I just bought a 04 Silverado 1500 and the tranny was blew up in it. I went and had it rebuilt to a stage 1 performance tranny and I got a stock torque converter for it. It has the 4.8 in it but when I bought it the guy told me it was the 5.3, so I bought a converter for the 5.3 but then realized it was a 4.8. So I took it back and got the right one but when I put it in the tranny and get it up and ready to mount it won’t go in cause it’s to big. So I go back and get the one for the 5.3 which is smaller and it fits in and I’m able to get it up on the motor and get the brace back under it and all that good stuff, I thought I was home bound lol but then I go to move the fly wheel to tighten the converter bolts more and it won’t move at all so I loosen everything up and I’m then able to move it so I tighten the bolts on the converter and then tighten everything else back up but I figured something was wrong with it not moving at all so I throw the starter back on the see if it makes any weird noises and if it’ll work when I crank it and the starter starts making his loud grinding noise and smells like it’s burning when I crank the truck up. I don’t know if I need to adjust the starter or if it’s cause the torque converter sapossibly isn’t the right one or what but I sure could use some help.
