Ok so update for everyone.
No it was not the PNP sensor. Put the new one in and got it adjusted to read proper at each selection.
CEL comes on after about 5 seconds. P0705.

Car starts and drives, seems to go through all the gears but it unsure what to do when you floor it. I can feather it right up to 150km but cannot floor it to get there as the trani will shift in and out of gear or bog down to a stall.

I swapped out the shift solenoids, PNP and TCM as part of my diagnostics.

I am still thinking it is an electronic fault. The arrow light may be a clue.
It does not come on when 3 or L is selected. it works when W is selected.

Does anyone know what triggers the tcm to turn the light on?
Am i missing something?
Thanks all
