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).
