A few weeks ago the tranny gear indicator on the dash started acting up. Mostly showed 3 no matter what gear I was in. Eventually would move to D (the actual gear I was in). Sometimes it would just jump all around, stop, then jump around ...

Then one day the tranny seemed to be shifting back and forth between D and 3, but I wasn't sure because the tach didn't seem to change with it.

This morn the tranny stayed in 3 the whole way to work (so did the dash indicator) even tho the shifter was in D.

Anyone seen this before?
The tranny ECM maybe?

I'm searching my FSM CD to see if the dash indicator is driven by the tranny ECM or the shifter switch, as it may be a clue.
