When you visit Gi Automotive group for a transmission, clutch or drivetrain service, our mechanics will inspect and try to replicate any issues you are experiencing with your transmission, clutch or drivetrain system before providing a path forward. Your transmission fluid will be tested to determine if you require some transmission fluid to fill your system or even a full transmission flush if we determine your transmission fluid is contaminated.

Most luxury and exotic cars do not come with a sensor to indicate how much life is left in your clutch whether it’s an automatic or manual transmission which means the only way to know for sure is to remove your transmission and inspect your clutch to see how much life is left in it. We will provide you with our recommendations and options to replace transmission or clutch, or simply flush your transmission and replace the transmission filter if needed and what it will cost to fix it with a written estimate.


Your luxury or exotic car has a transmission that mechanically transfers power from your engine and delivers it to the drivetrain and wheels.

The transmission plays a vital role in controlling your vehicle, as it is responsible for ensuring the power generated gets to where it needs to be when you need it. It’s also responsible for providing you with a smooth acceleration/deceleration through gears as you speed up or slow down. (Unless you have a manual transmission car and don’t know how to drive it very well). The transmission works to maximize the efficiency of your car’s engine so it can reduce the fuel consumption without negative effects on the driving dynamics.

When taking off from a stop, your vehicle’s transmission automatically selects lower gears to provide more torque at lower speeds to initially and smoothly move the wheels to get the car accelerating. During highway driving, the transmission uses higher ratio gears to move the vehicle at much higher speeds while keeping engine RPMs relatively low. Most transmission problems are a result of overheating. Reasons for overheating include low fluid levels, leaks, dirty fluid, or problems with the solenoid.

Did you know that an overheating automatic transmission can cause your engine to overheat?  If your transmission is not running properly with clean fluid, it is prone to excessive wear, friction, and slippage – all of which creates a lot of heat that has to be processed by an already hard working radiator cooling system. 


Manual transmissions are being engineered less and less with every new model from all manufacturers. Ferrari, Lamborghini & Mercedes do not offer manual transmissions anymore. McLaren never did. Porsche, Aston Martin and BMW still provide us enthusiasts with manual transmission models especially in their sport & performance based cars.

Instead automatic transmissions have evolved into single-clutch & dual-clutch variations to reduce weight, increase acceleration and optimize fuel economy. Today’s automatic transmission in luxury & exotic cars are technically manual transmissions controlled by your vehicles computer. Unfortunately for those of us who love engaging with our luxury or exotic cars through the uses of a manual transmission are a minority. Although automatic transmissions are now more popular, manual transmissions can be easier to understand.

The transmission is made up of gears, output shafts, and input shafts. Gears of one shaft engage the gears from the other shafts. When using a manual transmission, a gear is selected by engaging the clutch pedal and moving the shift lever into the desired gear (sequentially up or down).

When you disengage your clutch by pushing the clutch pedal, it disconnects the engine and the input shaft (that delivers engine power to the wheels) so that you can shift into the next gear.  Once you have selected your next gear, the clutch is released to re-engage engine power toward the input shaft delivering the engine power to the wheels. Automatic transmissions work in a similar manner, but you don’t have to trigger them yourself and provide less interruption in the flow of power from engine to wheels. Automatics typically don’t have clutches; instead, they have a torque converter that de-couples the gear set and engine. Even though you may not physically need to shift with an automatic transmission, it does all the work of a manual transmission for you.

Here is a list of other types of automatic or semi-automatic transmissions used in luxury & exotic cars.

Automated-Manual Transmission.

Continuously Variable Transmission (CVT)

Dual-Clutch Transmission (DCT) – Porsche, Mercedes, Audi, BMW

Sequential Manual Gearbox (SMG) – BMW

DSG (Direct Shift Gearbox) – VW

Tiptronic Transmission (old) – Porsche, Audi, Lamborghini

PDK – Porsche Double Klutch Transmission (new) – Porsche

Sportronic – Alfa Romeo

Touchtronic – Aston Martin

TouchShift / G Tronic – Mercedes Benz


Transmission fluid is a lubricant for all of the moving parts inside your transmission. In an automatic transmission, this fluid also serves as a coolant and a viscous fluid that transmits power from the engine to the transmission. There are many types of lubricants for all the different transmissions. Automatic transmissions use automatic transmission fluid.

Manual transmissions use a variety of oils or lubricants: regular motor oil, gear oil or even automatic transmission fluid in some cases. Your owner’s manual will tell you what your transmission calls for. Regardless of whether you have a manual or an automatic transmission you should definitely be changing your transmission fluid.

Manual: Most manufacturers recommend that manual transmission fluid be changed every 30,000 to 60,000 miles. Under heavy-duty use, some manufacturers suggest changing transmission fluid every 15,000 miles.

In a manual transmission, the problem is not so much the fluid degradation, but rather fluid contamination. This contamination occurs over time as the synchronizers, bearings and gears in the transmission wear out. The resulting metal particles then float around in the lubricant. And we all know that oil with microscopic particles of metal in it does not lubricate as well as clean oil. If these contaminants are not drained out, they will shorten the life of your transmission.

Automatic: Service intervals for an automatic transmission vary from every 50,000 to 100,000 miles. Changing it more often does not harm your transmission.

Because more heat is generated in an automatic transmission, automatic transmission fluid actually degrades and breaks down with use. In addition, like in a manual transmission, automatic transmission fluid & filter will also become contaminated with worn bits of the transmission. If these contaminants are not drained out, they will shorten the life of your transmission. The transmission filter helps to remove dirt and contaminants from the automatic transmission fluid. Replacing the transmission filter at the manufacturer’s recommended intervals keeps your transmission fluid clean and prevents premature wear and damage.

Most automobile manufacturers recommend changing your transmission filter every 2 years, or every 30,000 miles to ensure the contamination these filters catch are replaced with brand new clean ones to trap future contaminants as well as ensure optimal transmission fluid flow throughout your transmission for cooling. If you don’t change the transmission fluid and filter on schedule, you’ll be lubricating your transmission with metal shavings and other contaminants. This will shorten the transmission’s life. The usually results in very expensive damage to your engine and transmission. Changing your transmission fluid & filter at the correct interval suggested by your vehicle manufacturer is always a proper investment. We always recommend changing your transmission pan gasket when changing your transmission fluid and filter.


The clutch is the part of the car which connects two or more rotating shafts to enable your vehicle to move forward or backwards. In a manual transmission car, the clutch controls the connection between the shaft coming from the engine and the shafts which turn the wheels. In an automatic transmissions car, the clutch is composed of several parts, all of which come together in what’s known as a torque converter. Whenever you change your automatic transmission due to mechanical breakdown, you should also change your torque converter.


Your engine and your transmission meet at the bell housing, which contains the torque converter for automatic transmission cars. For the most part, luxury or exotic cars that have a manual transmission tend to need their clutch replaced anywhere between 25,000-50,000 miles depending on your driving style; that is how hard and how frequent you drive as well as if you do lots of “stop and go” in traffic.

In short, the drivetrain is the system that connects the axles to the transmission. This includes everything from the drive shaft, differential and constant velocity (CV) that transfers engine power to the wheels. When there is an issue with the drivetrain, it’s important to know what symptoms to look for.

Bring your car in for a visit if you’re experiencing any of the following:

  • Clicking sounds or vibrations while turning
  • Excessive vibration when speed increases
  • Grease on the tires or underside of the vehicle

Oftentimes, these symptoms point to a failure in the CV shaft assembly and may require U-joints and axle repairs, a new CV boot and other CV components.

CV Joints – Constant Velocity Joints

CV joints are essential to the safety and handling of your vehicle. Their primary function is to transmit power through a variable angle at a constant rotational speed, such as when you turn the steering wheel or when the control arm moves up and down. However, these joints are under constant strain and wear out over time. Poor road conditions and other hazards can also crack and damage CV components.

The CV assembly is more commonly known as the axle. Commonly thought of as one continuous rotating bar, axles are actually comprised of a series of universal joints and shafts engineered to optimize handling and stability while driving. If the axle of your vehicle is in poor condition, you may notice excessive vibration, especially during acceleration.

Your CV boots shields your joints from dirt and debris, keeping the joints lubricated. If you notice grease spots on the inside of your wheels, you likely have a leaky CV boot that needs replacing. Repairing the boot quickly helps prevent further damage to the CV joint itself.
