2. Engine idle speed.
3. Manual lever adjustment.
ROAD TEST
The road speed figures for the tests listed below are to be found under "GENERAL DATA-GEAR CHANGE SPEEDS".
Road testing should follow the complete sequence detailed below. Transmission should be at normal working temperature, i.e. after being driven on road or rollers.
1. With brakes applied and engine idling, move selector from.
"N" to "R"
"N" to "D"
"N" to "2"
"N" to "1"
Engagement should be felt with each selection.
2. Check stall speed.
3. Select "D", accelerate with minimum throttle opening and check speed of first gear to second gear shift.
4. Continue with minimum throttle and check speed of second gear to third gear shift.
5. Select "D", accelerate with maximum throttle opening (kick-down) and check speed of first gear to second gear shift.
6. Continue with maximum throttle and check speed of second gear to third gear shift.
7. Check for kick-down shift third gear to second gear.
8. Check for kick-down shift second gear to first gear.
9. Check for kick-down shift third gear to first gear.
10. Check for "roll-out" down-shift with minimum throttle, second gear to first gear.
11. Check for part throttle down-shift, third gear to second gear.
Should a fault be apparent during road test, first identify the problem from the list printed in the Fault Diagnosis Chart. The reference numbers shown opposite each fault may be translated by reference to the list headed
