    Question about my transmission

    I have a 94 Seville STS. My car started shifting weird today. Now I have had the P056 code off and on for a long time, however the car has behaved fine no shifting issues. beginning this morning, the car was shifting funny. it seemed to be downshifting, then revving as I drove along...I stopped turned the car off and then restarted...then fine again for a few minutes then i had the problem again.

    I checked the fluid. it had a lot of bubbles, but it was the correct color..nice and red not dark..I got the car home...let it sit..started again and checked fluid...still bubbly.

    only code it throws is P056 the transmission input code and P061 cruise - vent solenoid problem. I cleared the codes the the P061 came back without driving...

    can anyone give me some suggestions on this?

    P056- Input speed sensor- 4T80E, INSIDE the trans.
    P061 shouldn't be affecting the trans.
