I just upgraded to a 700r4 from the 350. When I started my 83 c10 the flywheel and torque converter where turning but from the transmission to the axle and the rear end I got no movement. Meaning the axle was not turning, and when I pushed the gas pedal the rear tires did nothing. So did I get screwed on the transmission or was it not installed right. Just at a lost, any ideas or any kind of help is much appreciated.

OOPS I hope you made sure the TQ was all the way in it's all most like three clicks, if not you blow up the pump & you will not move. Bad news you have to take the trans out take it apart take the pump out flush the trans get new tq. Or it might be drive shaft in far enough. But Or your trans clutches are wore out. did the trans work before.
Oh I guessing you checked the Trans oil level and it was OK?
This was the first time this transmission was put in the truck. Like i was saying the flywheel and Torque Converter where spinning but no axle movement or rear wheels. I was bored one day and started messing with the steering wheel and shifter because the steering wheel doesn't fit right. the truck is up on blocks. As I played with the shifter. it sounded like it went into gear and as i pushed in the gas pedal the rear wheels started spinning and the axles was spinning as well. So I took the truck off the blocks and tired again and well it didn't work. The next day I jacked up the rear end and started the truck put it in gear and gave it some gas well it started working for a few seconds then stopped and now I'm at a loss because I don't have the money to take it in the shop.

OK how does your trans dip stick read for oil at the cold level? Did you put any tranny oil in the TQ be for putting in on the trans? Did you rev the motor up to about 1000 RPM for a few min pump the oil and put it throw the gears?
If it does not work after that. The only thing I can say drain the oil in a clean pail pop the pan off check the oil metal specks, then make sure the oil filter pick up did not fall off or there is one in it. if the oil is gritty bad looking then you blow up the pump. The pump is not that bad of a price but to clean out the trans and re place the pump price is up up there 600 to 800. Good luck and let us know what happens.

I am new to this site but have fooled with a number is TH700 Trans. When you installed the trans, the clearance between the flywheel and converter needs to be 1/16 to 1/8 inch to keep the converter at the proper distance inside the front pump in your trans. When you tighten the converter bolts you have to make sure you tighten them evenly so the converter does not pull to one side or the other. If your fluid is full and looks good, see it if will move either forward or backwards. Also, always check the trans fluid HOT on level ground. The TV cable is a life line to these transmission, it sets the line pressure inside the trans and tells it what to do. The adjustment is critical. Usually when one dies out on you it wont do one or the other, VERY rarely will it stop doing both. I hope this helps, TH700's have a bad reputation but are pretty good trans with proper install and maintence. If I can help please let me know. Mike
