Toyota OEM Transmission Control Module (TCM) 89530-02010 — Aisin — 4A-GE AE82 Corolla FX16 GT-S Automatic

Genuine Toyota Aisin automatic transmission control module (TCM/ECU), part #89530-02010. This is the factory computer that manages shift timing and lock-up for the electronically controlled automatic transaxle on the 4A-GE-powered Corolla.

Original Toyota / Aisin unit with the factory "TRANSMISSION CONTROL — AISIN" and 89530-02010 labeling — not an aftermarket or refurbished substitute. It mounts under the dash near the shifter (see factory diagram, position 89530). A faulty TCM is a common cause of harsh shifting, failure to shift, stuck-in-gear conditions, or erratic automatic behavior, so a correct OEM replacement is often the fix when the transmission itself is mechanically sound.

Fitment:

• Toyota Corolla FX16 GT-S (AE82) — 4A-GE 1.6L, automatic transmission
• Related E80-chassis 4A-GE automatic applications using 89530-02010

Condition: Used OEM unit, removed from vehicle. (See note below — let me know the tested status so I can finalize this line.)

Returns: Backed by our 30-day return policy.

Please confirm your original module is 89530-02010 before ordering — transmission control modules are calibration-specific and vary by chassis, engine, and transmission, so the part number must match exactly.
