We're excited to offer our new 4L80E transbrakes.
It works with normal automatic computer controlled functions. It can be installed with the OEM GM electronics, aftermarket standalone controllers, or operated as a full manual shift setup without external controls using our full manual kit.
Our 4L80E transbrakes do not require a deep pan like our competitors.
We now offer two versions of the transbrake.
Our Pro "D3" 4L80E transbrake is designed to allow transbrake launch from any forward gear. It was designed with the automatic shift by PCM or controller in mind. Ideally it will be launched from the D3 shifter position and shifted by the controller. Activating the transbrake button is required for reverse function. It has a revolutionary design for 3rd gear feed.
Priced at $600 for a valve body assembly.
Our "Manual Low" or D1 4L80E transbrake is the version that we are known for. Hard hitting, no compromise, take no prisoners design for the serious competitor who really only needs it to get down the track and is manually shifting. It will work with auto shift but must be in the D1 or manual low position to engage the transbrake. This has been one of our most popular products ever and due to it's popularity we are now offering it at an even lower price of $400 as a VB assembly.
4L80E Full Manual Control
We offer a plug and play full manual control option for the 4L80E. Simple two wire hookup, 3 wires if you are using our transbrake. Cost is $200 plus $10 shipping in the cont. U.S. This is included for no charge with our full manual transmission builds.
4L80E Valve Body Calibration Kit
During our extensive research and testing of the 4L80E we've developed a valve body calibration that gives positive shifts without damaging parts and also eliminates some common problems.
Our Valve body calibration kit includes a new seperator plate, boost valve, and other parts to make your 4L80E shift firmly. $150 shipped.
4L80E Adjustable Pressure Regulator Assembly
We have developed our exclusive adjustable pressure regulator assembly for use in combos with elevated power levels where fixed line pressure is desired, precise adjustment of line pressure is important, and absolutely stable pressures are critical. This assembly eliminates all hydraulic inputs on the pressure regulator spring. Line pressure is very stable with ease of adjustment. New pressure regulator spring included.
$90 each shipped
4L80E Shafts and Drums
We stock our own line of billet and hardened internal components.
300M Input Shaft $400
Intermediate Shaft $350
Forward hub- $150
We also have the 4L80E Super Drum assembly. It uses a sprag with 36 elements that are 30% wider than the traditional 34 element upgrade. We recommend this drum for 1000+ HP/TQ combos, higher rpm combos, and in some off road applications where sprag failure is an issue. We are making these in house now to save our customers money. The inner race is made of 8620 bearing grade material heat treated and pressed onto the drum. Frictions, steels, and pressure plate included $600.
4L80E Pressure Control Solenoid Eliminator Plug
Our PCS/EPC eliminator plug allows a simple easy method to achieve fixed line pressure. It "loops" the actuator feed circuit to the torque signal circuit allowing the boost valve in the pump to stay in the "boosted" position. This works great in full manual builds and when the power level is high enough to need fixed lne pressure.
4L80E Optishift Standalone Controller
We are a dealer for the Baumann Electronics "Optishift" controller. We feel this is the best controller on the market. User friendly, excellent tech support, latest technology, and excellent pricing.
We match the MSRP of $590 and offer a discount with transmission purchase.
