Guys,
I've added two new controls and new status PIDs to the scanner for the A6 trans. These are the same procedures the Tech2 commands.
Fast Learn:
Trigger the transmission fast learn procedure. Before starting the procedure, you must log the PID "Fast Learn Status" in the scanner to be informed of various required operator actions and steps in the process. You have 2 seconds to comply with any instructions such as Selecting D or R, otherwise the test will be aborted. The engine must be running at idle, transmission temperature 70 - 95 DegC, vehicle not moving and brake pedal must be applied during the entire test. Please note during this test the engine speed will increase and decrease automatically and various clutch noises may be heard from the transmission.
Trans Cleaning Procedure:
Begin the transmission cleaning procedure. Before starting the procedure, you must log the PID "Cleaning Status" in the scanner to be informed of the current process status. Enable conditions: Engine running at idle, vehicle not moving, transmission selector in Park, transmission temperature 70 - 110 DegC. Please note during this test the engine speed will increase and decrease automatically and various clutch noises may he heard from the transmission.

Extra Info:
Fast Learn works by purging all the clutches, then asks you to select Drive calibrates pressures and then asks you to select Reverse and calibrates pressures. This is to reduce the time it takes for the transmission to purge all air from the lines and learn adaptive values, especially when new internal components have been fitted to the trans or the oil completely drained and refilled etc. There's no need to do this after every reflash, especially if you are just changing shift speeds or torque management.
Cleaning Procedure can help to remove residue from the individual clutch solenoids (pressure regulators). It does this by rapidly pulsing clutches. I have heard from service technicians that this procedure usually makes a higher mileage trans feel a little better, but can also be the final straw for a trans that is just about to fail.
