I had about the same issue when I did v5 code. Lost vss. Jumping all over. Was not sure what happened , went back to 4145 and back to good. Got truck registered and on the road and fount out that trans slips soon as is it completely warmed up and it's a valve body issue with the 4l80e. So until I ge...

Any idea when all the documentation will catch up to the new code?

Just spent some time fixing my vss using a nte 995 sine wave to square wave converter. It was a bit of a fight due to noise but it works. It's almost the same as a lm 2907 chip.

I have had issue with vss like a lot of us on the 4l80 build. The build sheet and bom ask for 47pf capacitors in locations c28 ,c29,c32,c33. I was looking at the actual board schematics and found that there are different values. The " speedup caps" are 470pf on these prints........ I have ...

Yes it's a 12 volt signal. It would not work on gpio speed output. Hooked it straight to vss sensor temporarily so I can get the speedometer/odometer working for registration requirements. I have not put my scope on it yet. I will step resistors down / pull down etc and post findings. Thanks for the...

Gpio speedo pull-up circuit doesn't work with Abbott cable x mechanical converter. The abbott does work and is wired to vas currently. Question is what direction do I go with resistor. It's a 1k now per spec. Do I drop down to 330 or go other way. And how far can I go to no resistance before getting...

This is my first go at this... What is the best starting setup, ie what msq, ini and tuner studio settings. I have wiring setup to use pwm on all solenoids if I want. Just want a simple reliable setup starting point so I don't burn up tranny before I know what I am doing
