Numerous factors impact the length of time it will take a mechanic at a transmission shop to repair the system. These include:
The severity of the issue.
The type of transmission system (automatic or manual).
The vehicle model.
Typically, most transmission repairs will take a day or two. In many cases, even if the transmission on a rear-wheel drive vehicle needs to be rebuilt, you’re still looking at just one to two days. For front-wheel drive vehicles, a transmission system rebuild typically takes three to four days.
When you receive a quote for the transmission repair that your vehicle needs, the service advisor or mechanic will be able to give you a more specific time frame of exactly how long the work will take.
