FAULTTRACING ROADTESTING (Usedtoçther with the fault-tracingscheme.) It is important to g€in as much information as possible ss to the precise nature of any fault. lf possible,go out in the car with the customerandget him to demonstratethe fault. In all caæs, the following road-testprocedureshould be carriedout completelyasthere may be mgre than one fault. TESTNO. 1. Checkthat the starter only operate3with the selectorin "P" and "N" and that the reversing lightoperatesonly in "R". 2. Apply the brakesand,waththe enginerunningat normal idling s.peed,ælect "N-D", "N-2", "N-1" and "N-R". Transmission engEpment shouldbe felt in eachpositionselected. 3. Checkthe converterstall speedwith the trans, missionin "1" and "R". Gheckfor slip or clutch squawk. Note.Do not stall for lonçr than 10 seconds or thetransmission will overheat, 4- With the transmissionat normal runningtemperaturo,select"D". Release the brak$ and accelerate wjth minimum throttle opening.Checkfor 1-2 and 2-3.shifts. Note. At minimumthrottle openings,the shifts may be difficult rc deteet.

7a. Stop and restart using forced-throttle acceleration. Checkfor 1-2'and 2-3 shiftsaccordingto the shift speedtable in the "Specifications". b. At 65 kmph (40 mph) in 3rd gear,releasethe accelerator and select "1". Check tor 3-2 downshiftand enginebraking.Checktor rollout 2-1 downshift at about 8 kmph (5 mph) and enginebraking. 8. Stop, and with "1" still engaged, releasebrakes and, using full throttle, accelerate to 30 kmph (20 mphl. Checkfor no slip or clutch squawk and no upshifts. 9. Stop and select "R". Releasebrakes and reverse using full throttle if possible.Check for no slip or clutch squawk. 1 0 . Stop on the brakes facing downshift on a gradient and select "P". Releasethe brakes and check that the parking pawl will hold the car. Re-apply the brakes before disengagingthe parking pawl. Repeat with the car facirg uphill. Check that ttre selector is trapped by the inhibitor in "P".
