=====''Mazda RX-7 Automatic Transmission Overhaul Part 1: road test results, stall speed and more ''=====
**CAUTION:** Disconnecting battery on models equipped with [[AntiTheftSystemFD3S anti-theft]] radio require canceling of anti-theft operation. Refer to vehicle owner's manual to identify radio type.
Transmission model number is identified by a stamped metal plate attached to left or right side of rear transmission housing. See Fig. 1.
TCM receives information from various input devices and uses this information to control [[TestingCodes2FD3S solenoids]] for transmission shifting, line pressure, shift feel and torque converter clutch lock-up.
Possible causes: low [[ATServicingFD3S ATF level]], selector lever adjustment, faulty or misadjusted TP sensor, low line pressure, internal transmission slippage, faulty valve body, faulty pressure control solenoid, faulty dropping resistor, worn shift solenoids "A" and/or "B", misadjusted transmission range switch, faulty [[SteeringColumnSwitchesFD3S HOLD switch]], faulty output speed sensor, worn torque converter and/or low engine output.
Possible causes: worn shift solenoids "A" and or "B", misadjusted transmission range switch, faulty HOLD switch, faulty output speed sensor, faulty valve body, poor ground and/or faulty TCM.
Possible causes: faulty TFT sensor, worn shift solenoids "A" and/or "B", worn overrunning clutch solenoid, faulty valve body, misadjusted transmission range switch, faulty output speed sensor, faulty 4th gear inhibit signal, shorted DLC connector TAT terminal, faulty [[SteeringColumnSwitchesFD3S HOLD switch]], poor ground and/or faulty TCM.
Possible causes: low [[ATServicingFD3S ATF level]], poor ground, misadjusted TP sensor, faulty output speed sensor, faulty TCM and/or faulty valve body.
Possible causes: worn TCC [[TestingCodes2FD3S solenoid]], worn TCC control solenoid, faulty valve body, faulty TFT sensor,misadjusted TP sensor, faulty closed throttle position switch, faulty engine RPM signal, faulty output speed sensor and/or faulty transmission range sensor.
Possible causes: low ATF level, internal component failure, faulty pressure control [[TestingCodes2FD3S solenoid]], faulty or misadjusted TP sensor, faulty dropping resistor, worn TCC solenoid, worn TCC control solenoid and/or fluid cooling system.
Check all [[ATServicingFD3S fluid levels]] and correct if necessary. Warm engine and transmission to operating temperature. Prior to performing stall test, block front and rear wheels and set parking brake.
1. Connect gauges to appropriate line pressure inspection ports. See Fig. 11. Connect tachometer to engine. Ensure engine idle speed and ignition timing is correct.
Fluid leakage from [[FusesandCircuitBreakersFD3S hydraulic circuit]] of reverse clutch.
Throttle sensor out of adjustment. Damaged thermosensor. Line pressure solenoid sticking. Short circuit of line pressure [[TestingCodes2FD3S solenoid]] circuit. Pressure modifier valve sticking. Pressure regulator valve or plug sticking.
