2013-2024 Cummins Aisin AS69RC Peakside EFI Live TCM Tuning

Peakside Performance Aisin AS69RC transmission tuning for EFI Live on 2013-2024 Ram trucks with the 6.7L Cummins. Peakside rebuilt the shift schedule to suit a tuned Cummins: upshifts are raised through light and mid throttle so the engine stays in its power band, and downshifts are matched so the truck responds to your foot instead of lugging.

It pairs with any Peakside engine tune, runs on its own, and can be combined with another company's ECM tuning if needed.
