Automatic Gearbox

What is a Automatic Gearbox?
An automatic gearbox (transmission) is a gearbox designed to select the appropriate gear ratio automatically with no driver input. There are many types of automatic gearbox with different characteristics but they all have the same objective, to manage the gear ratios for the driver.

How much does it cost to replace the Automatic Gearbox?
The cost of a replacement automatic gearbox is dependent on the car make and model, the prices vary widely but you can expect the cheapest brand new gearbox to cost over £1000.

It's unusual that you'd need to replace the entire gearbox as more often than not the gearbox can be repaired, so you're more likely to have it rebuilt with replaced parts than to replace it entirely. The labour cost can be high when having a rebuild but it will still be cheaper than a replacement automatic gearbox.

A cheaper alternative to a brand new OEM replacement gearbox is a refurbished unit, these can be picked up from around £400 (for something like a Ford Focus). This is definitely the way to go if you're dealing with an older car that has no warranty. You'll often get a decent warranty from the supplier too so a bit of extra peace of mind.
