I had cruise set. Went up a slight hill and it down shifted. Once the road leveled out, it would not return to the proper gear. I tapped the brakes to cut the cruise off and coasted a few seconds. It still wouldn't shift back. I turned about a mile later and when you give it gas, it wouldn't shift. I stopped completely, and sat a few seconds. When I start moving, it feels like it's starting in 2nd or 3rd gear. It will shift like once. I checked tranny fluid, and it's low, but there is some on the dipstick. It does not drip any on my driveway.
Any chance adding some back will help this? It's always shifted flawlessly.
Also, what type transmission fluid do I need?
