Automatic Transmission Overhaul - s4xa Acura Integra III

APPLICATION

TRANSAXLE APPLICATIONS

IDENTIFICATION

Transaxle model and serial number are stamped on the transaxle. (Scheme 54) Model and serial number may be required when ordering replacement components.

Scheme 54

DESCRIPTION

Automatic transaxle provides 4 forward speeds and one reverse. Transaxle consists of clutches, mainshaft, countershaft, sub-shaft, shift control solenoid valves, lock-up control solenoid valves and lock-up torque converter. (Scheme 55)

Valve bodies consists of main valve body, secondary valve body, servo body, lock-up valve body and regulator valve body. Valve bodies are attached to torque converter housing. Transaxle shifting and torque converter lock-up are controlled by the Transmission Control Module (TCM).

The Throttle Valve (T.V.) is controlled by a throttle cable. Throttle cable adjustment is essential for proper operation of transaxle. Misadjustment not only affects the shift points but also the shift quality and lock-up clutch operation. If cable is adjusted too long, it will result in throttle pressure being too low for the amount of engine torque input into transaxle and may cause clutch slippage. A cable adjusted too short will result in too high throttle pressure which may cause harsh shifts, erratic shifts and torque converter hunting.

Scheme 55

OPERATION

When in "D" position in 3rd gear or "D4" position in 2nd, 3rd or 4th gear, torque converter lock-up exists and transaxle mainshaft rotates at the same speed as engine crankshaft. Under certain conditions, torque converter lock-up clutch is applied during deceleration when in 3rd and 4th gears. Torque converter lock-up is controlled by the TCM. The TCM receives various input signals and operates lock-up control solenoid valves. Operation of lock-up control solenoid valves controls the modulator pressure.

The TCM contains a grade logic control system which controls transaxle shifting while vehicle is ascending or descending on a slope or reducing vehicle speed. For more information on grade logic control system, see ACURA S4XA ELECTRONIC CONTROLS article.

The Throttle Valve (T.V.) is controlled by a throttle cable. If cable is adjusted too long, it will result in throttle pressure being too low for the amount of engine torque input into transaxle and may cause clutch slippage. A cable adjusted too short will result in too high throttle pressure which may cause harsh shifts, erratic shifts and torque converter hunting.

The TCM contains self-diagnostic system, which stores Diagnostic Trouble Code (DTC) if failure or problem exists in transaxle electronic control system. The DTC code can be retrieved to determine transaxle problem area. For information on electronic transaxle components, see ACURA S4XA ELECTRONIC CONTROLS article.

Transaxle is equipped with shift and key interlock systems. Shift interlock system prevents shift lever from being moved from "P" position unless brake pedal is depressed and accelerator pedal is in idle position. In case of a malfunction, shift lever can be released by placing ignition key in release slot near shift lever. Key interlock system prevents ignition key from being removed from ignition switch unless shift lever is in "P" position. For additional information on interlock systems, see ACURA/HONDA SHIFT INTERLOCK SYSTEMS article.

The A/T gear position indicator contains lights to indicate which position A/T gear position switch on shift lever is in. For information and testing of A/T gear position indicator, see ACURA S4XA ELECTRONIC CONTROLS article.

Shift lever has 7 positions. When shift lever is moved, manual valve on main valve body is moved by the shift cable. When certain transaxle gear combinations are engaged by clutches, power is transmitted from the mainshaft to the countershaft through the sub-shaft to provide different gears. Shift lever positions operate as follows.

"P" (Park)

Front wheels locked as parking pawl engages with parking gear on countershaft. All clutches are released. Neutral position switch, incorporated in A/T gear position switch, allows engine starting in this position.

"R" (Reverse)

Reverse selector engages with countershaft reverse gear and 4th gear clutch is applied. Backup light switch, incorporated in A/T gear position switch, allows back-up lights to operate.

"N" (Neutral)

All clutches are released. Neutral position switch, incorporated in A/T gear position switch, allows engine starting in this position.

"D4" (Drive/4th Gear)

Transaxle starts in 1st gear and upshifts automatically to 2nd, 3rd and 4th gears. Transaxle will downshift through 3rd, 2nd and 1st gears until vehicle stops. When in 2nd, 3rd or 4th gear in "D4" position, TCM sends signal to operate torque converter lock-up.

"D" (Drive/3rd Gear)

Transaxle starts off in 1st gear and upshifts automatically to 2nd gear and 3rd gear. On deceleration, transaxle will downshift through 2nd gear to 1st gear. When in 3rd gear in "D" position, TCM sends signal to operate torque converter lock-up.

"2" (Second Gear)

Transaxle starts off and remains in 2nd gear for engine braking and better traction.

"1" (First Gear)

Transaxle starts off and remains in 1st gear for engine braking.

OIL COOLER FLUSHING

1. Attach Oil Cooler Flusher (J38405-A) to oil cooler lines. (Scheme 56) Fill oil cooler flusher tank 2/3 full with Flushing Fluid (J35944-20). DO NOT use any other flushing fluid.
2. Ensure water and air valves on oil cooler flusher are off. Apply 80-120 psi (550-829 kPa) air pressure to oil cooler flusher. Turn oil cooler flusher water valve on so water will flow through oil cooler for 10 seconds. Shut water valve off. Replace oil cooler if water will not flow through oil cooler.
3. Depress and hold mixing trigger on oil cooler flusher downward. Turn water valve on and flush oil cooler for 2 minutes. Turn air valve on for 5 seconds every 15-20 seconds to create a surging action.
4. Turn water valve off. Release mixing trigger. Disconnect oil cooler flusher and reverse hoses so oil cooler can be flushed in the opposite direction.
5. Repeat steps 2 and 3. Turn water valve off. Release mixing trigger. Turn water valve on and rinse oil cooler for at least one minute. Once oil cooler is flushed in both directions, turn water off. Turn air valve on for 2 minutes or until no moisture is visible from drain hose. CAUTION: Ensure no moisture exists in oil cooler, as it can damage transaxle.
6. Turn air off. Disconnect oil cooler flusher. Reconnect inlet line on oil cooler. Once transaxle is installed, attach drain hose on return line and place in oil container. Ensure transaxle is in "P" position. Fill transaxle with Dexron-II ATF.
7. Start engine and operate for about 30 seconds or until one quart (.9L) of ATF is discharged from return line. Turn engine off. Remove drain hose. Reinstall return line. Fill transaxle to proper level.
