Hey all. I have a 96 Lumina with a 3.1 V6 and a 4T60E tranny. It has ~95K miles.

Over the past 2000 miles, I've noticed from time to time that as I decelerate to a stop, it stays in 2nd. As I accellerate, it stays in 2nd. If I let off of it, it blip it a little, it will go into first and be fine.

Over the past 100 miles, I've noticed that it is having a little wierd shifting around 4th, like it doesn't know which gear it should be in and switches back and forth. the 2nd problem is getting worse.

No services engine light or anything. Sensor problem?

Ideas?

Bill
