2013+ Ram 2500/3500 HO 6.7L Cummins with Aisin Transmission

The Aisin-equipped Ram 2500/3500 models from 2019 to 2024, powered by the High Output 6.7L Cummins, are well-known for their impressive towing capability. However, many owners report issues with shift quality and timing. Common complaints include delayed shifts, premature short-shifting, excessive defueling, and a generally underwhelming sense of power due to the factory TCM (Transmission Control Module) tuning.

 Custom Aisin TCM Tuning addresses these concerns by:

• Reducing the time between gear changes

• Increasing clutch holding capacity through elevated electronic line pressure

• Delivering smoother, quicker, and more reliable shifts

• Helping the engine stay in the optimal RPM range for improved power delivery and efficiency

The result is a more durable transmission with better performance and drivability.
