727 Locked up while driving causes?

So after you shut the engine off you still were not able to push the car until you removed the driveshaft? But now it works?

Shutting off the engine and putting the shifter in neutral did nothing to unlock the rear tires, so it got removed. turning the engine by hand at the harmonic balancer while in gears causes the remaining upper ujoint and shaft coming out of the transmission to move. I did not want to run the car in gear with the drive shaft out , but i assumed if it would spin by hand then I would be fine.

Did you install the shifter yourself, or buy the car set up? Do you have headers,or exhaust manifolds? Is the cable outside color red, or black? Is it routed near pipes ,or in a crazy non loop setup? Aftermarket shifter cables, are very touchyupon setup. My thoughts....

The shifter has a red cable going from the B&M to the trans and I have headman headers on the car. Not sure on what you mean by a loop setup?

Lol trying to give yall the needed info so bear with me, I had no idea what all to provide. If pics wind up being needed, they will have to wait till morning as it is very dark now
