Ok, so at first all it was doing was slipping in fourth after 45mph. Then it only had second gear and I decided to start overhauling the drivetrain. I have replaced both control boxes under the dash, changed the fluid and filter, checked the shift linkages and made sure the transmission was fully engaging the gears. After I put it all back together it only had first. Then it had first and second, and then even third for a short period of time. Now it's back to just 2nd and it makes a slight grinding noise in reverse. I am looking at a master overhaul kit, shift kit, and torque converter from b&m. Anyone have any suggestions?? and how do I adjust the kick-down cable??
