Please add to these Transmission Diagnoses and Corrections based on your experience.

Difficulty Switching Gears
- First gear won't go in if car rolling
- By design: 1st gear is not sychro
- Noise, trouble shifting into one specific gear
- Bad synchro
- Bad gear, perhaps chipped
Slips Out of Gear
Although rarely occuring this is one of the weak points of the 56- and 60- transmission designs.
- Shifter mechanism
- chipped gear
Noisy
Component Determination
Try to determine if it is a transmission or some other component:
- Clutch pedal down, noise goes away. Clutch pedal up, noise starts
- Transmission input shaft or counter gear
- Noise only when clutch pedal depressed
- Throwout Bearing is bad
- Noise at any gear, at certain road speed
- Vibration in any gear, at certain higher speed
- Noise in a particular gear over a range of speed. No noise in lower or higher gear
- Transmission
Potential Causes
- Low on gearbox oil
- Leak
- Not filled with enough oil
- Filled too full
- Worn bearings (whine at high speed)
- Bad bearings or bushing (knock at low speed)
- Clunk - worn splines
