Overhaul - Ax4S/AXOD-E: Description
The AXOD-E combines an automatic transaxle and differential into a single unit designed for front wheel drive vehicles. The transaxle is an electronically controlled, fully automatic unit with 4 forward speeds, one Reverse, Neutral and Park. Shift control solenoids provide gear selection and are controlled by the EEC-IV microprocessor. For additional information on the EEC-IV system, see appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
The AXOD-E has 2 planetary gear sets and a combination planetary/differential gear set. Four multiple-plate clutches, 2 band assemblies, and 2 roller (one-way) clutches act as friction elements for operation of the planetary gear sets. See Fig 1 .
A lock-up torque converter couples the engine output to the planetary gears and overdrive unit. This is done by a chain which connects the drive and driven sprockets. The converter lock-up is controlled through the EEC-IV system. A piston plate clutch, inside converter, is activated by the computer and valve body.
