With a variety of custom transmission builders and valve bodies in the market. Calibrated Power is here to ensure your financial investment is protected with custom transmission tuning options designed around your builder's spec.

Please Note: The 2019+ RAM equipped with 68RFE Transmissions rolled off the assembly line with a MAJOR flaw over the previous years, "THE UD (Under-Drive) PURGE TEST" is still enabled. Originally designed to keep fluid moving in the under-drive clutch to prevent an airlock, this test serves no usable function after transmission tuning is performed. When adding power and line pressure through TCM tuning this vulnerable factory feature leaves your clutches subject to an extreme dump in pressure which these cluches can not handle. This will ultimately lead to extensive transmission damage. Let us take the guesswork out of it, whether you're just looking to add 30 hp, tossing in a custom Valve body, or getting a fully built trans, our custom tuning comes standard with this feature fixed!
