Hey y’all, making some headway on the 2002 limited 4.7l 45RFE, has codes p1698, p1899, p0155, p0455. My biggest issue is rough shifting and thuds in gear selection, no start sometimes in park or neutral, slipping and no acceleration all intermittent. So curious when dealing with p1899, I plan to clean the solenoid pack/trs assembly connector, its looks hard to get disconnected though. If that fails do I replace the solenoid pack/trs assembly, and the selector plate? what’s the approach to remedy the code and will it potentially fix code p1698. I’m also a little confused, the range sensor is built into the solenoid pack right? It’s part of the arm that extends off the pack. Any help is appreciated.

Hey @Jmbrooks, that P1899 code paired with the intermittent rough shifting sounds like a real pain to diagnose. You mentioned planning to clean the solenoid pack connector—have you had any luck getting to it yet? Sharing what you find when you get it apart might help others here point you in the right direction
