TH700/4L60E Stage 3 (Full Manual)

We love the TH700 / 4L60E transmission!

Our stage 3 modifications include the fitting of a corvette servo (hi-apply area), the full manual valve body kit, forward, 1-2 and 3-4 gear shift accumulator pistons.

Please be aware, The Stage 3 modifications (Full Manual) make the transmission shift into what ever gear the t-bar (gear selector) is in, there are no safety features to ‘stop things blowing up’!!!

The full manual valve body kit provides modifications to the following components:

  • pressure control valve
  • accumulator valve
  • lock-up valve
  • hydraulic circuit orifices
  • gear shift accumulator springs
  • shift valves to provide the FULL MANUAL functions

*** It provides an awesome feeling shift (you’ll notice a huge difference) by increasing the apply pressures;
*** It extends the transmission life by increasing lube oil;
*** It repairs common wear areas in the valve body hence saving hard part costs.
*** As well as being FULL MANUAL.

When fitting the kit we also fit a new filter, carry out a transmission service and install band adjusting shims where required.

For a 4L60E this kit allows the transmission to be installed without the computer being hooked up or into a completely different vehicle without any electronic controls.

Our Hi-Performance overhauls include the following:

  • Full manual shift kit, parts and modifications to the valve body as explained above
  • Reconditioned torque converter and new lock-up plate (stall speed can be modified to up to 3000rpm at no extra charge)
  • Overhaul Kit
  • Filter
  • Full set of friction plates
  • Thrust Washer Kit
  • Bush Kit
  • Accumulator Piston Kit
  • Raybestos 3-4 Cluck Z Pack (single-sided clutch system that outperforms OE in torque and heat capacity)
  • Heavy duty band
  • Extra friction plates installed in the forward and high (3rd gear) clutch packs
  • New Pressure Control Solenoid (4L60E Only)
  • 2 New Shift Solenoids (4L60E Only)
