    Default Some issues with shifting

    Alright so I have a 2000 suburban 5.3 and recently I noticed that my transmission felt like it was delaying with shifting. Rpms went higher than normal and It didn't shift until about 90mph into 3rd gear(I'm assuming) I figured it was my superchips tune messing up so I pulled the tune off and its still doing the same thing. I'm not sure what the issue can be, never had issues with shifting. There's 118k on motor also idk if this will help but when I got the truck I hooked up a snap on scanner to it and it said shift sensor B if I remember correctly any help at all would be great...thanks guys

    If that is the code that you were given you will want to google the code and troubleshoot for that code since trannies can be rather complicated rather than a staight forward repair.

    Yeah. I have to get it back onto a snap on scanner, and re check it. Does anyone else have any input I'm really worried bout the truck due to lack of funds and winter is almost here
