Hey forum members I need assistance in locating a transponder, I lost it at Auto Club Speedway in Fontana on the 23rd. I will be billed 400.00 if it's not located I'm pretty sure it's was on the track somewhere. I rather not pay 400.00 for a used transponder if anyone knows where I can get one for less please let advise me. The replacement needs to be a TranX amb 260 Rechargeable Transponder.
