Thanks for the kind words, folks!
To reiterate what has already been said, the transmission tune is not required to run our engine tunes, but I do highly recommend it. If you buy an ECU-only Accessport, you can purchase the software license to enable TCM tuning at any point - this is done remotely, so no need to ship the Accessport anywhere. The only thing to consider here is that all software licenses sales are final, so there is no return on a remote TCM feature activation.
HOWEVER, if you want to try the TCM tuning and see if it is worth it to you, you could purchase an Accessport new that has ECU and TCM tuning. Install it to your truck and try out the different TCM maps. If you decide that the TCM tuning isn't for you, you can uninstall that Accessport from the ECU and TCM and return it via our 30-day return policy (full refund, but you do pay for return shipping). Then, re-order an Accessport that has ECU-only support. Or, keep the ECU and TCM Accessport if you do like it! Keep in mind that returns need to be processed through the party you purchased the device from - if you purchase through us directly, you would process a return to us; if you purchase through an authorized dealer/Protuner, you would need to process the return through them.
Let us know if you have any other questions!
Thanks,
