Hello all. My 73 CL350 will not work in first gear, I just hear grinding and the neutral light stays on, but I can feel it "kick" into first. It just doesn't go anywhere. It also will not go up into Neutral easy. All other gears work. I can start it out in second and go all the way up to fifth with no issues in those gears. Is there a way to fix this without pulling the engine, I just got done putting this engine in. I tried playing with the clutch adjuster thinking that was the issue, but just hear the grinding. Am I going to have to throw in a new neutral and 1st gear? Thanks for any help.
