Unfortunately, due to the encryption in the TCM, we are unable to modify shift points for the Aisin transmissions. Our shifts will be firmer and with a stronger lock up, but shift timing can not be improved.

We recommend the Mopar ASRC fluid. You can obtain the fluid and filters here on our website, under 'Service Kits'.

This is a loaded question. While the answer is technically no, it can be done. However, it requires a tremendous amount of work. You would have to source a donor truck that had an Aisin, extract the full harness, ecm, tcm, transfer case, etc. This is a big undertaking and a job that we will not perform.
