Help my tranny is about to go and i want to know if i can bolt my other 45re tranny in replace of the original 46re until its finished getting rebuilt how long will the 45 hold up behind that 5.9 360 motor , i have a 2001 dodge ram 1500 light duty laramie ...

 

WTF is a 45RE?

44RH/RE and 46RH/RE are generally what's found in the 1500/2500 5.2 and 5.9L motors (automatic's anyway).

If indeed you are referring to bolting a 44RE up to a 5.9L, it may hold up for a short time period.

Bell housing the same?

 

Yes it is a 44re you turd lol .. Ok but can i put that tranny up in there no problemo ? Or does the drive shaft have to be longer?

 

I'm not sure how the physical size of the 2 differs, could take a little extra work to make it fit.

How long will the 46RE be down for rebuild?

 

I don't think it will fit at all

 

44 supposedly mount right up but the tail is shorter from what i am hearing..

 

Yep, 44 is a shorter trans, needing a longer driveshaft.

 

How much shorter is a 44RE than a 46RE? This is the first time I have heard of this. So when I swap my 44RE for a 46RE I am going to have to get my drive shafts modified?? That will suck................................

 

About 4 inches from what I can determine.

 

There is a 45RFE, but it is a completely different beast than the 46RE, isn't it?
