New TCI Streetfighter won‘t shift in 3rd when hot

That's disgusting. To think of all the trouble caused by some fool's apathy. I found a similar situation in a TCI trans; workers don't care. That trans wasn't even air pressure tested. It would have failed miserably. Test each drum on the pump mounted in a vise; then test again after the drums and pump are installed into the case. Only takes about 50 pounds.
