Yeah - had to be a fluke. Problems never 'go away' otherwise...

I'm gonna' get a vid of the singing TPS, and try to get feedback from TCI and RPM Transmissions.

I'm not exactly sure of what you mean by "singing ckt TPS". Are you hearing something or reading something electrically near the trans?

Yep - as the TPS goes range of motion, something in the tranny buzzes. Pitch changes in the buzz, as the TPS arm swings. ONLY Closed Loop too - has something to do with some circuit gettin' energized in CL.

When I un-hook the power to the tranny control module, it does NOT happen.

The shop that did the tranny said it was probably a shielding issue, related to Fluid Pressure Solenoid. Pffft. SOMEthing in the install in not 100% correct, but again, no trouble codes in the programmable tranny controller. It even calibrates for 0% TO, and 100% TO, in it's own Setup Wizard, on the handheld interface for the controller.




Probably time to let this thread drop; maybe resume the 'Hesitation' thread 1990 Throttle Hesitation, FROM which Darryl chopped off for THIS thread... Top end is done - pretty sure it's done right (except for getting the TB to Marc, and re-installed).
