Little update on my transmission not shiffting issue.
I talked to my PCM programmer about this and this is what he did.
He lowered the shift points for 2-3 shifts from 70 to 65. He did it in all of the files 90-100% TPS. I reprogrammed the PCM and took it for a test drive. It is spitting rain here so this was exciting! I took off at WOT and after getting the rear end under control, first gear was very exciting, I was able to stay on it though 2nd gear. The tranny shifted at around 65 mph into 3rd, no problem. I have shift light set (just in case I want to manually shift) at 5800 and the tranny shifted right after it came on. So now the big question is why. I may call TransGo later today and see what they have to say about this information.
