Description
General Operation
The Automatic transmission is a 3-element torque converter and triple-shaft electronically controlled unit which provides 4
speeds forward and 1 reverse speed The unit is positioned in line with the engine'
There are two tvoes of automatic transmission on CR-V; the four-wheel drive (4WD) model ('97 - 00)' and the front-wheel
drive (2WD) model ('98 - 00).
Toroue Converter, G€ars, and Clutches
The torque converter consists of a pump. turbine. and stator assembly in a single unit. The torque converter is connected to
the engine crankshatt. These parts turn together as a unit as the engine turns. Around the outside of the torque converter is
a ring gear which meshes with the starter pinion when the engine is started. The torque converter assembly serves as a fly-
wheel while transmitting power to the transmission mainshaft.
The transmission has three parallel shafts: the mainshaft. the countershaft, and the sub-shaft. The mainshaft is in line with
the engine crankshaft. The mainshaft includes the 1st, 2nd. and 4th clutches, and gears lor 3rd,2nd,4th. reverse and 1st
(3rd gear is integral with the mainshaft, while reverse gear is integral with the 4th gear). The countershaft includes the 3rd
clutch and gears for 3rd,2nd, 4th, reverse, 1st, and park. Reverse and 4th gears can be locked to the countershaft at its cen-
ter, providing 4th gear or reverse, depending on which way the selector is moved. The sub-shaft includes the lst-hold
clutch and gears for lst and 4th.
The gears on the mainshaft are in constant mesh with those on the countershaft and sub-shaft. When certain combinations
of gears are engaged by the ctutches, power is transmitted from the mainshaft to the countershaft to provide E, D!, tr, tr,
and E position ('97 - 98 models). and E. E, E, and E position ('99 - 00 models)'
Electlonic Control
The electronic controt system consists of the Powenrain Control Module (PCM), sensors, a linear solenoid, and four
solenoid valves. Shifting and lock-up are electronically controlled for comfortable driving under all conditions. The PCM is
located below the dashboard, under the kick panel on the passenger's side.
Hydraulic Control
The valve bodies include the main valve body, the secondary valve body, the regulator valve body, the servo body, and
the lock up valve body. They are bolted to the torque converter housing. The main valve body contains the manual valve,
the 1-2 shift valve, the 2nd orifice control valve. the CPB {Clutch Pressure Back-up) valve, the modulator valve, the servo
control valve. the relief valve, and ATF pump gears. The secondary valve body contains the 2-3 shift valve, the 3-4 shift
valve, the 3,4 orifice control valve. the 4th exhaust valve and the CPC (Clutch Pressure Control) valve. The regulator valve
bodv contains the pressure regulator valve, the torque converter check valve, the cooler relief valve, and the lock-up con-
trol valve. The servo body contains the servo valve which is integrated with the reverse shift tork, and the accumulators
The lock-up valve body contains the lock-up shift valve and the lock-up timing valve. The linear solenoid and the shift con-
trol solenoid valve Ay'B are bolted to the outside of the transmission housing, and the lock-up control solenoid valve Ay'B is
bolted to the outside of the torque converter housing. Fluid trom the regulator passes through the manual valve to the
various control valves. The clutches receive fluid from their respective feed pipes or internal hydraulic circuit
ShiftControl Mechanism
input from various sensors located throughout the vehicle determines which shift control solenoid valve the PCM will acti-
vate. Activating a shift control solenoid valve changes modulator pressure, causing a shift valve to move. This pressurizes
a line to one of the clutches. engaging that clutch and its corresponding gear. The shift control solenoid valves A and B are
controlled by the PCM.
Lock-up Mechanism
tn E! position (,97 - 98 modets) and in E position ('99 - O0 models), in 3rd and 4th, and in Del position in 3rd ('97 - 98
models) and in El position with Over,Drive (O/D) is OFF (by pressing rhe O/D switchl in 3rd ('99 - 00 models), pressurized
fluid is drained from the back of the torque converter through a fluid passage, causing the lock-up piston to be held
against the torque converter cover, As this takes place, the mainshaft rotates at the same speed as the engine crankshaft.
Together with hydraulic control, the PcM optimizes the timing of the lock-up mechanism The lock-up valves control the
range of lock-up according to lock-up control solenoid valves A and B, and the linear solenoid. When lock-up control
solenoid valves A and B activate, the modulator pressure changes. The lock-up control solenoid valves A and B and the
linear solenoid are controlled by the PCM.

valves. Shifting and lock-up are electronically controlled for comfortable driving under all conditions. The PCM is located

CAUTION:
. Put on gloves to protect your hands.
. Use seat covers to avoid damaging any surfaces.
1. To remove the windshield, first remove the:
. Rearview mirror (see page 20-28)
. Sunvisors and holders (see page 20-44l'
. Ceiling light (see section 23)
. Grab handle (see page 20-44)
. Front door trim (see page 20-41)
. Front pillar trim (see page 20-41)
. Windshield wiper arms and cowl cover (see page
20-98)
2. Remove the molding and glass brackets.
NOTE: lf removing the molding is difficult, cut the
moldlng with a utility knife.
