TRANSMISSION APPLICATION
IDENTIFICATION
Identification plate is located on side of transmission case. (Scheme 1) Identification plate information may be required when ordering replacement components.
Scheme 1
DESCRIPTION & OPERATION
Note. The transmission electronic control system is controlled by Powertrain Control Module (PCM). In this article, this unit will be referred to as "control module".
Automatic transmission is electronically controlled, providing 4 forward speeds and one reverse speed. Transmission consists of a torque converter, clutches, planetary gears and brake band. (Scheme 2) On 4WD models, transfer case is bolted to rear of transmission.
Transmission shifting and torque converter lock-up are controlled by the control module. The control module receives information from various input devices and uses this information to control shift solenoids, band apply solenoid and Torque Converter Clutch (TCC) solenoid. The control module uses input signals to control the force motor solenoid operation, which activates the pressure regulator valve for controlling the line pressure.
A torque management control system is used to reduce engagement shock caused by a change in vehicle speed during shifting. For additional information on the electronic control system, see appropriate ELECTRONIC CONTROLS article.
The control module contains a self-diagnostic system which stores a Diagnostic Trouble Code (DTC) if a specified failure or problem is present in the transmission electronic control system. If fault has set a DTC, the CHECK TRANS light on instrument panel will flash. The DTC may be retrieved to determine transmission problem area. For additional information on self-diagnostic system, see appropriate ELECTRONIC CONTROLS article.
Transmission is capable of 3 different shift modes, Normal (NOR) mode, Power (PWR) mode and Winter mode. Shift mode may be selected by POWER or WINTER mode switch mounted on center console, near gearshift lever. Shift modes are used to change transmission shift points for various vehicle operating conditions. For additional information on shift modes, see appropriate ELECTRONIC CONTROLS article.
The control module contains a fail-safe system. When a failure or problem is present in the transmission electronic control system, the control module may go into a back-up mode using pre-programmed values, allowing vehicle to be driven. The CHECK TRANS light on instrument panel will flash to inform driver of a problem. Vehicle can be driven, but shifting must be done manually. When manually shifting transmission, if shift lever is placed in "D" or "3" position, transmission remains in 4th gear. If shift lever is placed in "2" position, transmission remain in 3rd gear. If shift lever is placed in "L" position, transmission remains in 1st gear. If shift lever is placed in "R" position, transmission will shift into reverse.
Transmission is equipped with shift and key lock systems. Shift lock system prevents gearshift lever from being moved from "P" position unless brake pedal is depressed, ignition is on and release button on gearshift lever is depressed. For additional information on shift lock system, see appropriate ELECTRONIC CONTROLS article.
Key lock system prevents ignition switch from being placed in LOCK position unless gearshift lever is in "P" position. Shift lock cable is connected between gearshift lever and ignition switch. When gearshift lever is placed in "P" position, shift lock cable moves lock on ignition switch so ignition switch may be placed in LOCK position.

ELECTRICAL COMPONENTS
For servicing of electrical components, see appropriate ELECTRONIC CONTROLS article.
BRAKE BAND ADJUSTMENT
- Drain fluid. Remove bolts, main case oil pan and gasket. (Scheme 7) Remove bolts, servo cover and gasket. Loosen lock nut on servo adjusting screw.
- Using an INCH-lb. torque wrench, tighten servo adjusting screw to 40 INCH lbs. (4.5 N.m). Back off servo adjusting screw 5 revolutions. Hold sleeve on servo piston. Tighten lock nut to 14 ft. lbs. (19 N.m). Ensure servo adjusting screw does not rotate while tightening lock nut.
- Using a NEW gasket, install servo cover. Install and tighten bolts to specification. See «TORQUE SPECIFICATIONS»(/acura/slx/i-1995-1999/remont/automatic-trans/#automatic-transmission-overhaul-4l30-e__torque-specifications). Using a NEW gasket, install main case oil pan. Install and tighten bolts to specification. Fill transmission with Dexron-III ATF.
SHIFT LOCK CABLE ADJUSTMENT (EXCEPT 1998 RODEO)
Key lock system prevents ignition switch from being placed in LOCK position unless gearshift lever is in "P" position. Shift lock cable is connected between gearshift lever and ignition switch. When gearshift lever is placed in "P" position, check that ignition switch may be placed in LOCK position. If ignition switch cannot be placed in LOCK position, perform the following shift lock cable adjustment
- Place ignition switch in LOCK position. Ensure gearshift lever is in "P" position. Remove console components for access to shift lock cable at gearshift lever.
- Adjust cable screw cap on gearshift lever side of shift lock cable to provide slack in shift lock cable so a gap of.039-.079" (0.9-2.01 mm) exists between rod on steering lock side and the stopper. (Scheme 3)
- Tighten lock nut "A" against bracket while pulling cable screw cap toward instrument panel side (front) of center console. (Scheme 3) This prevents slack in the inner cable.
- Loosen lock nut "A" 2 turns to provide slack in inner cable. Hold lock nut "A" and tighten lock nut "B" to 35 INCH lbs. (4 N.m). To recheck system operation, ensure gearshift lever cannot be moved from "P" position with ignition switch in LOCK position.
- Ensure ignition switch can be turned to LOCK position only when gearshift lever is in "P" position. If operation is not as specified, readjust shift lock cable.
Scheme 3
SHIFT LOCK CABLE ADJUSTMENT (1998 RODEO)
Key lock system prevents ignition switch from being placed in LOCK position unless gearshift lever is in "P" position. Shift lock cable is connected between gearshift lever and ignition switch. When gearshift lever is placed in "P" position, ensure ignition switch may be placed in LOCK position. If ignition switch cannot be placed in LOCK position, perform the following shift lock cable adjustment
- Place ignition switch in LOCK position. Ensure gearshift lever is in "P" position. Remove console components for access to shift lock cable at gearshift lever.
- Disconnect cable adjustment lock on outer cable at mounting bracket noting position for installation. Pull outer cable rearward to check motion. Reconnect cable adjustment lock.
- Check system operation as follows: Gear selector should not move out of "P" with ignition switch in LOCK position. Gear selector should move out of "P" with ignition switch in ON only when brake pedal is pressed. Ignition switch can only be moved to LOCK when gear selector is in "P". If conditions are not as specified, readjust shift lock cable or check connector wiring and brake switch operation.

TRANSMISSION TESTING
Note. Before beginning any testing, check fluid level, fluid condition and shift linkage adjustment. Check for any stored diagnostic trouble codes. See RETRIEVING DIAGNOSTIC TROUBLE CODES under SELF-DIAGNOSTIC SYSTEM in appropriate ELECTRONIC CONTROLS article.
ROAD TEST
Note. If road test is performed with engine coolant temperature less than 158°F (70°C), shift speeds will be delayed during light throttle application and occur at a slightly higher speed. When TECH 1 scan tool is connected to data link connector, maximum line pressure will be obtained, resulting in harsh shifts.
Note. Engine coolant temperature must be greater than 158°F (70°C) for TCC operation. The TCC operates in 2nd gear kickdown when engine coolant temperature is greater than 158°F (70°C). TCC operates in 2nd, 3rd and 4th gear when transmission fluid temperature is greater than 284°F (140°C).
- If a stored diagnostic trouble code is present, clear diagnostic trouble codes from control module memory. See CLEARING DIAGNOSTIC TROUBLE CODES under SELF-DIAGNOSTICS SYSTEM in appropriate ELECTRONIC CONTROLS article.
- Start and warm engine to normal operating temperature. Road test vehicle and check for abnormal noise, clutch slippage and shift firmness. Specified clutch and brake are applied in designated gear. See «CLUTCH & BAND APPLICATION»(/acura/slx/i-1995-1999/remont/automatic-trans/#automatic-transmission-overhaul-4l30-e) table.
- Ensure upshift and downshift speeds are correct in relation to throttle opening and position of POWER or WINTER mode switches mounted on center console, near gearshift lever. See appropriate UPSHIFT SPECIFICATIONS and DOWNSHIFT SPECIFICATIONS tables.
- Ensure Torque Converter Clutch (TCC) operation is correct to gear application in relation to throttle opening with shift lever in "D" position. See appropriate TCC SPECIFICATIONS table under «TRANSMISSION TESTING»(/acura/slx/i-1995-1999/remont/automatic-trans/#automatic-transmission-overhaul-4l30-e__transmission-testing).
- During road test, if CHECK TRANS light on instrument panel starts flashing, a DTC is stored in control module memory. Check stored diagnostic trouble code and repair as necessary.
- During road test, if a problem is present, but CHECK TRANS light on instrument panel did not flash, turn engine off. Disconnect control module harness connectors. (Scheme 4)
- Repeat road test, while manually shifting the transmission. With shift lever in "L" position, transmission should remain in 1st gear. With shift lever in "2" position, transmission should remain in 3rd gear. With shift lever in "3" or "D" position, transmission should remain in 4th gear. Shut engine off. Reconnect control module harness connectors.
- If problem is still present, see «SYMPTOM DIAGNOSIS»(/acura/slx/i-1995-1999/remont/automatic-trans/#automatic-transmission-overhaul-4l30-e) under TROUBLE SHOOTING. If problem is not present with harness connectors disconnected at control module, check wiring connections and control module ground circuits.
