❗️New for 2024❗️

TPE "OUTLAW" Add-On shift kits for x4A33 transmissions.

This kit and service are great for your auto trans DSM or 3Si and provides ultimate performance for those purpose built drag race only vehicles!

The TPE "OUTLAW" Add-On kit comes with all the hardware to transform your TPE "Street" or Translab kit equipped valve body into a precise shifting drag car!

This kit raises effective line pressure to as high as 270psi*, physically eliminates 4th gear operation, minimizes 1-2 shift binding, removes potential bleed paths through the inactive PCSV and DCC solenoids, pins shuttle valves to prevent bleed paths that dont need to move in a full pressure shifting drag trans, and improves oil inlet flow to the pump. The kit needs to be paired** with the RD port mod, a front clutch upgrade, anf likely a welded center diff, rear drum, and transfer gear upgrade. This is the premier shifting option for your transmission!

The instructions for this kit provide great detail to aid in not only the installation of hardware but the additional modifications to make and issues within the Valve Body to look out for.

DIY kit is only $240 or can purchased with TPE installation service for only $350!!

If you have a stock valve body, the "OUTLAW" full shift kit is also available which incorporates all the benefits of the TPE "Street" kit along with the "OUTLAW" add-on kit benefits! DIY full kit is only $345 or with the TPE installation service for only $600!

* - Effective line pressure subject to particular transmission build and operating conditions.

**All high pressure valve body builds should have pressures monitored and adjusted based on the particular transmission build and converter pairing.

Who else is busy with the !?

The Talon is ready for some laptop work now and see what we can do with this new Turbo Parts Canada Inc. GTR Spec Turbo!

We will be running the 9.50 class but expect some PBs in Norwalk in a couple weeks as we shake the car down and stretch its legs to find that 9.500 tune up!

Also, we plan on bringing some shift kits with us so if you want to pre-pay and pick up at The Shooutout, that would save you on shipping! If you are feeling froggy, we could do the install trackside too!!

RACE ON!!
