A custom-flashed TCM for your NAG1-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.<\/p>\n

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 a return shipping label<\/strong>, contact information and instructions indicating what changes you would like even if you have already sent your request in an email.<\/p>\n

IMPORTANT<\/strong>– If we receive a TCM with no name, no purchase documentation, no instructions or anyway for us to determine who the TCM belongs to or why it was shipped to us we will hold it for 30 days. After that time the TCM will be considered abandoned.<\/p>\n

Due to the custom programming involved in building these custom flashed TCMs we cannot accept returns. However, we do offer three free revisions for any TCM we flash.<\/p>\n

TCM cores MUST be returned within 30 days to receive a core refund.\u00a0<\/strong><\/p>\n

Please send TCMs to the address below:
\nOST Dyno
\n113 Burns Rd.
\nSlippery Rock, PA 16057<\/p>\n

Properly packaged and labeled Core Return with required information inside:<\/strong><\/p>\n

Jeep Owners<\/strong> – If you have installed a supercharger and\/or tall tires on your Jeep you are probably experiencing some annoying shifting issues: won’t shift out of first, hangs at high RPM in most gears, won’t shift unless you let off the throttle, or shifts at the wrong RPM entirely. A custom flashed TCM (transmission control module) from OST Dyno will cure all these issues.\u00a0Downloadable installation instructions:\u00a0“Jeep JK TCM Install Instructions<\/a>.pdf”<\/p>\n
