bad TCC ???????? or.....

[broncobuckinaround]

feels like im towing a two ton rock. if i touch the brake it goes fine. trans shop, who rebuilt it say they want to do a diag and it 75 an hr if its not the trans.

so anybody who can tell me symtoms of a failing tcc solenoid/switch.

my symptoms are no power, slow shift, 3rd and 4th gear lock in and lock out or shuttle shifting.

Stuck TCC will also give a low or rough idle.

so my torque converter could be bad. but when i or the guys at the shop touch the brake while accelerating it drives normal. what does that mean
