Introduction


AFFILIATE MARKETING

What is the first rule when working with any mechatronic units?

Be ESD Protected.

Bus testing in the vehicle with E-Zee Shift

Before removing the transmission for repair, it is important to verify that vehicle sensors are transmitting correctly on the CANBUS.


AFFILIATE MARKETING

An intermittent signal from any powertrain sensor can cause faulty transmission symptoms!

In this video, we are monitoring sensor information on the vehicles CANBUS with E-Zee Shift. We found that the TPS sensor was transmitting an irregular signal. It was later found that the vehicles spark plugs were emitting noise andy causing interference to the TPS BUS messages and thus causing erratic shift problems, The transmission had no fault.

CANBUS-VS K-LINE / X-LINE DIAG SHIFT INDUCTION


AFFILIATE MARKETING

• Transmissions rely on CAN BUS Messages when in the Vehicle.

• We can easily record or emulate the CAN sensor messages from the vehicle and send back to the transmission on the dyno,

• Example of emergency mode can message 0x123. Appears when TCM ‘Does Not’ Have the required CANBUS sensor information.

• Vehicle specific, not transmission specific. WHAT VEHICLE IS THIS TRANSMISSION GOING BACK IN TO? FLASH FIRST, TEST AND CHECK YOUR RESULTS !!!

NOT AS SIMPLE AS CONTROLLING A SOLENOID WITH CURRENT!

CALIBRATING WITH MECHATRONIC SOLENOIDS

After rebuilding and re-flashing, calibration is also required.


AFFILIATE MARKETING

Tuning the Mechatronic control to theSolenoids is required.

Replacement Solenoids can be fittedBut ‘Basic setting’ must be performedOr there will be ‘Driveability’ problems.

The flash reprogramming proceduresmust conform to SAE J-2534

Mechatronic and E-Module


AFFILIATE MARKETING

Electronic Control Module

The Mechatronic is constructed from Substrate Base on Ceramic.

Temperatures above 150 deg C will have a detrimental effect on performance.

At 155 deg C component damage will occur.

3 Stage function of temperature control.

Stage 1: At 126 deg C, Shift points are higher and Lock-up

range is extended.

Stage 2: At 141 deg C, Engine torque is reduced by up to 40%

Stage 3: At 147 deg C, Solenoid power is de-activated

Conclusion

Modern Day Transmissions and Valve Bodies are in fact much easier to Work with. As long as You Know The Basics!!!

Know your limitations.

Educated engineers.
