Revs while shifting
Got my transmission rebuilt in December, no problems with it at all Execpt:
Someones while switching gears, it revs up a little while its inbetween gears (`500rpm). Should i take the car back to the tranny guys(1yearwarrenty)? Or is the problem electrical related? It rarly happens.. About once every 3 drives... thanks,

Couldn't really say, happens durring slower speeds so probably between 2nd and 3rd..
Possibly between 1-2..naw probably not... im pretty sure its 2nd - 3rd gear.

Possible issues:
- TPS out of adjustment - band brake out of adjustment - worn clutch was not replaced

ditto, ditto.
I would place least emphasis on the clutch - not as an expert opinion - just for some reason I think the weak clutch in the Subaru is the high clutch, which means you would first see slip in 3rd to 4th gear changes (or so I believe, but then again I believe in Santa Claus too). The TPS check is easy and only requires a VOM and a safety pin. The band adjustment requires only a 17 and 7mm wrench (but small hands, coupled with a contortionist background couldn't hurt. ) |

What exactly does the TPS do?

The TCU takes the data and sets things like the POWER mode, and changes the shift map, adjusts pressure levels, etc. |
