2014 Mazda 3 I was wondering what the cheapest option is?is it sending my TCM in for repair and you sending it back or is it to exchange mine for a new one.if I do send my in for and exchange can I pay for shipping and send it in early so I don't have to pay core charge.
The repair is the cheapest option as the firmware update is optional [$99.99] but for exchanges is required. Both are about 2-3 business day turnaround times. If you decide to do the exchange we give you a label to send the core back to us. For the repair, payment isnt required until services are complete, whereas the exchange payment is required up front. The option is up to you.
