Road Testing

Perform roadtests using "Symptom" chart.Refertopage

AT-20.

"P"
POSITION

1. Place selector leverin"P" position andstart engine. Stop
engine andrepeat theprocedure inall positions, including
neutral position.
2. Stop vehicle onaslight upgrade andplace selector leverin
"P" position. Releaseparkingbraketomake surevehicle
remains locked.

"R"
POSITION

1. Manually moveselector leverfrom"P"to"R", andnote
shift quality.
2. Drive vehicle inreverse longenough todetect slippage or
other abnormalities.

"N"
POSITION

1. Manually moveselector leverfrom"R"and"0"to"N" and
note shift quality.
2. Release parkingbrakewithselector leverin"N" position.
Lightly depress accelerator pedaltomake surevehicle
does notmove. (When vehicle isnew orsoon afterclutches
have been replaced, vehiclemaymove slightly. Thisisnot
a problem.)

POSITION

1. Manually moveselector leverfrom"N"to"D" position, and
note shiftquality.
2. Using theshift schedule asareference, drivevehicle in"D"
position. Record,onsymptom chart,respective vehicle
speeds atwhich up-shifting anddown-shifting occur.These
speeds aretobe read atthree different throttlepositions
(light, halfandfull), respectively. Alsodetermine thetiming
at which shocks areencountered duringshifting andwhich
clutches areengaged.

POSITION

1. Shift to"2" position andmake surevehicle startsin1st

that transaxle downshifts to1st gear.
6. Move selector leverto"D" position andallow vehicle to
operate at30 to40 km/h (19to25 MPH). Then,shiftto"2"

POSITION

1. Place selector leverin"1" position andaccelerate vehicle.
Make suretransaxle doesnotshift from 1stto2nd gear
although vehiclespeedincreases.
2. Drive vehicle in"1" position. Releaseaccelerator pedalto
