Just swapped e40d...not working
After blowing my old automatic E40D transmission, I just replaced it. I got a good deal on this new one with only 70k on it out of a working truck. I put in the new transmission, dialed in the torque converter, put on the transfer case, drive trains, filled with fluid to dipstick marker, and filled the transfer case. I put the truck in drive and reverse and nothing happens, but if I rev the engine up to about 3, it will start to grab and move and then it will release and grab again. It does this in 2 high, 4 high and 4 low.

I can't figure out what the problem is, the only thing I notice is the overdrive button no longer does anything, and the trans pan drips a little, but I think that's from the new gasket I put on it.

Anybody have any thoughts on what it could be? Could it be the transfer case?

did you check the fluid level with the truck running in park? sounds like the fluid level is low. if the torque converter was not filled before you installed it, it will take a lot of fluid to refill it after it starts and this leaves little fluid in the pan to run rest of tranny.

Low fluid
The dipstick seems to be wrong as far as fluid level goes. I put a lot more fluid in and now it's running fine. So now I guess I just have to go by feel with how much transmission fluid I need in there.
