What Happens During a Car Transmission Repair

It’s hard to know when your car transmission needs repairing until you’re faced with that frustrating “Check Engine” light. The gearbox is one of the most complex mechanisms inside a vehicle, so it’s worth knowing what to expect before you head into the garage. Here are the nine procedures that may occur during a transmission repair.

1) Diagnosis

The transmission control unit is located inside the transmission, and, as the name suggests, it controls how the gearbox operates. Replacing this component is one of the common repairs required to fix a problem.

2) Sourcing replacement parts

Once your mechanic has determined what part needs replacing and details like where it’s located, they’ll have to find a replacement. This is usually sourced from the same manufacturer that makes the original component. 

3) Changing transmission fluid

The level of transmission fluid used in your car is controlled by your “transmission control unit,” and it must be changed regularly to ensure that the gears are fully lubricated.

4) Re-installing parts

“Re-installing” is a term that applies to both parts for the automatic transmission and their respective mounting brackets. If your car is a manual, they’re called “adjusting” parts.

5) Refitting fluid lines and connectors

“Fluid lines and connectors” are the pipes (and other connections) that transport the different fluids used in your automatic transmission. If these have been damaged by wear or rust, they’ll need to be replaced before you can drive away.

6) Re-commissioning

Before starting your car after the transmission repair, a mechanic will have to “re-commission” it. They will conduct a series of checks to ensure everything is working. These checks include sending a test drive and ensuring the gearbox responds to its commands.

7) First drive

Once your car has been fully re-commissioned, the first thing to do is a test drive to see that the problem has been resolved. 

8) Parts tracking

The auto repair shop will keep records of all parts used with detailed descriptions and manufacturing details. This includes parts numbers, part codes, and even the serial numbers of components that have not yet been installed. These records are invaluable when returning your car after the repair if there are further problems.

A professional mechanic will be able to diagnose and repair the issue quickly without causing any further damage. If your transmission has been damaged and needs repair or a total replacement, bring your car to Michigan Auto & Tire in Woodbridge today!
