

[Ryan_1313]

so im pretty new to this whole scene and got some questions, my 3.0 bugs me and i found a good deal on a 4.0, the only questions i have is; Would i have to replace the transmission and rear gear the back end as well? Or does the transmission i have work?

the axle can stay. the transmission has to go.

so if its possible get the transmission from the same truck as the motor im assuming? or at least get a tranny out of a 4.0 truck?

any 4.0 OHV transmission will work. youll also need the engine wiring harness, PCM, belt driven accessories, etc.
