SRT STAGE I 66RFE valve body

  • Billet Valve Body Channel Plate
  • Channel plate which is cut from a solid 1” thick piece of billet aluminum.
  • Shallow hydraulic circuits in conjunction with thicker body allows a very rigid alternative to the OEM channel plate which is prone to warpage & cross leaks due to its thin weak design.
  • Transmission Spin On Filter Screw, Billet Steel
  • Billet Steel screw replaces the factory plastic style screw
  • Accumulator plate made from stronger, thicker material to prevent flexing
  • Three additional mounting holes and high torque-rated screws prevent the plate or screws from coming loose from normal vibration
  • Specially graded tap provides higher torque yield threads
  • Accumulator Piston Kit
  • Dual-guide seals prevent piston-to-bore scuffing
  • Updated seal location allows use in scuffed bores
  • Prevents transmission failure from broken plastic pistons
  • Drop-in Zip Valve™ parts install quickly and easily
  • Accumulator plate made from stronger, thicker material to prevent flexing
  • Three additional mounting holes and high torque-rated screws prevent the plate or screws from coming loose from normal vibration
  • Specially graded tap provides higher torque yield threads

66RFE BUILD PARTS LIST

  • Borg Warner Clutch Set
  • Borg Warner Steel Set
  • Mopar Bonded Pistons
  • Transtec Overhaul Kit
  • Mopar Solenoid Pack & MLPS Cam Plate
  • Mopar Line Pressure Sensor
  • New Pump Gear

  • TransGo
  • Sonnax Solenoid Switch Valve and Plug Kit (Reaming Required)
  • Sonnax TC Limit Valve / Sleeve (Reaming Required)
  • Updated Valve Body Resurfacing

Update Details:

  • Sonnax TC Limit Valve Upgrade: We correct common TC limit valve bore wear with a precision reaming tool and fixture, installing a top-quality Sonnax valve and sleeve for a lasting fix. This prevents reduced converter release pressure that can lead to Torque Converter Clutch failure—a critical update often skipped in standard rebuilds.
  • Sonnax Oversized Solenoid Switch Valve: We address bore wear that causes pressure loss, cross-leakage, and sticking valves by reaming the bore and fitting a Sonnax oversized switch valve kit. This permanent solution stops fail-safe mode, error codes, bind-ups, and clutch failure in their tracks.
  • TransGo Overdrive Pressure Plate: This hot-forged 1045 steel plate, fully CNC-machined, boosts a 15% increased overdrive clutch capacity effortlessly. It adds space for two extra single-sided clutches, enhancing durability across all models.
  • Valve Body Resurfacing: We meticulously resurface both valve body channel plates to eliminate warpage and fix subpar factory machining. This extends transmission life and prevents hydraulic cross-leaks that trigger common rationality codes and premature clutch wear.

Needed a transmission for my dodge 5500. They shipped it quickly to my mechanic then let me bring the core in since I was going to be in the area, so I didn’t have to spend a bunch on shipping to get my core deposit back! Molly is the best to deal with! Can’t go wrong with them!

The owner was very involved with my 4l80e swap. Had an internal harness connector o-ring leak they helped me resolve to prevent fluid from leaching up into the main input harness. After that the trans performed flawlessly. Great communications and shipping crate professionally done. I will use them again I am sure. I would proudly wear a shirt or hat with their logo. Thanks team.
