Bleed the clutch hydraulic system.
Attach a hose to the bleeder screw, and suspend
the hose in a container of brake fluid.
Make sure there is an adequate supply of fluid at
the clutch master cylinder, then slowly pump the
clutch pedal until no more bubbles appear at the
bleeder hose.
Refill the clutch master cylinder with fluid whenqone.
Always use Genuine Honda DOT3 Brake Fluid.
Using a non Honda brake fluid can cause corro-
sion and decrease the life of the system.
Confirm clutch operation, and check for leaking
fluid.

lf oil seal replacement is required, remove the trans-
fer assembly, replace the oil seal, and adjust the
total starting torque (see page 13-44 thru 13-61).
NOTE: Do not replace the oil seal when the transfer
assembly is installed on the transmission.

Description
Electronic Control System (cont'dl
Grade Logic Control System
How it works:
The PCM compares actual driving conditions with memorized driving conditions, based on the input from the vehicle speed
sensor, the throttle position sensor, the barometric pressure sensor ('98 model). the engine coolant temperature sensor, the
brake switch signal, and the shift lever position signal, to control shifting while the vehicle is ascending or descending a
slope, or reducing speed.

Description
Electronic Control System (cont'd)
Descending Control
When the PCM determines that the vehicle is going down a hill in E and @ positions ('97 - 98 models). and in @ posi-
tion {'99 - 00 models), the shitt-up speed from 3rd to 4th gear and from 2nd to 3rd (when the throttle is closed) becomes
faster than the set speed for flat road driving to widen the 3rd gear and 2nd gear driving areas. This, in combination with
engine braking from the deceleration lock-up, achieves smooth driving when the vehicle is descending. There are three
descending modes with different 3rd gear driving areas and 2nd gear driving areas according to the magnitude of a gradi-
ent stored in the PCM. When the vehicle is in 4th gear, and you are decelerating when you are applying the brakes on a
steep hill, the transmission will downshift to 3rd gear, When you accelerate, the transmission will then return to higher
gear.

Deceleration Control
When the vehicle goes around a corner, and needs to decelerate first and then accelerate, the PCM sets the data for deceleration
control to reduce the number of times the transmission shifts. When the vehicle is decelerating from speeds above 27 mph(4i| km,ih), the PCM shifts the transmission from 4th to 2nd earlier than normal to cope with upcoming acceleration,
