At Trutech Performance Transmission we are proud to provide only the best parts to our customers. Our Performance Overhaul Kits are complete with all parts necessary to overhaul and upgrade the clutches and band in your transmission. We have included parts necessary to restore hydraulic integrity.Your transmission frictions will be capable of supporting up to a 550 horsepower engine. To support high horsepower engines gear train upgrades will be necessary.
This kit is complete with all Alto Red Eagle frictions including a 7 friction setup for the 3-4 clutch and a complete Kolene steel kit which includes. 106 thick 3-4 Kolene steels.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 in this kit is a complete gasket/seal kit, complete bushing set, the apply and backing plate necessary for proper 3-4 clutch clearance, thin 3-4 clutch snap ring, bonded 3-4 piston, 3-4 clutch apply ring, extra wide Alto carbon 2-4 band, 3-4 exhaust check valve, 3rd accumulator check valve, Sonnax load release replacement springs, thrust washers and OEM filter.
This kit has the proper parts to completely upgrade your early 700R4 internal parts for a stronger more reliable transmission. Included is the wider low reverse roller clutch assembly and new style low reverse piston.
This set up will give you a stronger low reverse roller clutch and allow you to install the later version low reverse turbulator steels. The forward clutch also has been updated to the 5 friction / 5 steel stack verses the 4 friction setup.The proper apply plate and wave plate are part of this kit. A later version of the input planetary ring gear is included to allow the installation of the additional 3-4 clutch frictions.
One other item upgrade is the forward sprag assembly. A newer style sprag assembly is included so the 29 element high performance forward sprag can be used. The low reverse piston, center support, input ring gear and sprag assembly are quality inspected used parts (keeps cost to a fraction of new parts).
All forward clutch parts, low reverse roller clutch and forward sprag are new parts. In the 4L60 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. One issue with this theory, to increase the number of frictions the steels must be thinner to get proper clearance. The 3-4 clutch in this transmission does not work well with thin steels because it is a shifting clutch and the thin steels have an inability to dissipate heat causing the steels to warp, especially in high performance applications. General Motors went from a five friction setup in 1982 to a seven friction set up with six. 097 thick steels in the later model 4L65/70E heavy duty transmissions.
However, in the standard 4L60/4L60E transmission up to 2010 model year GM used a six friction setup. This Trutech Performance Module contains the Alto Red Eagle 3-4 seven friction, six. 106 thick steel clutch components.These are the thickest steels available. To install this clutch correctly we have included all the additional factory parts necessary to achieve proper clutch clearance. All OEM parts included in our Overhaul Module are high quality and meet or exceed factory specification. At Trutech Performance Transmission we have found the Alto Red Eagle frictions to be an excellent high performance friction.
When using a high performance low slip friction it is necessary to calibrate the shift times to engage the shifting clutches quickly. Because this is necessary we highly recommend one of our shift modules. To ensure hydraulic integrity our Overhaul Module contains the updated steel molded 3-4 pistons.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. In this General Motors transmission bushings play a large part in hydraulic integrity. 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.Not all our modules contain bushings because the builder may already possess these, so check the listing that bushings are included if they are needed in your particular build. In the 4L60 type transmission the band is applied to move the vehicle forward in the 2nd and 4th gear range. In our High Performance Build Modules we use the Alto 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. However, the drum can be reused if it has no signs of wear. 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. Combine this kit with one of our shift improvement modules and our geartrain module to give you a strong durable transmission. This is a free service provided to our customers.
