    Without being there this is what I'd check.

    Was everything retorqued to the right specs? When I rebuild a trans I use an inch/pound torque wrench on the valve body so I don't overtighten some bolts. Was the gasket for the valve body torn or damaged? It might need to be replaced.

    I'd say you have to take it apart again and carefully inspect it.

    Possibly a new solenoid is defective and sticks when hot. The onlly easy way to check that would be to replace it...Anything else is too scary. The cost of buying a new kit is a pain but if you take it to a shop that's probably something they'll do and then you'll be payng someone else to do it anyway.
