Now a blinking power light

[wyhlenout]

Fix 1 or 2 problems and another starts... Washed my car and got my summer tires put on. As soon as I get my car back I notice my cars trans is shifting all weird as in shifting later and a lot more stiffer.

Restart the car, notice the power light is blinking. So looked around on here see there is a procedure to pull the code. No luck on getting the code. Seen that a common fix is to change the resistor. So popped on my "resistor mod" resistor that I had laying around. That didn't fix it.. When I drove up a hill gave it more gas to put it in power mode. It went in. But it didn't come out until I stopped and shifted back to park..

This is a 4.44 trans in the car. I don't think that makes any difference however..

Any ideas?

Thanks guys
