My '94 C3500 had been blowing gases into the radiator for about 6 months, it also has an issue with the starter that I have never seemed to be able to resolve, and the tranny had also been acting funny for a while. Well finally the transmission is stuck in second gear and won't come out. It also will barely back up. Both signs that it needs a rebuild job. I just driving my flatbed. The trouble with it is that the gas mileage is even worse than the other one and to use it for transportation is just silly. I finally got a few bucks ahead and I stopped in at our local truck dismantling place. I can get a used motor and tranny for $1100 exchange. I'm figuring that if I get a couple of years or more out of it it, isn't too bad of a deal. I can swap them out myself and I know there is always a couple of hundred in misc. expenses when you do something like this. I think I"m going to do it. I just did the brakes on it, and also just spent $1200 on a set of tires for it. It also has a nice paint job and has my sinage on it and all. It has been sitting in front of my house for 6 months.
