How to Protect the Automatic Transmission From Overheating: 5 Unusual (But Proven) Ways

admin 4 years ago 3 min read

Driving practises that are critical for the drivetrain in cold weather will save it in the heat especially, if you are used to driving around the city.

For which transmissions are these tips?

Including all hydrochemical gearboxes and variators, where the torque converter transfers rotation from the engine to the gearbox. The fluid in such sorts of transmissions from overheating quickly loses its properties and the capacity to protect elements from wear. Moreover, the non-metallic parts of the box themselves quickly age due to overheating.

However, the recommendations of the best car service center in Bangalore, for switching apply mostly to classic machines.

Put on the parking lot

In most cases, we do not recommend jerking the automatic transmission selector (and the variator) while stopping.

In cases of extreme heat, it is worth adhering to the “two minutes” rule. If you know that you will need to stand in traffic jams for two minutes or more, move the box to the “P” position.

What’s the matter: The primary source of heat in the car (and variator) is the torque converter. In addition, heat is primarily generated when the device is operating at maximum “slip”.

Do not turn off the “start-stop”

Most car owners do not like such systems – and rightly so. Overloads starter and battery. It is also dangerous for the motor to start forming an oil wedge in the plain bearings every time anew and scuffling the rings over the cylinders almost dry.

In extreme heat, the start-stop saves the transmission.

What’s the matter: An idle engine does not create heat and does not allow the box or variator to do the same.

Fix the first gear in a traffic jam

In extreme heat or traffic jams, when the movement, though slow, is constant, it makes sense to set the gearbox selector to the “L” position. On more modern gearboxes with the possibility of manual gear selection, set the selector to the “1” position. It is even better for the variator to set the first virtual geat in such circumstances.

What’s the matter: The gearbox will not switch to higher gears when the speed exceeds 10-15 km/ h for a few seconds. It will save the resource of valves and clutches.

Limit box switching

Another frequent city situation: the traffic jam has not yet formed, but the flow does not move faster than 40-50 km / h.

If there is heat, it makes sense to set the gearbox selector to position “2” or “3” so that the box does not try to turn on the top gear “for a second”.

What’s the matter: the extra “shuffling” of the gearbox between the gears accelerates wear, tear and makes the torque converter “slip” more, which is already hard in the heat.

Remove protection

Popular powerful protections under the engine unit and dense nets in the radiator grille and bumper holes have become almost a sign of the responsible owner.

According to the car servicing Bangalore, in the heat, remove the emergency protection of the engine compartment from the bottom if you do not ride seriously off-road. Such things make sense to put the nets only to protect the lower part of the radiators – that is, in the bumper slot. The best mesh is that which comes with a fairly coarse weave.
