I think I have an idea of what it may be based on this post:
zerothread?id=247136
The post is in reference to an FWD transmission, but it may be applicable to RWD.
I will have to look into the suggested potential trouble areas:
- Clutch assembly- Clutch adjustment (?)- Clutch hydraulic fluid- Shifter assembly (I have a B&M SS unit)- Transmission fluid- Synchros
I hope that it may just be as simple as the clutch adjustment and the hydraulic fluid.
