Some Causes of Transmission Overheating

Heavy towing - Lots of heavy towing causes your transmission to overheat more easily, which is why maintenance is required sooner. The extra weight that the loads add to your car means your transmission has to work harder than normal just to get going.

Lots of stop and go traffic – Living in the city means there’s a lot of traffic, and constantly stepping on the brakes and accelerator causes your transmission to work harder than normal.

Hot climate - A hot climate contributes to an overheating transmission by raising the fluid temperature. This causes the ATF to wear out more quickly.

Ah I see when the shoe turns on the other foot you cry fowl, you're a juvenile You called me Mr. Sound and I returned the favor.
I debate based on facts and I don't do emotions.
No need for any obtuse idiomatics, just simply state facts.
What do marines have to do with this debate I ask again?

Kashif:
I had chosen to ignore you but just can't overlook the level of your childishness. Grow up and try avoiding bickering. Always looking for an axe to grind.

Emotions ke? A huge joke! Growing old without growing up is not cool. Show some level of maturity and stop showing yourself; nobody cares.

The Ford PowerShift is a six-speed dual clutch semi-automatic gearbox produced by the Ford Motor Company The Ford PowerShift gearboxes are built by Getrag Ford Transmissions, a joint-venture with Getrag PowerShift improves fuel efficiency by as much as 10 percent when compared to a conventional automatic transmission.

The operation of a dual clutch transmission is analogous to two traditional manual transmissions, each with its own clutch, operating in parallel and alternating shifts. The Ford unit is a six-speed with one clutch acting on first, third and fifth gear, and the other used for second, fourth and sixth gear. As first gear is engaged, the 2-4-6 clutch is disengaged and the second gear cogs are engaged. At the appropriate time, the 1-3-5 clutch is disengaged and the 2-4-6 clutch is engaged. While in second gear, the other side shifts from first to third. The process is repeated with quick smooth shifts and none of the efficiency loss normally associated with torque converters.

The PowerShift gearbox is a joint development between Ford, Getrag and Luk and was first introduced in Europe. Both Volvo and Ford use wet clutches and hydraulic actuation. However, the new PowerShift gearbox used in the Ford Fiesta and Ford Focus uses dry clutches and electric motor/solenoid actuation.

The Ford Powershift automatic transmission uses two 3-speed gearboxes connected via a pair of clutches. When drive is selected, transmission #1 engages 1st gear and transmission #2 selects 2nd. Clutch #1 engages and the car pulls away in first. When it’s time to change gear, it uses clutch #2 to swap transmission, with #1 immediately pre-selecting 3rd etc

The display observed by the customer is likely in line with the built-in strategy on the vehicle ECU and therefore should be normal based on the design of the transmission and the operating condition of the vehicle(heavy traffic situation) during the display.

For avoidance of doubt please see an excerpt of the transmission strategy below. We further need to educate our customers using vehicles with this transmission assembly(Focus). I believe this will improve their knowledge and understanding of the vehicle and reduce their fears.

Hot mode

The temperature of the clutch is calculated via a model in the TCM.

The following variables are incorporated in the calculation:

Engine torque
Rotational speed signals from the ISS A, ISS B, OSS and the engine speed
Calculated torque transfer of the clutch

The Hot Mode function is used to prevent the clutch from being damaged as a result of excessively high temperatures. When hot mode is active, the clutch is engaged more quickly and the engine torque is reduced.

At a calculated clutch temperature at which the clutch lining would suffer heat damage, the following message is displayed on the message center:

Transmission hot - stop the vehicle or accelerate
Transmission hot - wait
Transmission hot - wait 10 minutes.

Once the clutch has cooled down, the message "Transmission ready for operation" is displayed on the multi-function display of the instrument cluster.

At a calculated clutch temperature of more than 300 °C (572 °F) the clutches are disengaged.

To summarize all transmissions with torque convertors do get hot and can cause the fluid in them to blacken (burn) and it is only a few that will give you a protection warning usually switching off the drive. These Ford dry dual clutches are similar to the normal manual transmissions and it is a known fact that the clutch will be affected if any manual transmission is held in gear for too long. The Edge and the Explorer gearboxes have a normal fluid torque convertor.

Page 93 of the Ford Focus Owners Manual gives a clear indication of care to be taken. Picture attached.

A 5 month old car should not need a transmission service.

OP be careful about an advice to service your transmission unless you do it at the selling dealer for protection.

How far on the legal front?

Mrcharming:
@ CityNG . He that does not read is not different from he who cannot read (an illiterate). If the op had read the car manual, he would have been acquainted with the workings of the vehicle and he wouldn't have exposed his ignorance about the car. This is the 21st century, where everything is dependent on knowledge, I don't see why we should continue to promote mental indolence. You should read all manuals, whether it is the one that came with your phone, laptop, blender, car or any other appliances. It was produced for a reason, it is not just a mere paper attachment.

Onyx79,

No matter how you don't want to hear it, the dealership is not far from the truth. You are using the transmission wrongly.

Our problem is we always think we know how to drive this things and use them, hence, no one bothers to get or read their owners Owners manual after acquisition. Its likely it was stated clearly in that manual what the dealership told you.

Most owners manual I have come across will tell you not to leave Auto tranny in Drive in traffic jam for certain amount of time. But we don't do adhere to all these instructions because we sabi everything. Heat is a main killer of Auto transmission, ford or Honda, it leaves no mercy.

The early EFI systems would not protect the engine or the system when something big fails, hence, people continue to drive such cars in those conditions until it kills the engine, transmissions or cause major breakdown or repair. But on recent EFI vehicles, they have been programmed to go into limp home mode to protect the vehicle when certain sensitive EFI or transmission systems fail and force you to fix the issue. Likewise, early EFI had no system check on catalytic converters, hence, people continue to pollute the environment even when their catalytic converters fail. But with Euro IV & V emission systems on Peugeots, once the monitoring sensor of the caty fails, the car will automatically becomes sluggish on acceleration. To force you to replace the failed downstream sensor that monitors the caty, so that it continue to monitor and warn you when the caty is in bad shape, to prevent polluting the environment. If I would understand what you said, Ford introduced a system to protect the Ford Auto tranny from breaking down, when owners refuse to drive their cars properly. "Transmission overheating" could simply means a warning to reduce stress on transmission when not in use. Do you actually know what goes on in transmission when you leave it on drive and hold the car with brake? Why do you think peoples Auto trannys fail even when they religiously renew their transmissions ATF with recommended fluid?

Open, read and study the owners manual the car came with a,d understand how to operate the car, if you wish long lifespan for the car.

You could be right, but the dealership was not wrong either, as far reason they gave you was concerned.

I need your assistance, dear brother. I'm facing a problem with my Ford Focus 2012, which is just under 5 months old. It began displaying the same warning, and I'm struggling to comprehend it fully. The complication is compounded by the fact that I purchased it through auctionexport.com in the USA, and I'm currently in Nigeria, far from any dealership support.

On occasion, when the car indicates an overheating issue with the message "Overheat, wait 10 minutes," I follow the instructions diligently. However, there are times when I disregard the warning and continue driving, especially when stuck in traffic.

About 1-2 months after the first overheating warning, I drove to a mall in Abuja without any such indication. However, upon returning to my car and starting it after a brief 10-minute stop, the transmission suddenly malfunctioned, causing significant damage to both the gear and the body of the gear.

I had to take the car to a mechanic and had to purchase a direct Belgium (second-hand) transmission to replace the damaged one. This endeavor cost me a substantial amount, including the cost of the transmission, repairs, and installation. Unfortunately, less than a month after installing the Belgium (second-hand) transmission, the same issue resurfaced. As I speak to you now, the transmission is not functioning properly. It struggles to engage gears, and even when it does, it fails to move smoothly and doesn't shift correctly. The transmission specialist suggests that the issue is with the Transmission Control Module (TCM) and recommends replacing it to resolve the problem. Due to these recurring issues, I've had to park the vehicle to prevent any further damage or accidents.

Some individuals have advised me to convert the car to a manual transmission. I'm feeling utterly perplexed and distressed by this situation, as I have yet to fully enjoy my car. I'm reaching out to you for urgent assistance. Based on your knowledge and expertise, what steps should I take to restore the functionality of my car?

Your help is greatly appreciated, and I value your insights. Please, I implore you, to guide me on the best course of action to rectify this issue and enjoy my vehicle once again.

I'm in desperate need of assistance. Thank you!
A lot factors could responsible for the overheating issue , check ur radiator and AC fans properly.faulty oil sensors inside automatic transmission too could cause it, oil sensor wiring from control module could also cause it. Tell ur auto electrician to check the wiring from gear box to the engine or transmission control unit connector for short circuit. Don't convert it to manual gear.
