Stall Speed
Test
CAUTION:
. To prev€nt transmission damage, do not t6st stall speed for more than ro sgconds at a time.. Do not shift the levor while raising the engine speed.. Bo sule lo remove the pressure gauge betoro testing stall speed.
'1. Engage the parking brake, and block the front wheels.
2. Connect a tachometer to the engine, and start the engine.
3. Make sure the Ay'C switch is OFF.
4. After the engine has warmed up to normal operating temperature (the radiator fan comes on). shift into E position.
5. Fully depress the brake pedal and accelerator for 6 to g seconds, and note engine speed.
6. Allow two minutes for cooling, then repeat the test in @ and @ positions.
NOTE:
. Stall speed tests should be used for diagnostic purposes only,. Stall speed should be the same in o., E and E positions.
Stall Spsed RPM:
Specification: 2.700 rpm
Service Limit: 2,550 - 2,850 rDm
TROUBLEPROBABLE CAUSE
. Low fluid level or ATF pump outDur. Clogged ATF strainer. Pressure regulator valve sluck closeo. Slipping clutch
. Slippage of 4th ctutch
. Slippage of 2nd clutch
. Slippage of lst clut"tr or. t"t g""io*-*"y "lut"h

24. Installthe intake air duct.
D16Y7 engine:
Install the intake air duct and the resonaror.
D16Y8 engine:
lnstall the intake air duct and the air cleaner hous_ang assembly.
25. Refill the transmission with ATF (see page 14_1.18).
26. Connect the positive (+) cable first. then the nega-tive (-) cable to the battery.
27. Check the ignition timing (see section 23).
28. Start the engine. Set the parking brake, and shift thetransmission through all gears. three times. Checkthe shift cable adjustment (see page 14_190).
29, Check the front wheel alignment (see section 1g).
30. Let the engine reach operating temperature (thecooling fan comes on) with the transmission in Nor @ position, then turn it off and check the fluidlevel (see page 14- 7).
31. Road test as described on pages 14-113 thru ,14_116.

Stall Speed
Test
CAUTION:
. To prevent transmission damage, do not test stall sp€€d for mole than 10 seconds at a time.
. Do not shift the lsver whils raising the engine speod.
. Be sure lo remove the pressure gauge before tosting stall speed.
. Stall speed tssts should be used tor diagnostic purposes only,
1. Engage the parking brake, and block the tront wheels.
2. Connect a tachometer to the engine, and stan the engine.
3. Make sure the A/C switch is OFF.
4. After the engine has warmed up to normal operating temperature (the radiator fan comes on), shift into E position.
5. Fully depress the brake pedal and accelerator for 6 to 8 seconds, and note engine speed,
6. Allow two minutes for cooling, then repeat the test in E, E, and E positions.
Stall Speed BPM in E poshion:
Specification: 2,500 rpm
Servic€ Limit: 2,350 - 2.650 rpm
Stall Speed RPM in E, E and E positions:
Specitication: 3,000 rpm
Service Limit: 2,800 - 3,100 rpm
TROUBLEPROBABLE CAUSE
Stall rpm high in @. p. [, and @ positionsLow fluid level or ATF pump output
Clogged ATF strain€r
PH regulator valve stuck closed
Slippage of forward clutch
Faulty start clutch
Stall rpm high in E position. Slippage of reverse brake. Faulty start clutch

Power Distribution Schematics
Power Distribution schematics show how power is supplied from the positive battery terminal to
various circuits in the car. Refer to the Power Distribution section to get a more detailed picture
of how power is supplied to the circuit you're working on.
From Battery to lgnition Switch, Fuses, and Relays
Individual circuit schematics begin with a fuse. The first half of Power Distribution, however,
shows the wiring "upstream" between the battery and the fuses.
