Found a sploder for 500 the tranny is bad but thats it. Heard that the motor will bolt up to a 2.9 tranny?
 
Yeah, it will bolt up fine. But the 4.0 typically shreds any tranny (with the exception being the not-so-common M5OD that came behind the 2.9L) that came behind the 2.9.

But, I did run a FM145 behind a 4.0 for a while and it did fine..just be easy on the throttle.

I will be im just gonna run it till i can rebuild that one or get a different one.
I think it should. But there is more to it than that.

Explain..?
 
I thought there was more to what the swap required. Should work good as long as you use a 4.0 clutch.
 
disciplerocks is running an fm146 on a 4.0.....he's wheeled it a few times and it's still holding up.
 
It will bolt up. It will also blow up. Eventually.

The FM's use a weaker bearing design and the torque from the 4.0 beats against them and ruins them quickly.
 
i will just be using it as a temp tranny till i can get the one that goes with the 4.0
 
Wish i could find an explorer for that cheap. Good luck with the swap :icon_thumby:
