Transmission System Overview

The Fordomatic automatic transmission system features three-speed automatic operation with torque converter, planetary gear sets, hydraulic control system, and electronic controls.

Component	Description
Torque Converter	Hydraulic coupling providing torque multiplication
Planetary Gear Sets	Multiple gear sets for forward and reverse operation
Hydraulic Control System	Valve body and hydraulic circuits for gear selection
Electronic Controls	Transmission control module and sensors
Oil Pump	Provides hydraulic pressure for operation
Clutch Packs	Multiple friction discs for gear engagement
Bands	Steel bands for gear holding
Output Shaft	Transmits power to drive wheels
Transmission Cooler	Maintains proper fluid temperature
Shift Linkage	Mechanical connection to shift selector

Maintenance Procedures

Regular maintenance ensures optimal transmission performance and longevity.

Fluid Change: Drain and refill transmission fluid every 30,000 miles.
Filter Replacement: Replace transmission filter during fluid service.
Band Adjustments: Adjust bands per specified procedures and intervals.
Linkage Adjustment: Verify and adjust shift linkage for proper operation.

WARNING! Transmission fluid is hot during operation; allow to cool before servicing. Use proper lifting equipment when working under vehicle.

Diagnostic Procedures

Systematic diagnosis identifies transmission problems accurately.

Road Test: Evaluate shift quality, timing, and converter operation.
Fluid Inspection: Check fluid level, color, and condition for clues.
Pressure Testing: Measure line pressure at various operating conditions.
Electronic Diagnosis: Scan for trouble codes and test sensors/actuators.

CAUTION! Always use transmission jack when removing/installing transmission. Secure vehicle properly on lift or stands.

Planetary Sets: Front and rear planetary gear assemblies. Governor: Mechanical governor for shift timing. Accumulators: Cushion shift engagement.

Fluid Requirements

Proper fluid selection and maintenance critical for transmission longevity.

Use only Dexron II/Mercon automatic transmission fluid.
Check fluid level with engine running at operating temperature.
Fluid should be red in color; brown or black indicates need for service.
Replace fluid if burnt odor detected.

Tip: Always clean dipstick area before checking fluid to prevent contamination.

Repair Procedures

Step-by-step instructions for common transmission repairs.

Transmission Removal: Disconnect linkages, cooler lines, and driveshaft before removal.
Valve Body Service: Remove, clean, and inspect valve body components.
Clutch Pack Replacement: Measure clutch clearances and replace worn components.
Band Adjustment: Adjust bands to specified torque and clearance.
Seal Replacement: Replace all seals during reassembly.
Torque Converter: Inspect converter for damage; replace if necessary.
Reassembly: Follow specific torque sequences and clearances.
Initial Operation: Check fluid level and test operation after installation.

WARNING! Always use new gaskets and seals during reassembly. Verify proper fluid level before operation.

Torque Specifications

Critical fasteners require specific torque values for proper operation.

Component	Torque Value

Troubleshooting Guide

Symptom	Possible Cause	Corrective Action
No forward movement	Low fluid, forward clutch failure	Check fluid level; test line pressure; inspect forward clutch
No reverse	Reverse band, low reverse servo	Adjust reverse band; check reverse servo operation
Delayed engagement	Low fluid, filter clogged, pump wear	Check fluid and filter; test pump pressure
Slipping in gear	Worn clutches, low pressure	Test line pressure; inspect clutch packs
Harsh shifting	Valve body, accumulator, pressure	Check valve body; test accumulator; adjust pressure
No upshift	Governor, valve body, throttle valve	Test governor operation; inspect valve body
Overheating	Cooler restriction, heavy use	Check cooler flow; reduce load conditions
Fluid leaks	Seals, gaskets, loose fittings	Identify leak source; replace seals/gaskets

Note: Always verify basic items (fluid level, linkage adjustment) before major disassembly.
