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,

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,

$50 tranny is awesome. So far doesn't even seem to need pinion factor/quick relearn, even though I replaced the TCM too. Thanks for all the help,

Resurrecting this as I need to take nickb2's advice and beef up my resources with an ELM327 dongle before chasing my next project. However, there is a major problem with cheap, counterfeit Chinese knock-offs that don't actually contain the ELM327 chip and not only may not work, but could do damage to the vehicle. I see that a company out of Australia called Total Care Diagnostics developed a quality clone of the ELM 327 so they didn't have to pay licensing fees. Apparently it does everything that dongles using the genuine ELM327 chip can do, and it's $37. It certainly seems worth the extra few bucks for peace of mind. Thoughts?
