Finally, we include a low stall heavy duty carbon composite lockup clutch torque converter.Īs with all our units shipping is free within the mainland USA and there is no core charge on all 60 & 65 units. We enlarge the apply release feeds for the lockup clutch to make it apply positively and avoid converter clutch burn-up under heavy load. We improve the flow to the 3-4 clutch set, making sure it has enough supply to hold the load on this crucial shift. This greatly extends the converter life and helps to keep everything much cooler. Here we perform all the updates for lube and durability, and eliminate the partial lockup function in the 4L60E. The Heavy Hauler Series uses 4 pinion planetaries. A lack of lube and cooling is a killer when pulling the boat, camper, or work trailer loaded down with equipment. This is a must in these heavy duty units. Moving on, in the planetary, both sun gears are modified to increase lube flow. You will not have to worry about that sudden loss of reverse, 2nd, and 4th gears associated with the breakage of this piece. They are almost twice as thick as a hardened or new OEM shell and they have a reinforced collar. To address this, we use only the GFX Shell.
In particularly heavy vehicles, vehicles used for heavy loads, and those used for off-roading, constant shifting occurs from first to second and reverse. We next attack a weak link, the sun shell. Some additional modifications to the 3-4 set and this clutch pack prevent scoring and burning and increase hold. More friction plates than stock which is 6 in most cars and trucks. This is important because the clutch has to bear the load in every gear except reverse.įor the 3-4 clutch, we use 8 heavy duty friction and steel plates. They have superior temperature capabilities and they don’t burn easily, even in the worst conditions. These clutches have an outstanding friction coefficient for maximum holding. We use carbon composite friction plates in the forward clutch set. Now you have nearly double the load capabilities of the stock transmission in overdrive. That, accompanied with the 20 percent wider band, will let you tow in overdrive with confidence. This servo has more holding force than the stock overdrive servo. It will supply the clamping force needed for these heavy units without the excessively harsh shifts associated with the aftermarket “super servos.”įor Fourth (OD), we use the Proprietary Performance Billet servo. This servo is the largest servo available from GM. To compliment this, we use the Corvette servo. We use a heavy duty wide band for maximum hold in second and fourth gear. These units feature a heavy duty, 13 vane pump with staked bushings, full-time lube modification to keep the heat down, and a modified lockup valve to improve the lockup converter’s durability so you can tow confidently in overdrive. The shifts on these units are designed to take the abuse and work associated with these vehicles, but without the tire chirping shifts of our race and performance units. These were specifically developed for commercial, heavy towing, and 4×4 vehicles. These units are built very similarly to our Pro Race units, but the focus is on durability while maintaining reasonable shift quality. You are looking at the PerformaBuilt Heavy Hauler Series transmission. A Core is Required to Build this Transmission
