Recently, my 103,000 mile 1980 SC transmission has started acting up. Shifting into 2nd is getting worse but, more significantly, I mis-shifted into 3rd and ended up with a large grinding noise. I'm finding it harder when I shift up to third to find where it is. I checked the coupler and bushings and everything is tight with little slop. The coupler has not moved and accessing reverse and all other gears are in their usual positions. Any ideas? Thinking John Walker might be rebuilding this soon before I have a catastrophic mis-shift and failure. Thanks.
