Ok, 2001 dodge cummins 4x4 333000 miles. Original transmission. Barely any flakes at transmission oil changes. Driving the truck at 35 mph and 3rd gear. Letting up slightly on throttle it downshifts to second. Takes lots of throttle to kick back into 3rd. Also does the same thing at higher speeds downshifting from od to 3 when going down a hill or letting up on throttle. I assumed it was the gov solenoid and transducer. Changed that with the kit from cassadia transmission on eBay. It didn't change anything. Adjusted tv cable. Didn't change the problem maybe moved the speed slightly as to when it happens. Took it to a shop I trust for them to run it on scan tool. The only thing he noticed was the voltage to the gov pressure sensor never changed voltage. Part 2 of the question is when letting off the throttle rpms go to idle rapidly. Is this normal? Any help or testing ideas would be wonderful. Automatic transmissions baffle me. Give me a engine, and I'm fine but I get easily confused with these and I'm not even blonde. Thank you in advance.
