4T65E-HD Transmission

Description

INCLUDED:
-Fully remanufactured valve body, with updated TCC Control Valve, TCC Regulator Apply Valve, Torque Signal Regulator Valve, and Reverse Boost Valve, improves shifting, lubrication, and performance.
-Completely remanufactured pump, including replacement of slide pivot pin, provides consistent internal pressures, eliminates pump slide malfunction, and eliminates slipping and/or delayed engagement.
-Pump driveshaft seal updated to solid Teflon seal for prevention of torque converter lockup, slip, and chatter.
-Thoroughly inspected Input clutch housing thrust bearing assures proper endplay and eliminates noisy operation.
-Updated 4th clutch shaft prevents loss of 4th gear due to stripped splines.
-New EPC solenoid assures proper line pressure control and shift feel.
-Updated Actuator Feed Limit Valve assures proper solenoid pressure feed.
-Clutch clearances set to custom-spec standards for improved shift feel and timing.
-Fully remanufactured torque converter is tested for leaks, lock-up, concentricity, and balance. Upgrades exceed OE requirements and eliminate the possibilities of front seal leaks, premature bushing wear, and vibration.
-Thoroughly inspected torque converter support bearing to prevent sleeve failure.
-Bushings and machined surfaces polished to a mirror-like OE finish of 15 RA or less.
-Tru-Flat qualification process applied to transmission case, valve body, pump, and channel plate prevent cross leaks and pressure losses
-All-new custom-spec bushings to improve internal fluid flow control and pressures.
-Complete system correction and recalibration kit installed to address several OE flaws, reduce slippage and increase durability. Modifications include updates to servos, the PR system, and valve body accumulators.
-Complete road simulation using a dynamometer testing program called C.A.R.S. (Computer Aided Road Simulation). Every transmission is cold and hot tested before shipment.
