    Good call by you...I don't get 12V at pin 4 of the solenoid even with engine running, and tracing it back I don't get it at the relay or at pin 15 of the TCM. This might also explain why there is no CEL/tranny codes. I wonder if the TCM went first, kid was driving around in 1st and didn't know it, blew up the rear planet, etc.

    Hey could a slightly stipped front planet cause a whine in park and neutral only? If not, what might? Thanks,

    the wining noise could be a loose pump gear -converter -bypass valve stuck did you clean the bypass valve and air test it when apart ?

    This tranny made the same noise when it had a different pump and converter. This is a Frankenstein build...I put a new bypass valve in it. I have no way to air test anything,

    Well it doesn't matter...this thing is toast. Pretty sure something tore loose the first time it tried to upshift. Hitting the yards on 1/2 off sale, found a great donor. Hey, could you confirm this '90 degree' vs. offset converter bolt hole thing...Dacco and everybody else I see shows '96, '97, etc, can have either one, but Dacco catalog shows a note on the 90 degree unit 'EMCC1 grooved friction', which I think was more of an early 2000s thing. Are these catalogs just covering their arses and/or they're lazy? I know my '96 is offset because I did have to spin the converter once to align two holes. I suppose I could grab the flex plate off the donor but cash is extremely tight,

    yes they did have a offset until the late 90 or 2000 units as for the frictions you can use the new design in the early modules it was a upgrade
