It's amazing how much this little part can effect our trucks (and vans).
I've had this truck a little shy of a year and it's run great but steadily it's been having shifting issues ie hard 2nd gear shifts, miss shifts, occasional unlocks at cruising speeds, etc, but not all the time. Sometimes it'll drive like a hack hammer and others smooth as buttah so I figured it was electrical and not mechanical. Did a bunch of reading on this forum and ruled out the usual suspects, vss was within spec, solenoids were within spec, cleaned all connectors at the transmission, etc. Came down to the psom or fipl. The fipl was reading within range at 1.25 idle but figured I'd clean the connection. Went to pull it off and the fipl literally disintegrated in my hands, just physically separated into a bazillion pieces. The inside contact pads clearly had arcing and the connector fingers were mad corroded. Slapped a new one on and it was reading 1.38 where the previous filp was sitting at so the old one must have really been messed up. Reset to 1.20 and she's smooth as glass now. It's crazy how such a little item can cause so much headache.
