Trouble Codes...

I have a 1997 Dodge Caravan SE with a 3.3L with 134,000 miles on it. The service engine soon light stays on now. Doing the ignition switch off-on-off-on-off-on sequence I get 21, 34, and 45 trouble codes. I am not too worried about the 21 since its just the O2 sensor and the light will stay off most of the time with that code alone. I am worried about the 34 and 45 codes as I don't know exactly what would be causing those codes. I took it in for a brake job and had them check the codes and he said that one of em meant that the clutches are getting worn in the transmission, but I just find that kinda hard to believe. He may be correct but I can't note any slipping or anything wrong with the tranny. It shifts very good just like day 1.

Can anyone shed some light on the 34 and 45 codes for me?

My Haynes book sez:
34* An open or shorted condition detected in the Speed Control vacuum or vent solenoid circuits. The * means that the Check Engine light would not be turned on for this.

45** An automatic transmission input DTC has been set in the transission controller (EATX). ** means Check Engine light IS turned on for this. Good luck!

I fixed it....thnx anyway. I just traded for a 2001 Chrysler T&C LXi thats loaded with 3.8L, infinity sound system, leather, etc etc.
