As a child, how would you have known to put down your GI Joes and come wash up for supper without your mother hollering at you from the kitchen when her pot roast was ready? Likewise, how do you expect your overdrive to know when to switch on if the overdrive relay can't send the signal to the solenoid? It can't, which is why AutoAnything is here with factory-fresh replacement overdrive relays to get your system back up and running. When you order your overdrive relay at AutoAnything, you get both our 1-year lower-price guarantee and free shipping.
