Installation Instructions

Description: Dodge trucks pulling heavy loads or boosted to 400-600HP are at a high risk for overdrive burnup due to the stock transmission's insufficient clutch capacity and fragile OE clutches.

Even small amounts of heat and extra torque will push the thin (.034"), single sided clutches over the edge, distorting the clutch pack. The fact is, any distortion of the clutch pack takes the clearance out of spec and makes overdrive clutch burnup inevitable.

Keep hardworking trucks on the road with this Sonnax Smart-Tech Overdrive Housing Kit. The unique billet aluminum housing holds a physically taller clutch pack and increases OD apply area by 16%. Plus, 2X thicker clutches increase clutch pack steel mass by 28% for unrivaled heat dissipation.

This groundbreaking kit is the only top of the line upgrade that eliminates clutch problems without relying on valve body/pump modifications or adding the expense of extra components.

Modified housing holds physically larger clutch pack for 20% more clutch capacity
2X thicker steels and double sided clutch pack increase steel mass by 28% for unrivaled heat dissipation
Bolt-on anchor plate eliminates clutch pack flexing and distortion that contributes to heat build up
16% more OD apply area for firmer, more controlled shifts
Combine with Sonnax Line Pressure Booster Kit RFE-LB1 for even higher levels of performance

Also works for 68RFE, 65RFE, and 66RFE applications

This kit requires use of the input clutch retainer found in the 2007 and later units (OE number 04799648AB). All 68RFE, 66RFE, and 65RFE units should have this retainer. 45RFE and 545RFE 1999-2006 applications must replace the input clutch retainer with 2007 and later version.

Input shaft failure is common as power levels are increased in Chrysler 68RFE units. Sonnax heavy duty input shaft 72670B-01 is precision-engineered for unrivaled performance in high-horsepower gas and diesel applications. Machined from 300M ultra high-strength steel for exceptional toughness and manufactured with rolled turbine splines for resistance to spline-twist, the shaft also features a larger diameter at the cross holes for increased strength and resistance to fracture.

Suitable for any high-horsepower street, towing or competition application
Rolled splines for increased durability
Specially heat-treated and processed for maximum toughness and straightness
Manufactured from 300M ultra high-strength steel for maximum strength and resistance to fracture
Includes checkball assembly and line-bored bushing
