This morning I was sitting at the stop light at Gorman and Western, and when it changed I couldn't move. I needed to manually put it in 2, and then was able to go and switch back to drive. Ideas?

solenoids are technical. ha. oops. please move.

lol

yea, if you were asking how a solenoid worked they could def answer it here

does it throw a code ever? a lot of times a bad solenoid on a GM tranny will have a manufacturer-specific trouble code

the check engine light isn't even on, so would there still be a code available?

12/9/2008 11:42:48 AM

yes.

it's possible for dtc's to exist without a cel.

we need a better explanation of the symptoms here.
