Transmission Fault and Adaptation Data
Modern boxes log clutch fill times, slip, line pressure and temperature. Those values say whether the box is worn, whether it has adapted around a fault, or whether the problem sits outside it entirely.
A conventional automatic on much of the range and an automated manual transaxle on some, and they could not be more different. Al Zaabi Autocare carries out Aston Martin gearbox and transmission repair in Mussafah, Abu Dhabi, across the DB11, DBS, Vantage, DBX and Rapide.

Gearboxes are expensive to guess at. The work starts with what the transmission itself reports, then with fluid, and only then with the box.
Open the full list below for everything a Aston Martin gearbox repair covers, and what each part of it involves.
Modern boxes log clutch fill times, slip, line pressure and temperature. Those values say whether the box is worn, whether it has adapted around a fault, or whether the problem sits outside it entirely.
Burnt or low fluid causes most of the symptoms owners bring in. Level is set at the manufacturer's fluid temperature, because at any other temperature the reading means nothing.
Shift quality is judged warm, on the road, through the range the fault appears in, with live data recording alongside. A gearbox that behaves in the workshop tells you nothing.
A great many faults that feel like a failing gearbox are hydraulic or electrical control. Solenoids, pressure regulators, sleeves and wiring are repaired without opening the gear set.
Judder from rest and slip under load are measured against clutch wear data rather than assumed. On a dual clutch that data is the difference between an adaptation and a clutch.
Shudder at light throttle at cruising speed is usually lock-up clutch material rather than the gearbox, and it is tested for as its own fault.
Correct fluid, new filter, pan and magnets cleaned, sealed and filled to the temperature specification. Done properly it is one of the cheapest things you can do for a gearbox.
Where the box comes out it is stripped, measured and rebuilt with new clutches, seals, bearings and bushes to specification, then bench tested before it goes back in.
On four-wheel drive cars a bind or a whine is as likely to be the transfer case, a coupling or a differential as the gearbox, and all three are checked with it.
After any transmission work the adaptations are reset and driven in, so shift quality settles where the manufacturer intended instead of around the fault that has just been fixed.
A gearbox is expensive to guess at. These are the faults worth ruling in or out before anybody talks about a rebuild.
The automatics are strong and sensitive to fluid, and in this heat it ages faster than any schedule assumes. The level is set at the correct fluid temperature.
On the automated manual cars, clutch wear and the actuator are read on their own data. Slow shifts and slip are usually one of those rather than the gear set.
Where the gearbox sits at the back, its oil and its mounts are their own service items, and a vibration blamed on the box is often a mount or a propshaft.
A vibration at a light throttle cruise is the lock-up clutch and is cheapest caught while it is occasional.
Adaptations are reset and driven in after any work so shift quality returns rather than settling around the old fault.
Read, test, quote, repair, relearn.
Fault memory, adaptation values and a road test under load, so the symptom is matched to data rather than to an opinion.
The findings and the options: control repair, fluid service, clutch work or rebuild, each priced, before anything is removed.
Carried out to specification with the correct fluid and the correct fill procedure, which on most modern boxes matters as much as the parts.
Adaptations reset and driven in, then a second road test through the range that showed the fault.
What you drive away with after a Aston Martin gearbox repair, beyond the invoice.
Gears that arrive when they should and without the thump, because the cause was found rather than the symptom adapted around.
The fault that made the transmission protect itself is gone, so the car stops dropping into third on the motorway.
Control, fluid and clutch faults are told apart from wear before anything is quoted, which is what stops a mechatronic fault being sold as a gearbox.
The specification the box was designed around, filled at the right temperature. Most gearbox trouble that comes back is a fill that was close enough.
The box relearns from a clean start rather than carrying the settings it built up while the fault was there.
The data before, the work done and the data after, so the next person to look at the car is not starting from nothing.

A gearbox gives plenty of warning. What it does not give is a second chance once it has run low on fluid.
A shift that takes a moment to arrive, most noticeable pulling away or on a light throttle upshift.
The shift arrives all at once, or the revs rise between gears. Both are clutch or pressure faults and both get worse.
Revs rise and the car does not follow. That is clutch material going, and every kilometre driven on it destroys more of what is left.
A vibration at steady cruising speed, usually the torque converter lock-up clutch, and far cheaper to deal with early.
A whine that changes with road speed rather than engine speed points at bearings, the transfer case or a differential.
The transmission has logged something serious enough to protect itself. It should be read before the car is driven further.
A pause before drive or reverse takes up, worst when cold, which is usually pressure rather than the gear set.
Fluid that smells burnt has been overheated, and overheated fluid stops protecting the clutches it is carrying.

What Aston Martin owners ask before booking a gearbox repair in. If yours is not here, call the workshop and ask.
Not necessarily. On those cars the clutch, the actuator and the hydraulics all produce jerky shifts and cost very differently. The data separates them before anything comes out.
Yes, and sooner here than the schedule implies. Heat ages the fluid, and correct fluid at a correct level is the cheapest protection the box will ever get.
It is described that way and it is not how these boxes behave in this climate. Heat is what ages the fluid, and a service with the correct fluid and a properly set level is one of the cheapest things you can do for a gearbox that is still healthy.
Sometimes. Slip caused by pressure, a solenoid or a control fault is repaired without opening the gear set. Slip caused by clutch material that has gone is not. The data says which before the box comes out.
The valve body and its electronics together: the part that decides and delivers every gear change. A great deal of what feels like a failing gearbox is a fault in it, and it is a very different job from a rebuild.
A gearbox learns around wear and around faults. If the old settings are left in place after a repair, the box keeps compensating for a problem that is no longer there, and the shift quality never comes back properly.
