Chrysler TCM Flashing
Note: Due to the high volume of TCM orders and the limited stock available, please allow at least a week for your order to be completed. We apologize for the inconvenience. -Team OST
Custom flashed TCMs cannot be returned unless there are extenuating circumstances. However, we do offer three free revisions for any TCM we flash.
A custom-flashed TCM for your NAG1/WA580 equipped Challenger, Charger, 300C, Magnum, or Jeep is the only way to raise WOT shift points, cruising shift points (for larger tires or gear changes) increase shift firmness, and eliminate TCM "limp-mode". For the Jeepers with large tires, TCM flashing becomes a necessity for drive-ability. We offer the option of purchasing a TCM outright through us or sending in your TCM to be flashed. All TCMs include three revisions free of charge.
TCM revisions note: For those sending their TCM to OST Dyno for a reflash or those looking for a revision to their OST Dyno flashed TCM, please include contact information and instructions indicating what changes you would like even if you have already sent your request in an email.
TCM cores MUST be returned within 30 days to receive a core refund. All TCM's are shipped via USPS.
Please send TCMs to the address below:

In order to get the most out of your engine upgrades you need to shift at a higher RPM than the factory or Mopar TCM will allow. Our TCMs are custom-flashed to your WOT shift needs. Simply select your desired WOT shift points from the drop-downs below. Then simply send us your TCM with your name on the box.
