anybody selling these anymore. mine is starting to fail on my 80. a little cotact cleaner sprayed in it and it will work for a while. most people do away with the lock up but i think it works pretty well.
i did not call to see if these are still available.. but it took some time to sort out part numberAZ duralast or Wells SW7011Napa TCL101. should get you the proper or really close to the proper setting for your 1980 C3. with a TH350C transmission..please... you might also want to check the 2 brake switches on the pedal bracket..one set of contacts is for the cruise control one set of contacts is for the brake lightsone set of contacts is for the TCC interupt when you step on the brake pedal..on an 80.. the cruise control might be a vacuum hose control valve... that would leave the double sets of contacts on the brake light switch for the brake lights and the TCC interrupt..those contacts can also make your TCC intermittent.. the brake light switch with cruise control is an AZ DR497
thanks wayne p, i did put my switch on a meter and it did have resistance which it should not have any.i have talked to you before about my cruise control, had a diff password at the time (x747944) which for some reason will not work. any how that came to be my transducer. thanks for the info
