You could do something simpler:
let the 4th gear pressure switch apply the TCC... i.e. the standard 700R4 circuit of 4th gear switch (NO) in series with brake switch (NC);
you could then run with a manual trans segment in your PCM.
I tried to use the 4th gear switch but it locks too soon really lugs the engine. 3200rpm stall converter. Thats why I want to get the PCM involved so I can control the mph it locks at.
Yep when I took it for a test drive last night I had pins R and P grounded and a 660ohm resistor for the temp sensor. All the TSTATE09 bits were no. However it was strange that the GEAR PID went from being 3 in park to 1 when I started moving. Once again no lockup......
The PCM might not be happy that there are no shift solenoids.
I am going to make a connector that will allow me to put a resistor in place to simulate the solenoids. From pins E to T, E to S, and E to A I will use a 22ohm resistor. From Pins E to U and E to B I will use a 10ohm. from pins L to M I will use a 680ohm. From pins D to C I will use a 5ohm resistor. I will ground pins R and P. Do these resistor values look correct?
