SRT STAGE I 68RFE (VEHICLE CANNOT HAVE TRANS TUNING!)

• Sonnax Smart-Tech Overdrive Clutch Housing Kit:
  • Modified housing holds physically larger clutch pack for 20% more clutch capacity
  • 2X Thicker steels and double-sided clutches increase steel mass by 28% for unrivaled heat dissipation
  • Bolt-on anchor plate eliminates clutch pack flexing and distortion that contribute to heat build-up
  • 16% More OD apply area for firmer, more controlled shifts
• 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 Cover Plate Kit
  • Thicker and stronger than stock, also includes 3 additional mounting holes to prevent plate from coming loose.
• TransGo Hi-Capacity Overdrive pressure plate
  • Expands capacity to add two extra clutches.

Updates to the Transmission:

• Updated Sonnax TC Limit Valve
  Severe wear of the TC limit valve bore results in loss of converter release oil pressure. Reduced release pressure at low speed and idle will drag the converter lining, causing engine surge, pulsation or stall.
  Low release pressure at cruise affects and limits efficiency, often increasing RPM and reducing fuel economy. If release pressure is low enough, the converter lining may drag enough to glaze the lining.
  A worn TC limit bore contributes to converter drain back issues. The Sonnax oversized TC limit valve kit 44912-03K restores normal converter charge and cooler flow, correcting converter overheating problems. Installation of this valve requires use of a special reaming fixture and jig that allows this high quality valve and sleeve to be installed.
• Sonnax Oversized Solenoid Switch Valve & Plug Kit
  Solenoid switch valves and plugs in listed Chrysler transmissions cause bore wear as they oscillate and stroke during operation. This wear allows pressure loss and cross-leakage, and often permits the plugs to cock and hang up in the bore. This can result in fail safe mode, various codes, bind-ups, and burnt overdrive or 4th clutches. In 41 and 42 series units, TCC concerns can result, including engine stalling due to improper lockup. Reconditioning the bore and installing Sonnax oversized solenoid switch valve and plug kit 92835-32K restores vital clearances for renewed operation and control.
