How to setup a 4L60E/4L65E with FTMANAGER

March 29, 2020

Step by step ECU setup for 4L60E/4L65E transmission:

The step by step instruction was built for 4L60E/4L65E transmissions wired as the diagram:

Enable Transmission Control feature:

Inputs:

TPS – Calibrated – Input must be selected according with the engine wiring.
Driveshaft RPM – Needs VR to Hall Converter (Hall wheel speed sensor can also be used).
Transmission Temperature – Default (GM USA).
Brake Switch – Default – required only if “deactivate Lockup when brake pedal pressed” feature is desired and there is no brake pressure sensor.
AT Range Selector – Switch A - Default.
AT Range Selector – Switch B - Default.
AT Range Selector – Switch C - Default.

Outputs:

Select outputs for the Transmission Solenoids (A, B and C), Blue or Gray outputs can be used.
Select according with your available outputs.
For Lockup solenoid and Line Pressure solenoid select Yellow Outputs.

Gear Change Detection:

Automatic Transmission Range Selector (lever position):

The settings for the input from the lever position should be as below:
The 4L60E/4L65E transmission sends to the ECU the same signal for Park and Neutral, so it’s the user's choice to select N or P instead.

Drive shaft RPM:

When using the 4L60E/4L65E transmission VSS, set 40 teeth and select your differential ratio and tire size info. Wheel speed sensor can be used instead.

Automatic Transmission Control:

Solenoids:

Gear change trigger table uses the same values for Upshift and Downshift:

In Other Functions – Automatic Transmission Control – Gear change trigger table.

Gear Change Table:

The values of the picture below are just a suggestion to start, do your own research and tell the ECU when to shift gears.
Do not set the same speed for upshift and downshift for the same TPS position.
The speed for upshift will always be higher than downshift, at least 2 miles/hour apart to avoid constantly gear shifting.

Gearbox Line Pressure Table:

This table is to adjust the Line pressure for smooth gear shifting and stable engine idle.
Since the line pressure directly affects the torque converter, the adjustment is needed for a smooth run and will depend on the torque converter installed.
Line pressure solenoids reduce the line pressure when activated, as so, if not using the output for controlling it, your 4L60E/4L65E will apply full line pressure at all time.
To reduce line pressure, you should increase the percentage of duty cycle on the solenoid. Values below are suggestive.

Line pressure by temperature compensation:

In Other Functions – Automatic Transmission Control – Line pressure by temperature compensation.

ATF’s density and viscosity drastically changes with temperature, that’s one of the reasons why using transmission temperature sensor is important to guarantee smooth operation. To reduce the pressure and maintain a smooth operation of your transmission system you should add more duty cycle on the solenoids, as showed:

Gear change line pressure:

in Other Functions – Automatic Transmission Control – Gear change line pressure compensation.

A momentary reduction of line pressure at the gear change, making even smoother gear changing. Suggestive values below.

Lockup Control:

Lockup Table:

The Lockup Table should follow the same logic as the gear changing table, Lock-up speeds should be higher than Unlock speeds 2mph apart to avoid constantly locking and unlocking converter.
