Just finished installing the rebuilt 47re for my boss. rebuilt the trany with a napa kit, bought a trans go shift kit (TFOD-HD2) and a hughes towing tc. started it for the first time to check the oil and top it off, and found out it doesnt work. when you put it in any gear, r d 2 1, i feel it "clunk" into gear like usual, but it slips when i try to drive it. so bad that i had to put it into 4lo to get it to move at all. not really sure what i did wrong. any help would be greatly appreciated. i ran the trans thru all the gars slowly several (hundred) times to make sure there was no air in the lines but its still the same.
