The cost to repair or overhaul your transmission will depend on the condition of your transmission and what type of vehicle you drive. To determine the condition we must first perform our diagnostic pre-check, which includes a full road test and external examination. Most late model vehicles are electronically controlled and itâ€™s possible that the symptom that you feel could be something other than a transmission problem. If that road test indicates an internal problem we may need to scan the computer and/or remove the pan and inspect internally. There may be a diagnostic fee for this service, please contact us to discuss your problem first. We always give you an estimate before we begin any repairs.
