I noticed recently that my tranny is slipping when in drive. When I put it in drive and hit the gas the truck acts like the parking brake is on. It move a little but it takes a lot of gas. One time it almost felt like it "dropped in" and then went fine. Lately I have been starting out in "1" and shifting manually to get around this.

I checked the fluid and it is to the top of the range but I noticed it has a brownish tone to it. It is an '01 with about 80,000 miles on it.

Is this a typical scenario with these trucks? If so, what is the fix? I know a local guy that is real good at working on these trucks and I was going to give it to him but figured I would check here first to see what you all think.

 

When was the last time you had it serviced?? Only thing I can say is drop the pan and see how much material is in it.

 

Sounds like the Governor Pressure solenoid and transducer is your problem. If you shift through the gears manually just fine, that is what it is. Put a filter in it while your at it. You have to drop the pan to change the parts out.

 

Thanks for the response. I just noticed I put this in the wrong place....should have been in 2nd gen.

 

My 2nd gen gasser was acting up. Changed the fluid and it took care of the shifting issues.
