Anything or anywhere I should look or do before I pull my transmission for rebuild? Confirmed torque converter is slipping at lock up. Can I get away with just replacing the converter? I'm not sure if these are known for sending trash through the transmission when they go bad. Any help or opinions appreciated. 142k on my Libby

Isn't it P0740?
It seems like there is a problem with the tcc solenoid circuit.

It may be a problem with the solenoid itself.

Yes, P0740. I'm taking it to a transmission shop to double diagnose. In my scanner it shows slipping and RPMs bounce at 65 mph when it tries to lock up.
