We just picked up a used oo beetle. the overhead temp/clock module is inop. I am a chrysler master tech 10yrs. I checked for power to the conn. there was like 2 or 3 power wires, don'r remember. i don't have a schematic. fuses all ok. Is there any checks for it, is failure common in these. it does nothing not lighting up or anything. Also trans seems to shift quickly into 2nd gear, is there any trans throttle adjustment cables? Thanks for any ideas

Also what type of fluid does to trans take, i thought about doing a flush or filter and fluid change on it?
