Product Description
Upgrade your Dodge automatic transmission with the TRANSGO TFOD-3 REPROGRAMMING KIT, a proven performance valve body upgrade for 1989-2002 Dodge Ram applications using the A518, 46RH, 46RE, A618, 47RH, and 47RE transmissions. This kit is built for drivers who want harder shifts, better clutch holding power, improved manual control, and stronger transmission performance under load. Whether you are towing, racing, sled pulling, or building a street and strip diesel, the TFOD-3 helps reduce slip, improve shift feel, and deliver more positive gear changes in demanding use.
TransGo identifies the TFOD-3 as a Reprogramming Kit for 1988-2003 Dodge, Ram, and Jeep applications with both small-case and big-case TF overdrive transmissions, while also noting it does not fit 48RE transmissions or certain 2003 Dodge trucks with the 8th VIN digit of C. Transgo markets this kit for 1989-2002 Dodge/Chrysler applications, which aligns well for diesel-focused Dodge Ram product targeting. Installation notes from TransGo indicate transmission removal is necessary for installation.
