TransGo 4L60E-3 Reprogramming Kit 4L60E and 4L65E Transmissions Holden Commodore VR VS VT VU VX VY VZ VE

TransGo 4L60E-3 Full Manual Reprogramming Kit – Holden Commodore VR VS VT VX VY VZ VE – 4L60E / 4L65E / 4L70E / 4L75E

The TransGo 4L60E-3 Reprogramming Kit converts compatible GM 4L60E-family automatic transmissions to full manual shift control, allowing the driver to manually command 1st through 4th gear without relying on factory TCM shift functions.

Suitable for applicable Holden Commodore VR, VS, VT, VX, VY, VZ and VE models fitted with 4L60E, 4L65E, 4L70E or 4L75E transmissions, this kit is designed primarily for performance, competition, off-road, conversion and transplant applications where full manual gear control is required.

4 SPEED AUTO ONLY – WILL NOT SUIT 5 SPEED TRANSMISSIONS IN VZ SV6, VZ CALAIS OR SPECIFIC VE MODELS.

Once installed, the transmission will only shift when manually commanded. The kit can also be converted back for use with a factory or aftermarket transmission controller if required.

Benefits:

• Full manual control of 1st through 4th gear

• Manual upshifts and downshifts

• Short, firm performance shifts

• Improved transmission durability

• Improved line pressure control without a factory TCM

• Greater driver control in performance applications

• Suitable for conversion and transplant vehicles

• Helps reduce burnt 2-4 bands

• Helps reduce burnt 3-4 clutch plates

• Helps reduce burnt forward clutch plates

• Helps reduce burnt low/reverse clutch plates

• Helps reduce pump and valve bore wear

• Helps control erratic pump slide movement

• Includes high-RPM protection for the 3-4 clutch

• Can be converted back for use with a factory or aftermarket TCM

The included vacuum-controlled line pressure system and .500" boost valve allow the transmission to generate an aggressive and controlled line pressure curve without relying on electronic TCM pressure control.

The included TransGo 7-CS clutch spring kit is designed to reduce centrifugal 3-4 clutch apply at high engine speeds, helping protect the 3-4 clutch in applications operating at approximately 5500 RPM or higher.

• GM 4L70E

• GM 4L75E

Generally suitable for 1993-2011 applications, excluding Hybrid transmission variants.

Holden Applications:

Suitable for applicable:

• Holden Commodore VR

• Holden Commodore VS

• Holden Commodore VT

• Holden Commodore VX

• Holden Commodore VY

• Holden Commodore VZ

• Holden Commodore VE

Important: 4-speed automatic applications only. This kit will not suit 5-speed automatic transmissions fitted to VZ SV6, VZ Calais or VE models.

Always confirm the transmission model before ordering.

Important Installation Notes:

On 1993-2006 transmissions without an input speed sensor, the main kit can generally be installed with the transmission still in the vehicle.

Later transmissions fitted with an input speed sensor require transmission removal to install the .500" boost valve components correctly.

The included 7-CS high-RPM clutch spring kit also requires transmission removal if being installed.

Torque Converter Clutch Note:

This kit does not provide automatic torque converter clutch control.

If retaining a lock-up torque converter, the TCC will require separate electrical control.

Recommended Application: Performance, competition, off-road, conversions and vehicles operating without factory transmission control

Installation Recommendation: Experienced transmission technician
