2000 SS A4 transmission problem?
I have a 2000 a4 SS with 119k miles on it, slp lid, headers, ory, and egr delete are only mods. Picked it up back in November and ran good ever since. Today I was cruising down the road had it in Drive and had to stop for a truck to turn. After the truck turned I took off and the transmission shifted hard from 1-2, after second it wouldn't shift into 3rd. All it would do is rev and not accelerate. The cel is on but only for a o2 sensor which I've noticed it was acting up for the past week. It shifts extremely hard and won't go into 3rd or overdrive. I changed the transmission fluid back in December, and checked the fluid when it started acting up and the level was good. What could be the problem?
Thanks,
Joe
