FM146 to FM 145

[Beef52751]

I have been considering buying this ranger that needs a tranny, the FM146 is trashed. The owner of the truck bought a FM145 under the impression they would interchange. I have been reading and noticed a FM145 is 2.5 inches shorter, can the FM145 be used with a different driveshaft or some other modifications??? also, what gives the difference in lengths?? Tailshafts, bellhousing, etc???
Thanks

No one?????

I believe the difference in the length is in the main casting of the transmission, not the bellhousing or tailshaft. AllanD could answer in far greater detail.

You'd be a lot better off selling the FM145 for whatever you can get, then putting the money towards an M5OD-R1 (direct swap, more reliable, and still in production).

you will need a longer drive shaft for the rear and a shorter drive shaft for the front...and also have to move your cross member up that 2 inches...there should be holes in the frame for that already...and also make sure that he shifter stick is on the fm145...the 145 and the 146 have diffrent shifters and shifter boots

The transfer case shifter will also be different between the two tranny's, as well as the slave cylinder/hydraulic line.........

+1 on selling the fm145 and looking for an m5od.......

 

[AllanD]

The answer you are looking for is that you cannot juggle pieces to make the FM145 longer to avoid buying driveshafts.

at the OTHER end of the trans however you can swap the bellhousing,
slave cylinder and front bearing retainer to keep the 88-up style slave
cylinder and side connect clutch line.

Personally I'd consider either trans nothing more than a "Core"
for those U-pull-it junkyards that charge a "core" (wanting a dead one back)

i am more interested in the answer to this one also, i am talking to 89dangerranger about his, but if that does not pan out. if these are still in production.

never mind, i have the 145. anyone know bolt up swaps for that one?

the only direct swap is another fm145, but you would be much better off doing what i did and swapping in a mazda trans. you will need a front and rear driveshaft too, as well as both shifters and the clutch hydraulics.
