What does a reverse servo piston do?

The reverse servo piston is a crucial component within your automatic transmission. When you shift into reverse, hydraulic pressure acts on this piston, which in turn actuates the reverse band, engaging the gear.

Why upgrade to a billet servo piston?

Upgrading to a billet servo piston, like this one from ATS Diesel, offers improved strength over the stock cast piston. This helps prevent failure under high stress and ensures more consistent and reliable reverse gear engagement, especially for trucks used for towing or hauling.

Does this kit include everything needed for installation?

This kit includes the billet reverse servo piston itself. Installation will require transmission disassembly, and you should refer to the manufacturer's instructions or a qualified mechanic for specific installation procedures and any additional seals or components that may be needed.

Product Details

This kit includes the billet reverse servo piston for your 1996-2007 Dodge 5.9L Cummins with a 47RE or 48RE transmission. This part is key to engaging your reverse gear smoothly and reliably. If you've noticed a soft or delayed engagement when shifting into reverse, or if you're looking to build a transmission that can handle more power, this billet piston is a solid upgrade.

The billet aluminum construction makes this piston stronger and more durable than the stock cast part. This improved strength helps prevent the piston from cracking or deforming under stress, which can lead to performance issues or transmission damage. A stronger servo piston means more consistent and positive engagement of your reverse gear, especially important when towing or under heavy load.
