Features and benefits:

The TransGo Reprogramming Kit comes with everything you need to recalibrate the accumulators, feed orifices as well as pressure regulation for street, strip, and off road. The resulting increases clutch plate durability and produces short-firm shifts that are perfect for hot rods as well as work trucks. In addition, when using the included optional low hold 1-2 shift valve, the transmission will stay in low gear with lever in manual low position.

The kit also includes a drop-in USA-made hardened steel TCC relay boost valve and bushing that restores the hydraulic circuit integrity for all type two, three and four valve bodies except some Lexus models. This hardened steel boost valve and bushing assembly provides you with a durable direct replacement for the soft aluminum OEM assembly that is prone to wear. The kit can also be installed with the transmission in vehicle.

Corrects, Prevents, Reduces:

  • Soft shifts
  • Burnt clutch plates in hot rod and work truck application.
  • TCC slip and overheating on type two, three and four valve bodies due to wear at the lock-up relay valve.

Great Upgrade
Got this kit for my daughters Jeep and it works fantastic. The Jeep has a small lift and bigger tires and this firmed up the shifts and drives way better. No more soft or lazy shifting! OPT guys are great to work with.
