Other than the springs for the retainer plates…Are there any bearings or springs that can fallout when i remove the upper casting from the lower casting? Im about to do this. We are getting p0843 code and p2727. Its making me think theres a restriction at the PS1
Hello there @takeoverjupiter!
To answer your question, there will be 4 accumulator cups and springs located under the solenoid retaining brackets. Other than that, there are no loose parts. Now for the P0843, make sure to remove the solenoids and check the trim valve springs. They should be updated to yellow springs. P0843 is a common code that occurs when the trim springs break. Updated yellow springs will be included in the control module seal and gasket kit. Inspect the trim valves carefully if the springs are broke. There may be damage to the valves. Valves are not included in the gasket kit and would need to be ordered separately.
Thank you for watching our content!
@@WellerTruckParts thank you for the advice! I’ll definitely look into that
Glad we could help!
@@WellerTruckPartsso our springs weren’t broken but I’ve updated them to the yellow ones. had 3 pink & 1 white in it before change. About to put it all back together. So far I’m starting to think maybe it’s an issue with the wiring harness or the TCM. We aren’t able to shift with the electronic shifter at all.
Hello again @Takeoverjupiter
It is recommended that the pressure switch be changed. The part number is 29552364. Before bolting everything together, plug the switch into the harness. Measure resistance between pins 19 and 3 at the trans 20 way plug. You should have full continuity. Measure while you depress the button on the switch itself. When the switch is pressurized, it opens so the meter should read out of limit or OL. When switch is released, it should go back to full continuity.
Thanks again for reaching out!
