Now you are set up for 4x4! Put a transfer case in and a rear drive shaft out of a 4x4. Good to go!

Yes, it is possible, if that truck had the same engine as your truck.

got the new one torn down to extract the hard parts that I need. Question. Why is the shaft a different length going into the transmission? I expected the part past the parking pawl to be longer but not the other side. The plan going forward is to use the best of the parts and put it all together with the original case. Any info is helpful




edit: I’ve realized my error lmao

The shafts are the same length going into the transmission you have the bottom one turned around. Top is for a 2wd van and bottom is for a 4x4 truck.

you may be 100% right but in my case, both transmissions are 2wd, the bottom one came out of a 450 with the driveshaft brake. Did ford simply use a 4wd transmission and engineer a different tailhousing for the bigger trucks? I really don’t know.

The 450s used the 4X4 transmission with the brake mounted to the tail shaft for the 2 wheel drive trucks. Ford didn't make a 450 4WD version.

Thanks to all those pitching in and helping me. I’m in the process of assembling the transmission, up to the part where you compress the intermediate clutch spring to get the snap ring over the piston. Before I proceed any further I have a snap ring that is bugging me out. It’s about the size of the intermediate clutch and smaller than the ring used to retain the overdrive clutch piston. In other words the ring is smaller than the part I’m up to. It measures just under 9’’... ummm where does this snap ring go?

Update:

I still can’t figure out where the snap ring goes. Going to assemble the “bad” transmission as a core and see if I can’t find a spot for this mystery 9” snap ring

If the transmission has already been rebuilt, it's possible that the center support has been machined due to wear. In that case, the snap ring will go in before the center support.

You are correct Cleatus, Thankyou. The snap ring ( .050”) came from the donor transmission and is not needed for the original case. Mystery solved

Why don't you use the center support from the donor with the snap ring as it is a wear prevention item.

I don’t have an answer for that. I’m going to end up tearing down everything again and reassembling everything anyway to double check before she goes in the truck. At that point I will measure both center supports and see if there is a difference

Use the center support that has been machined for the support ring.. The machined center will not have any lugs. When you install this ring, the gap is to the bottom of the case.

I measured the center supports and again, Cleatus was right. The machined one was roughly 1/16 inch thinner so I used the snap ring to fill up the gap. What do you mean the machined one will not have any lugs?

also I’m installing the pump and it’s being a real PITA. Manual states to use “hand power” to seat the oil pump but I cannot get it to seal in and sit flush after trying several times with transmission fluid as a lubricant. Any suggestions?

Did you disassemble the pump?

Those things can't just be bolted together "close enough". If it's bolted together off-center enough you'll never get it in without brute force and when you do, there go the bushings in the center bore and it will leak when installed and ran. There are tools (commercially available or home-made) to do this.

If you never took the pump apart or used a tool to align the pump halves, you have a stack problem and something is not installed all the way, bottoming out the pump before it's seated in the case. The coast clutch is the hard one if it's not pre-assembled with the overdrive gear assembly. I've never used the tool as it just takes patience putting in the coast clutch drum BEFORE the overdrive clutch plates (reverse of the manual instructions). It really can't be a stack problem aft of the center support or you'd never get that in.
