Anyway to fool 411 PCM into thinking its connected to 4L60E for TCC operation?

You can try playing with the P1810 processing enabler, see if that makes any difference...

The manual says the PCM will command a D4 shift pattern, but it doesn't say if it will apply the TCC.

If you can somehow rig up N,R,P signals from the manual lever position, then it would work properly:

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.

Ok, I see.

Have you tried this:

Try grounding just pins R (C2-17) and P (C2-18)... and leave pin N (C2-63) un-grounded.

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.

[slow89irocz]

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?
