AOD Arlington Heights Transmission Repair photos
The Ford AOD is a classic hydraulic overdrive unit where TV cable setup, fluid pressure, leaks, and band wear have to be checked before anyone calls it a rebuild.
Send the Ford, Lincoln, or Mercury model, engine, mileage if known, fluid condition, TV cable history, and whether the AOD slips, loses overdrive, or leaks.
We diagnose the AOD as a mechanical system, not like a modern electronically controlled transmission.
No overdrive, early shifts, late shifts, flare, slipping under throttle, or delayed reverse each points to a different starting point.
We check TV cable geometry, fluid level, throttle linkage, pan material, band condition, converter behavior, leaks, cooler lines, and road-test shift timing.
Classic cars that sit through Illinois winters can develop seal leaks and stale-fluid problems before internal damage shows up.
A misadjusted TV cable can destroy an AOD quickly because line pressure is wrong under load.
If the unit is already slipping or the fluid is burnt, adjustment alone is not enough.
The estimate explains whether the answer is adjustment, leak repair, service, rebuild, or replacement.
Tell us the vehicle, engine, mileage if known, shift behavior, recent work, and whether the TV cable or carb setup was changed.
If the car is a weekend cruiser, we still check it under the conditions that cause the complaint.
We help Arlington Heights Ford, Lincoln, and Mercury owners avoid damaging an AOD with trial-and-error adjustments.
Call or text 847-393-0191 with the vehicle, engine setup, recent work, and whether overdrive, slipping, or shift timing is the concern.
