I am now sure what the transmission was doing. I inherited the truck and don't know much about it because it doesn't run and was parked before I ever came around. It was originally my grandpas truck and my uncle told me he bought a wrecked truck and put the trans from it and in the truck I have now be cause the original transmission was make my a noise. My uncle also told Me that the different trans that was put I the truck was not right and he said it seemed to be in 2nd gear wile in third. That is why I got the original trans and I was wanting to rebuild it and put it back on the truck.And yes it was a three on the tree.
