i've cleaned up, de-pinned, retensioned, and repinned the N-P-R leads. I think this should solve my problem. What i think was happening is that after a cold-soak, the C lead was losing its connection due to wear/vibration. It would work, then i'd hit a bump, and it would drop the signal. i put a...

I have not found the gear range yet... but i may have solved my issue. My trans plug had an intermittent connection on the TFP C circuit.

Looking for the displayed gear. Basically, i want to catch any disagreement between the gear selected on the column and the gear that the TFP switch is indicating from oil pressure.

man, i just can't find this PID for gear range... what a pain. TJ, i admire your abilities and am jealous.

I ended up doing the same kinda thing. I just output the raw number so i can tell what its doing. Still looking for the Gear range though. gotta do my day job though first ha!

its looking like on my vehicle, the Trans range select is not in the same byte as the TFP values. Time to go hunting. yay!

I have these. Just needed the PID to be able to see what the PCM was seeing. Now i need to brush back up on binary and binary operations to isolate the A/B/C etc..

correct. when the engine is off and key on, it shows 2nd gear. This makes sense since thats all switches off. got lucky on the first one that i found it really quick and you had done the work to create the formula. Now i want to try and break the separate signals (A/B/C) out to see where...

Well, i just answered my own question and found it. Created an incremental list of the 19xx PIDs. Used the formula you guys came up with for the P/N, R, D4,D3 etc... and just scrolled through the list until i found the PID that did what i expected. Voila. If any of you have a 1999 6.5 Turbo...

Let me clarify my question as the more i read, the more specific i can be. I am assuming that each model/make etc... has its own set of PIDs that manufacturers use. Your vehicle, despite being GM, does not have all the same PIDs as my GM. I am trying to understand how you find new PIDs. Are...

Hey TJ, new here but been using Torque for a while.. I am trying to find the TFP PID for my 4L80E on a 1999 6.5 Turbo Diesel. I tried the values you had above but it does not return data. Not sure what vehicle you used this on, but how did you do the data dumps to find the correct PIDs?
