No Compromise Overdrives !


4L80E Components

4L80E Transbrakes!!!
We're excited to offer our new 4L80E transbrakes. Our testing has convinced us that it is the fastest releasing transbrake on the market for the 4L80E.
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 transbrake does not require a deep pan like our competitors.

Priced at $500 for a valve body assembly.

We now offer two versions of the transbrake.

Our Street 4L80E transbrake is designed for less aggressive combinations. It offers the ability to downshift to low while moving, slightly less aggressive 1-2 shifts, yet still has the fast releasing design that our transbrake is known for.

Our Pro 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.

Both are priced the same and work on the same principle, we are offering both versions to fit more customers needs.

Look for more options in the future as we release more of the best 4L80E parts on the planet developed at Jake's Secret Squirrel R&D lab.

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 $150.
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. $110 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
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.
$30 shipped.
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.
