Automatic transmission removal and installation applies to 1993-1995 Mazda RX7 models.

On Mazda RX7 models with anti-theft radio system, obtain code number from customer to deactivate radio anti-theft system BEFORE disconnecting negative battery cable. To deactivate radio anti-theft system, turn ignition switch to ACC position. Press SCAN and AUTO-M buttons simultaneously until “cod e” is displayed. Press SCAN and AUTO-M buttons again until 4 bars are displayed.

Use preset button No. 1 to enter first number. Use preset buttons No. 2, 3 and 4 to set other numbers. Press SCAN and AUTO-M buttons for about 2 seconds until a beep is heard. After 5 seconds, flashing “cod e” will go away and radio will operate.

Removal

1. Disconnect negative battery cable. Raise and support vehicle. Drain transmission fluid. Remove both undercovers. Remove secondary air injection pipe. Remove front exhaust pipe, heat insulator and catalytic converter. Mark drive shaft-to-differential assembly for reassembly reference.
2. Remove drive shaft. Insert plug in rear of transmission to prevent leakage. Lower vehicle. Support engine from above using proper engine support assembly. Raise vehicle. Remove front, center and rear crossmembers. Support differential with transmission jack. Remove power plant frame (beam connecting transmission to differential). Remove vacuum hose, shift rod and oil cooler lines from transmission.
3. Disconnect speed sensor. Remove starter. Disconnect neutral safety switch connector, 2 speed sensor connectors and solenoid valve connector. Remove dipstick tube. Remove all wiring harness connectors from transmission. Remove lower cover from converter housing. Using Wrench (49-0877-435), remove torque converter-to-flexplate bolts.
4. Support transmission from below using transmission jack. Remove transmission-to-engine bolts. Slowly lower transmission assembly out of vehicle.

Installation

1. To install transmission, reverse removal procedure. Use NEW bolts and nuts for power plant frame installation. Place a straightedge on flat area in left front edge of rear crossmember. Ensure straightedge passes under power plant frame bolts. Measure from top of straightedge to power plant frame. Distance should be 2.76-3.03″ (70-77 mm). If distance is not as specified, adjust power plant frame installation.
2. Torque converter is correctly seated when distance between engine mating surface of converter housing and face of converter is at least 1.16″ (30 mm). Tighten bolts to specification. Fill transmission with required amount of fluid, and check for external leaks.

5. Inspect the fingers of the diaphragm spring for wear at the release bearing contact area. See figure.
6. Inspect the surface of the pressure plate for wear, cracks, and burning.
7. Inspect for warpage using a straight edge and feeler gauge. Measure across the pressure plate. If the warpage is more than the service limit, replace the pressure plate. See figure.

• Standard (New): 0.03 mm (0.001 in.) max.
• Service Limit: 0.15 mm (0.006 in.)

8. Remove the clutch disc and special tools. See figure.
9. Inspect the lining of the clutch disc for signs of slippage or oil. If the clutch disc looks burnt or is soaked with oil, replace it. Find the source of the oil leak if the clutch disc is soaked.
10. Measure the clutch disc thickness. If the thickness is less than the service limit, replace the clutch disc. See figure.

• Standard (New): 8.2-8.9 mm (0.32-0.35 in.)
• Service Limit: 6.0 mm (0.24 in.)

11. Measure the rivet depth from the clutch disc lining surface to the rivets, on both sides. If the rivet depth is less than the service limit, replace the clutch disc. See figure 1 of 2. See figure 2 of 2.

5. Align the hole in the flywheel with the crankshaft dowel pin, and install the flywheel. Install the washer and mounting bolts, finger-tight.
6. Install the special tool, then torque the flywheel mounting bolts in a crisscross pattern in several steps. See figure.

Release Bearing Inspection

Check the play of the release bearing by spinning it with your hand, if there is excessive play, replace the release bearing with a new one. See figure.

The release bearing is packed with grease. Do not wash it in solvent.

Clutch Disc and Pressure Plate Installation

1. Apply a thin, uniform coat of super high temp urea grease (PN 08798-9002) to the splines of the clutch disc. Slide the clutch disc onto the mainshaft, and remove extra overflow grease.

The delay orifice mechanism improves clutch operation by delaying the slave cylinder release speed when the clutch pedal is suddenly released. The delay orifice mechanism is built into the slave cylinder.

When the clutch pedal is pressed, the fluid pressure from the master cylinder moves the one-way valve in the direction shown in the illustration. The fluid flows through two passages: the orifice part and the filter part. It then flows out to the slave cylinder to release the pressure plate and clutch disc joint.

When the clutch pedal is released, the fluid pressure from the slave cylinder moves the one-way valve in the direction shown in the illustration. The one-way valve blocks the filter-part passage and delays the clutch release speed by returning the fluid to the master cylinder through only the orifice-part passage.

Clutch pedal adjustment applies to Honda S2000 1999-2003 models.

• Check the clutch pedal position switch.
• Check the clutch interlock switch.
• The clutch is self-adjusting to compensate for wear.
• If there is no clearance between the master cylinder piston and pushrod. The release bearing will be held against the diaphragm spring, which can result in clutch slippage or other clutch problems.

1. Loosen the locknut, and back off the clutch switch until it no longer touches the clutch pedal.
2. Loosen the locknut, and turn the pushrod in or out to get the specified height and stroke at the clutch pedal.

• Clutch Pedal Stroke: 115-125 mm (4.53-4.92 in.)
• Clutch Pedal Height: 189 mm (7.44 in.)

3. Tighten the locknut .
4. With the clutch pedal released, turn in the clutch pedal position switch until it contacts the clutch pedal.
5. Turn in the clutch pedal position switc an additional 3/4 to 1 turn.
6. Tighten the locknut.
7. Loosen the locknut and the clutch interlock switch.
8. Press the clutch pedal to the floor.
9. Release the clutch pedal 15-20 mm (0.59-0.79 in.) from the fully pressed position, and hold it there. Adjust the position of the clutch interlock switch so the engine will start with the clutch pedal in this position.
10. Tighten the locknut.

Honda S2000 F20C VTEC solenoid applies to 1999-2003 AP1 models.

1. Disconnect the 1P connector from the VTEC solenoid valve.
2. Measure resistance between the terminal and body ground.
   • Resistance: 14-30 ohm



3. If the resistance is within specifications, remove the VTEC solenoid valve assembly from the cylinder head, and check the VTEC solenoid valve filter for clogging. If there is clogging, replace the engine oil filter, VTEC solenoid valve filter, and the engine oil.
   
4. If the filter is not clogged, push the VTEC solenoid valve with your finger and check its movement. If the VTEC solenoid valve is normal, check the engine oil pressure.
