    I currently have a 2002 HD silverado with a allison transmission . During a snowstorm I noticed that the " SERVICE ENGINE SOON " light came on . I then noticed that my transmission started acting up. the LED for the gear selector was going into 3rd gear when I put it in reverse but the truck would then go into reverse. I also noticed that it would slam into drive and when put into reverse it would "jerk "
    the truck a little twice. Then when I got onto highway it would not shift into high gear . Truck has 25000 miles and is not worked hard.
    do you have any ideas?

    Mine did the same thing, it's nothing for the shop to fix if it hasn't been done already. Just a solenoid. I bet it won't stay in cc either, huh? No biggy, but I wouldn't drive it long like that.
