Component Disassembly and Reassembly

This 100-page publication details the systematic teardown and rebuild of the Toyota A-131L and A-132L automatic transaxle systems. The text documents the internal arrangement of the torque converter, oil pump, planetary gear sets, forward and direct clutches, and the control valve assembly. Descriptive chapters outline the proper extraction of the governor, oil strainer, valve body components, and individual clutch assemblies. The content provides the necessary clearance data for side gears, pinion gears, and clutch piston strokes required for a high-precision build.

Specification Highlights

Technical data previews include critical settings for hydraulic pressure tests, shift speed ranges, and torque converter stall speeds. For instance, the differential side gear backlash is specified at.002–.008 mm in the assembly data. The direct clutch piston stroke is documented at.054–.067 inches for proper clearance control. The forward clutch disc soaking requirement is explicitly noted as a minimum of 15 minutes in ATF. These values are extracted directly from the factory tables to provide reliable benchmarks during the assembly of these three-speed transaxles.

This 100-page OEM technical manual covers the 1984–1994 Toyota Tercel, Corolla, Geo Prizm, and Chevrolet Nova, providing full internal rebuild specifications for the A-131L and A-132L automatic transaxle systems.
