2002 2500HD problems

[GF7PE]

Ok, let me start by saying that my truck has had no problems untill the last month or so, other than an on going tranny issue that no one can diagnois. I bought the truck new in August of 2002. The truck now has a little more than 24000 miles. My warranty ran out in september and would you beleive the last month has been hell? The tranny is pretty much shot, the drivers side mirror wont defrost anymore, some of the windows barely go up, meaning they are very slow, the other day it just shut off while driving and now something is up with the abs. When its wet out and you step on the brake pedal even just lightly the pedal pulsates like abs then stops. Then the abs light come on and stays on. It will stay on if you get back in right away but if it sits for a few hours the light is off. First, what could it be? Second, Is it expensive? Third, could i do it myself?

theres a recall on the ABS, check with dealer

 

 

 

btw the tranny on my HD slips every once in a blue moon...was that what yours was doing?

I did call the dealer but they said it wasnt listed for my truck.

 

The tranny slips all the time. If I get on the highway when the truck is cold it will stay in 3rd unlocked (cruising at 65 mph rpms are around 3600) for 20 miles then will very slowly shift out. Sometimes it will start off in second gear and even if you downshift into 1st at a stop or slow roll it wont actually downshift. Once its warm, to get it into OD, you are cruising at 50 say its in 3rd gear if you hit tow haul it will downshift real quick then upshift, a few seconds later you hit tow haul again and it will shift into OD.

First: Could be a wheel speed sensor. Second: Not terribly. Third: Yep, if you know which one it is.
