Product Description
The TransGo RFE-7B-HP Reprogramming Kit is a proven transmission upgrade for 2007.5-2010 Dodge Ram trucks equipped with the 68RFE transmission and 7-check ball valve body. Built to correct common RFE transmission problems, this high-performance kit helps address low line pressure, rough lock-up, TCC slide bang, TCC slip codes, drain-back, limp-in mode, and burnt overdrive frictions caused by added power and heavy use. For diesel owners who tow, tune, or work their trucks hard, this is a smart reliability upgrade that improves clutch holding power and overall transmission control. TransGo states this kit is part of its High Pressure Tuneless Reprogramming Kit line and includes a patent-pending triple valve body separator plate, recalibrated springs, valve body gaskets, PR valve spring, accumulator upgrades, and a new drop-in torque converter limit valve system.

FAQ
What does the TransGo RFE-7B-HP kit fix?
This kit is designed to address common RFE transmission issues including low line pressure, rough lock-up, TCC slide bang, TCC slip codes, converter drain-back, and overdrive clutch durability concerns.
Will this fit every 68RFE transmission?
No. This kit is intended for transmissions with a 7-check ball valve body. TransGo notes that 5-check ball applications require a different kit.
Is this a good upgrade for towing or tuned trucks?
Yes. This kit is a strong option for trucks used in towing, heavy hauling, or higher-power applications because it improves pressure control and helps protect the overdrive clutches.
Does this kit require computer tuning?
No. TransGo markets this as a High Pressure Tuneless reprogramming kit, which is designed to improve hydraulic performance without requiring computer reprogramming.
Why is this kit important on higher-mileage trucks?
Higher-mileage RFE units often develop wear-related hydraulic issues. TransGo specifically notes that worn valve body areas can contribute to trouble codes and performance problems, making valve body correction parts especially important.
