Yes, a complete rebuild was completed. All seals, gaskets, o-rings, frictions, steels, bushings, and bearings were replaced. I did air check all clutch packs before final assembly. I did not derermine what caused the origional shudder problem, but it does not exist now. I did check line pressure prior to the rebuild and it appeared to be up to spec in all my tests. There were no DTC's prior to the rebuild and there are none now. I did also replace the manifold pressure switch. I have back probed the harness connector and tested both shift solenoids, manifold pressure switch, PCS solenoid, and trans temp sender. Everything passes the tests I have performed. The PCM does not seem to be aware of any issues at all.
