What you are looking at

No photograph available

We do not hold a verified photograph for this fault yet. We would rather show none than show a picture of something else.

What goes wrong

The Getrag MT82 6-speed manual fitted to V8 and EcoBoost Mustangs has extensively documented synchroniser wear in 1st and 2nd gear. The unit uses a single-cone synchro design inadequate for the torque output of the 5.0 V8. Symptoms appear from 50,000 km and worsen progressively. Ford issued TSB 12-12-4 and later revised fluid specifications, but the underlying design weakness remained. Documented by Mustang communities in the US, UK, and Australia.

What you would notice

Notchy or crunching shift into 1st or 2nd gear, especially when cold
Grinding on aggressive 1-2 shift under load
Difficulty selecting 1st from rest
Synchro crunch on downshift into 2nd

How to check it

Where to look. MT82 gearbox, centre tunnel

Test cold and warm shifting through all gears, focusing on 1st-2nd.
Crunch or notchiness on cold gearbox is a near-certain indicator of synchro wear.
Check fluid – should be Motorcraft Full Synthetic Manual Transmission Fluid per revised spec.

What it costs to put right

$2,200 to $5,500 at New Zealand independent workshop rates. That is for this job on its own, not for the car.

An estimate, in NZD, for the repair as normally carried out. What a specific car costs depends on which part has failed and what it damaged on the way — treat this as the floor for a negotiation, not a quote.

Ask the seller

“Has the transmission fluid been changed to Motorcraft full synthetic?”
“Any grinding or difficulty shifting into 1st or 2nd gear?”

What it does not tell you is whether THIS car has been looked after: its odometer history and whether the reading has ever gone backwards, whether there is still money owing on it, whether it has been reported stolen, how many owners it has had and what it is really worth today.

How much does it cost to fix on a Ford Mustang?

$2,200 to $5,500 at New Zealand independent workshop rates. That figure is for this job on its own. A car showing the symptoms on this page is usually worth either walking away from or negotiating down by at least the repair figure.

Which Ford Mustang years are affected?

Our research records this fault on the 2011–2017 Ford Mustang.
