FM146 tranny bolt to 4.0L?


Yes it's the same bellhousing as the 2.9L. However, the difference in power from a 2.9L to a 4.0L might kill it. If you're going to be swapping in a FM146, I'd just get an M5OD from an Explorer. It's a much stronger tranny and will also bolt up to the 4.0L.
 
yeah, it will bolt up but you will destroy it eventually.
 
bad idea, don't do it.
 
If you baby it, it may last a while but be on the look out for an M5OD.
 
Ya i was thinking of keeping my fm146 still bolted up and slap the 4.0 in for temperary use untill i can find the M5OD

as a second vehicle or a trail truck, it would probably be okay for a while. i wouldnt depend on it as a daily driver though.
 
Ya this is my winter/4x4 rig, I have my car for the summer but i gotta pay it off first.
