Detailed Information:
This kit is complete with everything you need to build your transmission like a professional high performance builder. Starting with Raybestos Stage One frictions including a 7 friction setup for the 3-4 clutch and steel kit that includes thick kolene 3-4 steels plus turbulator low/reverse and reverse input steels. The 3-4 steels have been kolene treated. Kolene treatment is a thermochemical diffusion process, whereby ferrous parts are processed in molten salt with a specific nitrogen potential. This process provides a surface treatment that enhances wear and fatigue resistance from 200% to 500%. Also included is a complete gasket/seal kit, complete bushing kit with the teflon coated front pump bushing, the apply and backing plate necessary for proper 3-4 clutch clearance, 3-4 apply ring, three bonded input drum pistons with updated overrun spring, extra wide high energy carbon 2-4 band, a new ACDelco reverse drum (for the wide band), the "beast" sun shell, new ACDelco 5 pinion rear planetary, a 29 element forward sprag, performance separator plate, 3-4 exhaust check valve, 3rd accumulator check valve, Sonnax 3-4 replacement load release springs, thrust washer kit and OEM filter. To enhance shift performance a TruTech Transmission shift improvement kit (with "corvette" servo) is included with a FREE tub of transmission assembly lube.
In the 4L60/700r4 type transmission the 3-4 clutch is contained in the input drum. The clutch is applied when hydraulic fluid moves the 3-4 piston causing the 3-4 apply ring to engage the clutch. Over the years all these parts have been updated by General Motors. In an automatic transmission it has been proven if you increase the number of frictions in a clutch set up you can increase the torque handling capability of that particular clutch. One issue with this theory, to increase the number of frictions the steels must be thinner to get proper clearance. T he 3-4 clutch in this transmission does not work well with thin steels because of the inability to dissipate heat causing the steels to warp. General Motors went from a five friction setup in 1982 to a seven friction set up with six thick steels in the later model 4L65/70E heavy duty transmissions. However, in the standard 4L60E transmission up to 2010 model year GM used a six friction setup. All Trutech Overhaul Modules contain the seven friction, six "thick" steel clutch components. To install this clutch correctly we have included all the additional factory and/or quality aftermarket parts necessary to achieve proper clutch clearance. One additional benefit to this Overhaul Module, we have included turbulator steels for low reverse and reverse input clutches. Turbulator steels are designed with holes strategically cut into the steel. The holes prevent a temporary fluid coupling in the reverse clutches that would cause the reverse and forward clutches to be engaged at the same time. All OEM parts included in our Overhaul Module are high quality and meet or exceed factory specification.
To ensure hydraulic intregrity our Overhaul Module contains three updated steel molded input drum pistons. Because of changes to the overrun piston the overrun spring must be updated with the ACdelco spring included in the module. There are two check valves that are very important to 3-4 clutch life. These check valves are the 3-4 exhaust check valve in the input drum and the 3rd accumulator check valve. Both these valves have a direct effect on 3-4 clutch operation. We include these check valves in all our kits, we consider this low cost insurance.
In this General Motors transmission bushings play a large part in hydraulic intregrity. In a lot of rebuilds, the bushings are not replaced if they "look" good. The fact is, a small amount of wear in the bushing can cause a hydraulic leak which leads to early clutch failure. Our recommendation is replace all bushings in your Overhaul.
In the 4L60 type transmission the band is applied to move the vehicle forward in the 2nd and 4th gear range. There have been many improvements to this one component. In this High Performance Build Module we use the extra wide carbon band with heavy duty anchors. When using this extra wide band we strongly recommend replacing the reverse input drum to give the band a new wear surface. Replacing the drum is always a good idea but not always necessary when using the stock width band. Do not reuse the drum if it is discolored from heat or is warped in the band apply area.
WE HAVE INCLUDED A NEW ACdelco REVERSE DRUM IN THIS KIT.
