Engine transmissions

Standard Transmissions, Automatic Transmissions

As our name implies, transmissions are our core focus. Granted, your engine provides the power your car needs to run, but without a functioning transmission, your car won’t move when you step on the gas.

Leaking transmission fluid is a common sign your transmission needs attention. This fluid is similar to engine oil, except for it’s red in color, whereas engine oil typically ranges from dark brown to black. Your service engine light can frequently indicate a problem with your transmission. Whining or buzzing sounds coming from your vehicle may also be a sign that your transmission should be checked. Other common indicators include jarring of the vehicle when shifting or hesitation and slipping when moving from one gear to another.

If you ignore these signs, you risk causing damage to your engine and other powertrain components should your transmission fail. Please bring your car to us before this happens. We will perform all basic transmission inspections “for free” and let you know what needs to be done to correct the issue. If you have a special computerized transmission or require advanced diagnostics, we have the advanced diagnostic equipment that’s necessary to identify any problem.

Stu's Long Beach Exhaust Specialists


Stu's has a special deal with the manufacturer to get their parts at up to 35% below factory blue sheet pricing. This means they can pass the savings along to their customers. There is a pipe bender on-site and they can create any setup needed whether it's for your daily driver, classic car or high performance race car. 

Standard Clutches

The clutch in your vehicle regulates the transfer of power from your engine to your transmission. Because of the way the clutch is designed to function and the amount of stress it sustains during the operation of your vehicle, parts of it wear out over time. A worn clutch can significantly degrade the performance of your car, so it’s important to get it serviced when required.


A differential allows the wheels of your car to rotate at different speeds, typically by using a set of gears. Without a functioning differential, your car would not be able to turn without forcing some of the tires to lose traction. Differentials are also frequently used to increase the safety of your vehicle in slippery road conditions. At Stu’s AE Transmission, differentials are one of our specialties, so if you have a problem with yours, we can fix it for you.

ECU Re-Programming

Vehicle Computer Flashing 101! Most cars on the road today have an onboard computer. This computer is responsible for monitoring a variety of sensors, such as the engine temperature sensor and oxygen sensor. Onboard vehicle computers are also responsible for alerting the driver when something goes wrong by flicking on the notorious “check engine” light. Vehicle computer flashing might not be the most common type of maintenance, but it is an easy and practical way to make sure you are getting the most out of your vehicle. More Info...
