Which way does transmission fluid flow through radiator?

The principle is the cold water absorbs the heat from the engine, the hot water being lighter moves up, therefore water is introduced from the bottom. The transmission fluid is piped through the radiator to cool it.

Does it matter which transmission line goes where on radiator?

Generally the higher line on the radiator has fluid going INTO the transmission and the lower one goes back to the transmission, so the higher line has fluid coming out of it and the lower line sucks it back into the transmission.

Are transmission cooler lines directional?

Can Transmission Fluid Flow Through Either Direction on a Transmission Cooler. Helpful Expert Reply: … The cooler can have fluid flow in either direction through it.

Do transmission lines run through the radiator?

How Car Transmission Lines Work. Car transmission lines connect your vehicle’s transmission to the vehicle’s radiator. Also known as transmission cooling lines, they are typically made of metal or composite aluminium and rubber hoses because they can handle the flow of hot transmission fluid.

How do transmission cooler lines connect to radiator?

Transmission coolers do not attach to the radiator. They attach in-line with the transmission fluid return line. It is common for an OEM transmission cooler to be built into the radiator tank to be cooled by the coolant in the radiator.

What happens if you hook up transmission cooler lines backwards?

If you had it reversed, the pump would be trying topush fluid through the bottom of the cooler, up through the cooler, out the top into the bottom of the rad, and up through the rad to the top. More weight to push.

Can I use rubber hose for transmission cooling lines?

You can use rubber hose, but make sure it’s transmission cooler line rated. The pressure is quite low (12-15 psi). Double clamp it or use FI type clamps instead of the worm-drive style.

Should transmission cooler be before or after radiator?

Answer: We recommend installing the auxiliary cooler after the radiator to return the coolest fluid directly to the transmission. Installing the cooler before the radiator will still provide additional cooling and may be necessary in some difficult-to-access applications.

Should I bypass radiator transmission cooler?

Bypassing your radiator transmission cooler would likely cause the fluid in your transmission to over heat causing premature transmission failure. If you are going to bypass it and hook up a better cooler … maybe but if you are eliminating a cooler al together that’s a terrible idea.

Why do transmission lines run through the radiator?

The principle is the cold water absorbs the heat from the engine, the hot water being lighter moves up, therefore water is introduced from the bottom. The transmission fluid is piped through the radiator to cool it. The hot fluid is one of the main reasons for automatic transmission failure.

Is the transmission cooler in the radiator?

The cooler for the automatic transmissions are placed inside the radiator, the reason behind this is the antifreeze provides the perfect environment. It warms the transmission up with it’s cold and keeps it from getting too hot in extreme heat.

Can you use a radiator as a transmission cooler?

In terms of transmission operating temperatures keeping the fluid 200 degrees or less is preferred for long life — for every 20-degree increase in temperature above that, the life of the fluid is cut in half. … When it comes to cooling a transmission we never use radiators with built-in transmission coolers.

What two lines connect transmission to the radiator?

The hoses traveling from the transmission to the radiator are called transmission cooler lines. They channel hot transmission fluid to the radiator, where it is cooled, then return it back to the transmission. They typically resemble brake lines and are made of metal.

How does transmission fluid flow?

ATF is pressurized by the transmission oil pump that is driven by the engine. The pressurized fluid flows through the transmission to engage and disengage the clutches and bands. A valve body, usually located in the bottom of the transmission, controls the fluid flow to the clutches and bands.
