Product Description
Upgrade your Dodge automatic transmission with the TRANSGO SK 48RE-CV 48RE VALVE BODY CONVERSION KIT, a smart solution for builders and repair shops converting a 46RE or 47RE valve body core into a shift-kitted 48RE valve body. This kit is ideal for 1996-2002 Dodge 5.9L Cummins applications using 46RE/47RE donor cores and is engineered to deliver shorter, cleaner shifts, improved torque capacity, better TCC engagement feel, and stronger overall transmission performance. If your existing 48RE valve body is worn out or hard to source, this TransGo kit offers an economical path to restore drivability and add holding power where work trucks need it most.
This kit is designed around the 48RE platform but requires a qualifying 46RE or 47RE valve body core with a boost tube, 4-land switch valve, and 3/16-inch check ball in the lower casting. TransGo also specifies that you must reuse the vehicle’s original 48RE rooster comb during the conversion. Key benefits include increased line pressure for better holding capacity, reduced converter drain-back, reduced TCC slip or shudder, and protection against common governor pressure sensor issues.

FAQ
What does the TransGo SK 48RE-CV kit actually do?
This kit allows a qualifying 46RE or 47RE valve body core to be converted into a shift-kitted 48RE valve body, giving you stock 48RE-style function with increased line pressure and improved holding capacity.
Is this kit only for 48RE trucks?
The kit is designed around the 48RE valve body setup, but it specifically uses a 46RE or 47RE valve body core for the conversion. That is why it is commonly used in 1996-2002 Dodge Cummins applications with 46RE or 47RE transmissions.
What core requirements does my valve body need to meet?
TransGo specifies that the donor 46RE/47RE core must have a boost tube, a 4-land switch valve, and a 3/16-inch check ball in the lower casting.
Does this kit help with transmission reliability?
Yes. It is designed to reduce TCC slip or shudder, reduce converter drain-back, improve clutch holding power, and help prevent common governor pressure sensor failures.
Do I need any original 48RE parts to complete the conversion?
Yes. TransGo states that you must reuse the vehicle’s original 48RE rooster comb, which is not included in the kit.
