If the line was cut or off, the modulator would be commanding more line pressure. The more the vacuum the less the line pressure.

Well I'm fairly confident that at least its not going to strand me so I can cruise around and try and diagnose. Putting together a scanner config to log tranny data see if it tells me anything.

Didn't know you could log tranny input rpm and output rpm, compare this with engine rpm and I'll be able to tell at least where the slip and how much is happening.

I've retuned. PWM Maximum 100% across the board, PWM Minimum 90% accross the board and lock the converter part throttle 3rd and 4th at 80mph. Can't make it slip now and 4th looks better than all the other gears. I am concerned about the TC more than trans now. Don't understand it but gonna drive it and see what happens.

On another note my VIG is now a 2900 stall. Thinking about getting it re-stalled back down.
