Need some suggestions. I pulled out my old transmission and am putting in a 700R4. I have the appropriately shortened driveshaft, but can't seem to figure out how to get it in with the transmission in place. I purchased an aluminum driveshaft from a 86 C4, with the little harmonic balancer at the front. This shaft is bigger diameter than the old one, and I had to get a special u-joint at the back.

I removed the driveshaft once before without removing the transmission, but can't remember how I did it.

Any help greatly appreciated :yesnod:

HI

Remove the yoke from the driveline slide it into the transmission then slide the drive line in and hookup the rear then the front.
Any way thats how I do it.

Good Luck

OOPs you are going to have a little difficulty here. The 86 driveshaft is one piece with the yoke assembled. The original 73 had a joke that seperated from the shaft , thus there is no way to put the driveshaft in other than moving either the rearend or the transmission.

i was wanting do a 700r4 swap allso.is the drive shaft from the 86 from a auto or a stick

It's from an auto that had a 700R4 (may not be 86, but that is what I remember).

Does anyone know if there are yokes that I can get for the 700R4 that will work with this drive shaft that have the u-bolts?

I answered my own question. The ones for the Turbo 350 are the same. Just gotta find one.

Maybe you could remove the transmission crossmember, lower the transmission down until the distributor is about to hit the firewall, slide the yoke in, put the U-joint in the differential, then jack the transmission back up and reinstall the crossmember.

Yeah, I tried that. Not even close.

Thanks for the suggestion. I'm going to get one on order today.
