Just want to make sure I'm troubleshooting this right. Car will stay in drive when coming to a stop. torque converter doesnt seem to be unlocking. When running down the road normal passing acceleration unlocks the converter or at full throttle. However when I step on the brake it does not unlock. I am assuming the tcc solenoid is bad. Also if I am at about 10mph and the engine is lugging a quick snap of the throttle to the floor unlocks the torque converter and shifts it into 1st gear. Only does this after about 20 minutes of run time, when cold it works great.
