Should have written out vp44 instead of ppump. not sure of brand lift pump but it is mounted on the frame under the bed and I haven't checked the pressure. The edge has a low pressure alarm and it has only alarmed once after a filter change where I used a different filter (not cummins) that was denser material. The alarm is set for below 10 psi . Update to post. I cleaned up all grounds removed add-on accessory ground connections to test the alternator. I need a better Multimeter. Klein meter has vac~ . Showed 028 whether reading at alternator or battery. I will pick up a better meter.

I replaced my VP44 pump using the procedure laid out by Mopar1973man. Thanks for that. After just joining the forum, AND after reading about the TC/transmission problems due to faulty alternator and grounding issues, I was wondering if the APPS re-learn procedure should be part of the VP44 replacement procedures? I was having an issue with 47re not wanting to kickdown or maybe no throttle response, is a better way to describe it ,after the transmission shifted into 5th gear. It kinda wants to buck when giving it more throttle and has progressed to slowing down on inclines even with peddle to the floor. This morning I removed the Alt fuse and unplugged the field wire to Alternator and symptoms remain the same. Fluid is full and color is fresh in the transmission. No MIL on dash. Next job is to clean and re-tighten all grounds, remove all add-ons (amp, edge, back up leds, tranny cooler fan) and test the Alt.( even though the "test drive" didn't change the issue I should use the meter to verify any anomaly. I hadn't read any posts exactly describing my issue of the tranny shifting through every gear as it should, with plenty of torque and response, but then no response once 5th gear is achieved. It has progressively worsened in the past 4 weeks since the VP44 install. But was doing it before and I just expected it to be the PPump finally failing. The ppump controller death code had been set and check engine on the dash over a year. I will report back after doing the ground maintenance and volt testing. I did the APPS reset yesterday. I have used this forum info for several repairs and diagnosing. I like the fact that most posts and replies to posts aren't a bunch of users writing replies just to be posting, but actual tried it, did it, it worked, real time, real knowledge replies. Hope I can contribute to this sight every now and then. For the most part, my truck has been great and purchased as maybe the last truck I will ever need. I'm tapping this out on my laptop so anybody reading this on a phone is gonna be like."shut-upalready" . Thanks for any insight. (Oh yeah, fuel mileage is really bad. I changed the fuel filter prior to the VP44 job)

Have any of you done your own undercoating and what product did you use? Looks like it would be fairly easy unless you just didn't need it due to being continually bathed in oil. Mine could use it under the floor pan and bed.
