Fuel pump driver module
im having issues with like a shutter or studder around 55 mph. I'm going 55 and truck is in overdrive, if I give it enlighten gas to speed up but not shift out it starts to like studder, as if it wants to shift out but doesn't. Almost like it's doing it but really fast. Also every now and again when my trucks cold and I start it it's has a rough start, kinda turns over a couple times like regular the start to lope like a dang cam and fire up. FPDM or plugs?

If your FPDM looks good (no corrosion or cracks) use some rubber or fiber washers behind it to somewhat isolate it from the truck frame.
The problem is that the aluminum and steel react and corrode the aluminum.

"Most duct tape is also an electrical conductor." - -The alluminum case back is a heck of a lot more conductive than the tape. The tape is not a full-on stand-off like the spacers, I know. It does separate the metals though.
