【 Master Bang online 】 Answer winter shift difficulties!

The weather is getting colder recently

Many owners asked Master Bang

Why do cars have difficulty shifting gears

There is a sense of frustration

Especially those who drive manual gears

Drive to work in the morning

It's hard to shift gears when you're just driving

Especially first gear and reverse gear

The dragging phenomenon is very serious

But after a hot car or after a short distance

why

?

Master Bang told everyone

It's actually very simple

This is because of the cold weather

The car was not warmed up

Transmission fluid viscosity increases with temperature

Cause the gear to run difficult

Can not achieve perfect lubrication effect

Generally speaking

Transmission oil at low temperature

Too viscous

Just like glue to the gears

It's glued together

That's why it's so hard to get in gear

The engine gets hot when driving or behind a hot car

As the engine heats up, the heat is transferred to the gearbox

Then the heat in the gearbox goes up

And once the crankshaft starts spinning

Drive the output shaft to rotate through the clutch

It slowly increases the internal energy of the oil

Stirred by the gears and heated up

Will make the gear more smooth

therefore

If it's hard to get into gear when it's cold

It is recommended that you warm up your car before driving in winter

In addition, let's talk about the automatic model

The automatic is also due to

Transmission fluid viscosity increases

Although the oil pump began to work

But many cars also suffer from a lag in upgear

For example, the vehicle can be automatically upshifted at 2000 RPM

And the cold car just started to reach 3000 RPM

At even higher revs

You're going to be upshifting

This is where we pay attention

Because some friends will push the gas pedal very deep

Eager to rev up the engine to force an automatic upshift

Master Bang told everyone

Don't do that.

If you often let the automatic car step on the accelerator instantly when the car is cold in winter

Zoom up to 3000-4000 RPM to complete automatic upshift

There's no doubt that this will damage the automatic gearbox

Clutch plate and brake plate

Including the slide valve mechanism inside

Cause some unusual wear and tear

It will also shorten the service life of the automatic transmission

So the car automatically

It still needs the original geothermal vehicle to go again

Don't be hasty

According to the above questions, we can judge

The main reason why cars are hard to shift is

Winter temperatures are too low

Resulting in excessive lubricating oil viscosity

Hard to turn

therefore

We need to change the low temperature gear oil in winter first

Especially our friends in the north

It is necessary to consider the minimum service temperature of the gear oil

Master Bang's suggestion

If winter temperatures are particularly low in your area

75W or 75W-90 gear oil is available

To ensure fluidity at low temperatures.

Master Bang Tips

Summary of reasons for the problem of car transmission

Car temperature is low

Transmission fluid is not fully lubricated to the gear meshing surface

At this time, you need a hot car, so that the temperature is suitable

Try first gear when it's not on fire

Good hanging is no problem

It is verifiable that transmission fluid does not cause such a large amount of drag

If you change gears on the move

So there's a mismatch between speed and gear

First and reverse gears

The clutch must be able to disengage completely

Can successfully hang in

(Under the cold condition of cold car, hot car or step on the clutch to stay for 1-2 seconds)
