2WD vs. 4WD M50D-R1

[atomicjoe23]

I have a 4WD '99 4.0L OHV Ranger with the M50D-R1 5-spd. manual that has lost 5th gear and I have found a low-mileage M50D-R1 out of an '01 3.0L Ranger for a good price. . .only problem is the 3.0L is a 2WD model.

Question is. . .what needs to be done to change the 2WD transmission to a 4WD transmission beside changing the tailshaft housing?

I can remove my tailshaft housing and bolt it on the "new" transmission, but I don't know if the output shafts are the same or need to be changed or how much work that involves.

Thanks for the help!

This might be simpler than you think. If you are only missing 5th gear everything for 5th/Reverse is accessible by removing just the tail housing. and removing the hardware back there.

adsm08. . .any idea where I could purchase a new 5th/reverse assembly to repair my transmission???

Besides scouring junkyards and pulling it out of a transmission I don't have the first clue as to where to start looking for a part like that.

Thanks.

Is there a better service manual for these transmissions than the Chilton's or Hayne's manuals?

Thanks for the link to Cobra Transmissions adsm08. . .they have pretty much everything and parts are pretty reasonably priced to (in my opinion and experience anyway). . .
