Converter Locking As Soon As I Hit Second

[Boost231]

ok guys got the new motor in cam broken in and decided to take it around the block. well as soon as i hit second the converter locks and the car bogs. so i unplug the connector on the side of the tranny and its fine. so this is what i have done. it was fine when i left the track last year. well i rebuilt the motor and put one of bruces deep pans on it. thats the only thing i have done. anyways i have pulled the connecter out of the trans and did some testing. this is what i have come up with.

Male connector
Pin D did an ohms check on it and nothing volt meter stayed at 1 didnt go to 0 as if it was grounded

Femal Connector
Pin D did an ohms check and it went to 0 so its grounded.

Pin A put 12v to it and it clicks. (if i read this right it should click unless i ground pin D.

Someone else started a thread with this exact title a few days ago. You should find it. I don't think there were a lot of suggestions but something there may help.

As you said, the solenoid should not operate when you put 12V to pin A unless the circuit on pin D is grounded somewhere. The easiest thing to check is to see if your lockup switch circuitry is grounded somewhere. Check it from the ALDL to your switch (assuming you have a lockup switch).

I know you said pin D isn't showing as grounded but that circuit is complete when you give it 12V so one side of the solenoid has to be grounded. Check the wiring in the case if all else fails.

4th gear pressure switch or wiring to the switch may be shorted to ground?

the tcc solenoid is shorted. replace it

forgot to post i found the problem. when i installed my PTS deep pan i pinched the ground wire. all is well now. went ahead and put new pressure switches in a new 700R TCC.
