forman Posted December 15, 2014 Share Posted December 15, 2014 Hello Moses! I bought a truck from a relative for my son. I also purchased your book Chevrolet & GMC Light [Duty] Truck Owner's Bible that I am having sent to him, so I won't get to read it until I visit again. I should start by saying that I delivered the truck to him and will be visiting for a few more days before returning home. The truck has 171,000 miles and has been maintained fairly well aside from a slight leak in the radiator and a bad signal from the coolant temperature sensor, an oil pressure gauge that seems to read high, and a sticky brake light switch are going to be fun to repair with my son. The transmission, however, has been neglected and seems ok now but I need your advice on the best way to approach "preserving" it for a time when we can either rebuild it our selves or save up and have the work done by a professional. As I mentioned it seems ok now but occasionally seems to have a hard shift while shifting down. The trans fluid is more brown than red and I am getting ready to change it and the filter and if possible the fluid in the torque converter if you think that needs to be done. I think I was able to read the letters MD8 on the bell housing. Could this transmission be a 4L60? Also could you give us someway to test the function of the transmission so we would know how to assess any problems? Looking forward to hearing from you!
