Hello there, I was wondering if I would need to add a manual transmission if I add a twin turbo to my automatic car.
2005 Hummer H2 Sut with 92000 miles with an automatic transmission wondering if I can put a twin turbo in it and keep the automatic transmission or would I need to put a manual?
My car has 92000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
I recommend keeping your transmission in your vehicle that it is designed for. If you plan on putting in a Twin Turbo setup, then the transmission will hold up to the changes. Automatic transmissions are designed to take more abuse than a manual transmission for they have more gear to gear contact and that they can adjust clutch pressure at a greater force. You may need to build your transmission with a heavier clutch pack material, but other than that, your automatic transmission will working just fine. If you need further assistance with determining if your transmission will hold up to a Twin Turbo Engine, then seek out a professional, such as one from Your Mechanic, to help you.

Yes, there is absolutely no difference between an automatic and manual car in regards to forced induction. The transmission shouldn`t get in the way of adding a turbocharger.
A DCT works by using two clutches instead of one, and both are computer controlled, so there`s no need for a clutch pedal. The dual clutch transmission operates via several in-built computers. These computers eliminate the need for the driver to manually change gears and the entire process is automated.
For three model years in America, you could buy a BMW 535xiT, a wagon with all-wheel-drive, a twin-turbo straight six making 300 HP, and paired with a manual transmission.
Supercharger or turbocharger
A turbocharger works with the exhaust system and can potentially give you gains of 70-150 horsepower. A supercharger is connected directly to the engine intake and could provide an extra 50-100 horsepower.
You can turbocharge almost any car, as long as the new equipment you need to add can fit on (and in) your vehicle. Turbocharging – when done correctly – can significantly increase the amount of horsepower your engine has.
What is a CVT like in the city? A CVT transmission is possibly the best to drive in the city. Because it has an infinite amount of gear ratios, the TCU of a CVT keeps the engine in its sweet spot making this transmission one of the most efficient. With that, as there are no physical gears to change, these are smooth.
Dual-Clutch Transmission Benefits
DCTs tend to provide better fuel economy than automatic transmissions and smoother performance than manual transmissions and AMTs. Because they shift smoothly and with a high-degree of precision, they`ve often been preferred in the arena of performance driving.
It`s a dying breed. But don`t have your left foot removed just yet: there are still new cars available in the United States with a manual gearbox. (A handful of SUVs come with them, too, but we covered those in a separate list.) If you`re after a row-it-yourself driving experience, one of these cars should do the job.
When it comes to finding car models that offer a manual transmission, Toyota has many options under its wing. Numerous Toyota models and trims with a manual transmission come at affordable prices. Toyota also offers manual transmissions in two types – 6-speed and 5-speed.
In general, adding a turbocharger to an engine will add anywhere from 40 hp to 300 hp, but in some cases, much more.
If you`re looking to maximise the power and performance of your vehicle, then changing your stock turbocharger for a bigger or better model can be an effective part of the process.
A twin-turbocharger works by using two turbochargers of the same size to force air into the engine`s cylinders to add extra horsepower. The exhaust gases are recycled, split between the two turbos, and usually combined in a shared inlet before entering cylinders.
The longer you drive your car with a blown turbo, the more damage the engine will have and therefore the more costly it will be to repair.
Torque converter transmissions offer big torque at low revs, but are generally less efficient than single and dual-clutch transmissions. Complicated dual-clutch transmissions use two sets of gears to allow for quick, almost seamless, changes between gears.
Automatic vs. manual: which is faster? It`s a common myth that manual cars are faster than automatic ones, but that isn`t the case. High-speed vehicles are available in both transmission types, and the transmission isn`t the most important factor in determining top speed.
Manual gearboxes are better at transferring power from engine to wheels, and offer faster acceleration. They are also simpler than automatics and so are less prone to failure.
Continuously Variable Transmission (CVT)
This allows continuous acceleration and maximum fuel efficiency.
But, it`s not just a problem for manual transmission, automatic transmissions also experience clutch failure.
As great as dual-clutch transmissions are, like every type of transmission type, they do have their drawbacks. One of the most common complaints about a DCT is that it tends to jerk and lurch when driven at lower speeds, such as in a parking lot or when the car is in reverse.
Generally, a dual-clutch transmission shifts faster than a standard hydraulic automatic transmission with a torque converter or a single-clutch automated manual transmission.
With proper driving, use, and maintenance of the manual transmission`s components, you can expect it to last over 120,000 miles. By keeping an eye out for transmission oil leaks and operating the clutch and gears correctly, you can expect a long life out of your transmission.
Many Europeans argue that driving a geared vehicle is less boring than driving an automatic. The acceleration of a manual car is far better than an automatic one. Most automotive enthusiasts prefer owning and driving a stick shift as it gives them the rev and speeds they pine for.
While many people in North America drive automatic vehicles, most Europeans drive vehicles with manual transmissions. Europe`s continuous use of manual transmissions can be attributed to various factors of the continent`s history and present-day circumstances.

There is automatic transmission fluid in a manual transmission. Is it okay to leave or do I need manual transmission fluid?
ANSWER : This would depend on what the manufacturer recommends. Many manual transmissions do take automatic transmission fluid. If your transmission has ATF in it, it is very likely that it is supposed to have that in there. If not, it is likely that the transmission would not function properly with the wrong fluid. Many manual transmissions will also take engine oil as a lubricant. The best way to know for sure is to check your owner’s manual or call your local General Motors dealership to inquire.
2013 Ford Focus Transmission Issue. Is it worth keeping the car?
ANSWER : Hi There,
This is a known issue in this generation Ford Focus and some Fiestas with the "Power Shift" transmission and there have been numerous recalls and lawsuits. Although, it is would be difficult to determine how much longer your transmission will last given the fact that you have many new parts, I would not recommend junking the car as it may still provide some valuable life left for you. I would recommend taking it to the dealer to see if these parts may be covered under the recall.

How much to replace an automatic transmission to a manual
ANSWER : The PCM and TCM that you presently have are incompatible with a manual transmission. The PCM hardware and some engine controls, particularly relating to idle speed and electronic "dashpot", would be different too. The only way you could reliably do such a swap is if you changed out the vehicle’s electrical system, include the wiring harness to the transmission and engine, and even that wouldn’t be a guarantee of success if your vehicle also has a body control module (i.e., that would have to be changed out as well). Your only practical option is to have the existing transmission re-built or install a re-manufactured one. Even going that route, you have to be extremely careful and vigilant that you get an EXACT replacement, in every respect, because even minor year to year differences in electronic controls could render the unit unusable. In some locales, certified Mechanics from YourMechanic will perform engine and transmission replacements, so please inquire if you simply want to repair what you have. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
Everytime I put car into gear it shuts off the car but idles fine
ANSWER : This sounds like a faulty speed sensor problem. Most cars have two speed sensors (one monitors input shaft and one monitors output shaft) which tell the computer what the gear ratio is of the transmission while in use. If either of these are not working properly, they will cause the computer to shut the car off for safety reasons. I would suggest having an expert from YourMechanic come to your home to diagnose your stalling issuee and help you repair it.
Turbo VS. Non-Turbo Valve Cover Gasket
ANSWER : Hi there. Looks like the gaskets are the same for the turbo and non turbo engines. I recommend asking the local parts store for to see a valve cover gasket for the non turbo engine and a gasket for a turbo engine and compare the two gaskets. If the gaskets are the same material and have the same design, the go for the valve cover gasket that will fit your budget. If you need further assistance with the valve cover gasket, then seek out a professional, such as one from Your Mechanic, to help you.
I just got a new transmission put in my car and it drives and reverse but won’t go up hill.
ANSWER : This may be a sign of a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car’s computer activates a transmission solenoid, which directs transmission fluid into the valve body to engage the correct gear. When this is faulty or not working properly, this can cause a delay in gear shifting or in some cases cause the car to not shift at all. I would recommend having an expert from YourMechanic come to your location to take the car for a test drive to more specifically determine the cause for this.
Gear shift slips over to Manual Transmission without touching. I have to hold it to keep it in Automatic.
ANSWER : Hi there. All automatic transmissions require transmission fluid for them to work. In your engine compartment by the right side next to the radiator area, there is a box in front of the air filter housing. Remove that box and below the air filter housing you will see the dipstick to the transmission. For the transmission not staying in automatic mode and conveying over to the manual mode only, the shifter has either broke inside or the circuitry has a short in the shifter housing. I recommend replacing the shifter assembly with a new one. If you need further assistance with your shifter not selecting automatic mode, then seek out a professional, such as one from Your Mechanic, to help you.
