Aisin A442 and A450 control possible?

Postby Roloside » Tue May 16, 2017 4:41 pm

These transmissions use the same solenoid pattern as the Aisin A340 series, but they have 4 solenoids instead of 3. The 4th solenoid is the timing solenoid. So far what I can find on the timing solenoid is: "The timing solenoid is used for the
1–2 upshift, the 2–3 upshift, and the 3–2 downshift. Its purpose is to control the orifice of the 2nd brake, which reduces shift shock."

What information about the timing solenoid is required to control these transmissions?

Thanks!

Can anyone offer a suggestion for making this work?
