Hello,

I have Cutlass Supreme 3.1 and problem with transmission.

In the morning, when it is cold, ATX won't shift anywhere and speedometer is on zero. After warming, it's all normal.

And then, after half of hour ATX won't shift to overdrive - it's like in "3".

Manual says: "when atx won't shift - transaxle system sensor is blown off"... what is it ?

Please help... (sorry on english)

I'm having a similar problem, '93 with 3.1 V6. When the car is cold in the morning, it won't go in gear until warming up for a bit. It's not otherwise slipping or anything. Once it warms up and gets in gear, it works fine for the rest of the day and then it's the same routine the next morning. Anyone have any ideas? Thanks.
