I have a 1970 Pontiac 350 with 4bbl, that was originally a 2bbl from the factory. I do NOT have AC, should I still have an idle stop solenoid? Also, I understand there may be some electronic switch that connects to the transmission to aid in shifting over and above the vacuum, is this correct? I have a turbhydramatic trans. Thank you!

Is it ok to not have the TCS system? The car runs ok, never kicks down from 3 to 1, will do 3 to 2 for passing. Also, has a hard time idling in gear. Any of these issues sound like they could be a result of not having the TCS? Thank you!
