    Default 1998 Tahoe ABS light issue

    Sometimes when I leave home the ABS light will come on, speedometer will go to 0, and it will be in 1st or 2nd gear and wont do anything else until the speedometer starts back working. From what i have read on the internet, things are pointing to the speed sensor on the tranny. Have any of you had this issue with yours?
    Can anyone provide me a pic of where the speedsensor is located on the transmission.
    I have the 4wd tahoe if that matters.

    I figured i would have an answer on here.
    Anyway for future reference, the speed sensor for the speedo is at the 10 oclock position if you are under the vehicle looking to the front from the rear end. On the tail shaft there are two sensors that are identical. One is at the 10 oclock and the other is at 2 o'clock postition. There is also another one on the transfer case or box for the front drive shaft.
