Fluid leakage check
1. Clean areasuspected ofleaking, -for example, mating
surface ofconverter housingandtransmission case.
2. Start engine, applyfootbrake, placeselector leverin"0"
position andwait afew minutes.
3. Stop engine.
4. Check forfresh leakage.

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
