I finished my dana 36 to 44 conversion last night. I changed the driveshaft, and the torque arm to a 6m and put my auto yoke on the driveshaft. My problem is that now the car will not move...... (ex... I can crank it and put it in any of the gears, and the car will not move)I will say that it seemed to me that it was in a bind while putting it in. Looking from the rear, when I bolted the torque arm to the rearend and the transmission the rearend was not centered, and I had to pry it towards the drivers side and jack up at the same time to get it to line up(batwing mounts), and even then it was very difficult. I am wondering if the driveshaft is binding in the transmission? I did check the driveshaft before I put it in, and it was about a 1/4 in shorter than the automatic shaft. The transmission worked fine a week ago, and it has been sitting in my garage for a week on jackstands. Could something have stuck in the valvebody due to the incline it was at on the jackstands?

BTW: If I bolted the batwing up , and tried to line the holes for the torque arm up, it would only line up with the bottom holes, and that was with a lot of prying.


:seeya

 

While the car is on jackstands with the trans in neutral and the engine Not Running are you able to turn the driveshaft by hand?

Sounds like it could be transmission related, if you are able turn the drivedshaft by hand

 

It was 12:30 last night when I was going to take a test drive, and found that it would not move, so I called it quits. I am going to work on it again tonight.

 

Gotcha.. check out what I suggested and let us know

 

Perhaps your drivetrain isn't lined up and it's binding (just a guess). When I reinstalled the c-beam I made sure it went into place by hand and all the bolt holes lined up. I used two jacks, one on the trans, one on the diff case. I jacked up the two until the c-beam lined up and the bolts slid in all the way by hand. In the 96 FSM there is an alignment procedure that I followed after I dropped the bolts in.

I pulled the rearend out again, and the driveshaft is too long. Apparently they sent me another auto driveshaft instead of the 6M shaft. It measured 27 1/2 from center of UV to center of UV.

 

Did you remember to take the parking brake off? :lol:

 

I actually checked that....... :lol: I have came to the conclusion that Corvette Salvage sent me the wrong driveshaft. They are going to send me another shaft today. :seeya
