Well I have toasted my second 4r100. I have a 2001 ford expedition with a 5.4 4x4. I want to put a five speed in my truck. I had been under the impression that they did not make a f-150 with a 5.4 5 speed. But during my research I found a 2002 with that configuration. I had been thinking that I would buy a used 5 speed out of an f-250 4x4 with the 5.4. What I need to know is if my transfer case will bolt onto the super duty tailshaft or if I need to start researching using a trans out of a f-150. Any and all information will be appreciated.
Thank you GLC I realize that. What I need to know is the difference between a super duty manual shift transfer case and a f-150 manual shift transfer case. Do they have the same bolt pattern and are they interchangable?
Are those transmissions really that weak? I would hate to put a body lift on this truck, but I might be open to a little carving on the floor boards. So the question still remains. Will an expedition transfer case bolt onto a super duty transmission? Output shaft spline count, bolt configuration, etc.
I'm afraid I don't have that info, sorry. I'd hate to guess and mislead you. However I do know that a M5OD-R2 is a light duty transmission that doesn't hold up to anything much stronger than a stock 4.6. We have a member (JMC) that put a blown 5.4 into his truck that came with a 4.6 5 speed, and he's now on his 5th tranny. The weak spot is the input shaft. I think he said that when this one goes, it's getting a ZF.

"the 5 speed was never made for the Triton bellhousing. "
Are you sure about that? I have found several for sale. I believe that I read that they were mounted to both 5.4's and in V-10 triton motors (same bolt pattern) in super duties. I did find that the output shafts of the zf5 are 31 splines. I will go tomorrow and count the splines on the first 4r100 I toasted. This is starting to look as if it may be a doable project. The real problem will be explaining to the wife why I had to take out the center console and cut a big hole in the floor.
I had those dimensions a long time ago but I have misplaced them. I would not use them to calculate driveshaft size. I would measure instead. Remove the driveshafts in the current set up and measure flange to flange or flange to output shaft end. Once the new set up is in measure again. The difference is what you add or subtract. Note if the first measurement is bigger then you shorten the shaft. If the first measurement is smaller you lengthen the shaft.
