Several weeks ago these codes were thrown up on my 2002 Cavy LS Sport. I read on another post on here about the wiring where it splits off. I've checked and there is bad wires or anything. Few days later everything went away, it was like nothing ever happened. Unfortunately today as I was driving down the highway the car went out of gear then back into gear like it had a mind of its own and threw these codes up once again. Took it to the stealership and they said it was something internal throwing it out of 4th gear and wanted to replace the whole tranny! they said parts and labor 3k i literally laughed in his face. I told them possibly it could be electrical. I'm clueless on whether to believe them that my tranny is fading fast or if this is just a electrical issue. i have 148k miles on it and this car has very well maintained. Any advice? And I've also had that annoying EVAP code thrown in too for past couple years.

All 3 of those solenoids get their power from the same wire. Chances are you blew a fuse or have a break in that wire. The fuse you need to check is the one labeled ERLS in the fuse panel on the left side of the dash. If that checks out, then you need to trace the wire for those solenoids to see if it is broken or shorted. The wire will be pink in color and is labeled as "E" on the transaxle electrical connector.
