Hi All, Can anybody tell me which solenoid controls the torque converter lock up, tranny won't shift into overdrive.

Or any other ideas why it won't go into overdrive.

Thank you in advance Lou

Explain what you mean with overdrive. Mostly with overdrive ppl mean the last fuel saving gear. But it also has a meaning to tell the engine to rev higher and not shift so fast.
Meaningful if you have trailers and hills. This is why you have 1 2 3 on the gearbox.
