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 or Mobil 3309 ATF. 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.

Yes, it does. Using a scan tool (not a code reader), you should be able to perform this function. Not doing this will create very harsh engagement and a very sluggish truck. That is because the TCM is going off the previous clutch values from your stock unit - and does not know what to do with the new information. If you are unable to perform this function, please have your truck towed to a shop or dealership that can take care of this for you.
