Dogleg Shift Pattern
Some of the A-series 5-speed transmissions use a "dogleg" shift-pattern (aka 'reverse shift') and others use the standard shift pattern. The doglegs are pre-1980.
Dogleg:
R- 2 4 1 3 5 dogleg knob
Why a dogleg pattern? In racing, 1st isn't used much, but the 2-3 or 4-5 shift needs to be quick.
F5C56A is non-overdrive dogleg model FS5W63A is overdrive dogleg model FS5W60L is overdrive dogleg model
Standard pattern (aka 'straight shift')
1 3 5 2 4 R
The standard pattern is better for city traffic, where the 1-2 shift is used repeatedly.
FS5W60A is standard pattern, fitted to 2nd-year B310s
