I haven't driven my '66 MGB much since it was rebuilt about a decade and a half ago. (I won't go into it.) At that time, it received a rebuilt transmission and overdrive from Moss Motors. I've recently started driving it, and I've noticed it is hard to shift into 3rd. It's more difficult shifting up, but it's also hard shifting down. There is no grinding or anything. It just seems to be hard to find the 'slot' and it takes a bit of force. The other gears are fine. I mentioned the overdrive for completeness. It doesn't seem to have anything to do with the shifting issue.
Since it's a 'new' transmission, does it just need to be driven to 'loosen it up'? Or might there be a mechanical problem?
