I took the car to the local transmission shop complaining that the torque converter in my tmh3t40 trans wasnt locking up. So after a total rebuild all interior parts valve body,tcc switch,torque converter, still no lockup. When you run a diagnostics on the computer it says the converter is locking up at around 50 mph,but it is not. Please help $1.600 in the hole.

what makes yo think its not going into lock up? the only thing i can think of is a speed sensor, bad ecm, or bad wiring. The tranny is telling the computer to lock up but if the wire going back is open it wont lock up. good luck

Bad Solenoid -- it's under the pan facing the driver's side fenderwell..
