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.

NOTE: Keep all foreign particles out of the transmis-
sron.
1.Warm up the engine to normal operating tempera-
ture (the radiator fan comes on)
Park the vehicle on the level ground, then turn off
the engrne.
Remove the dipstick (yellow loop) from the trans-
mission. and wipe it with a clean cloth.
Insert the dipstick into the transmrssron
Remove the dipstick and check the fluid level lt
should be between the upper mark and lower
marks.
UPPER MABKLOWER MARK
lf the level is below the lower mark, pour the recom-
mended fluid into the tiller hole to bring it to the
upper mark. Always use Genuine Honda Premium
Formula Automatic Transmission Fluid (ATF). Using
a non-Honda ATF can affect shift quality

Line Pressure/1st Clutch Pressurc Measurement
1. Set the parking brake, and btock both rear wheels securely.
2. Start the engine, and run it at 2,OOO rpm.
3. Shift to N or E position, then measure line pressure.
NoTE: Higher pressure may be indicated if measurements are made in shift lever positions other than @ or @ positron.
4. Shift to tq;l position, hold the engine at 2,000 rpm, and measure 1st crutch pressure.
