What runs through transmission cooler lines?

Fluid heated by the transmission, engine, or power steering pump flows to the cooler. The air moving over the fins of the cooler cools the fluid, which is then routed back to the transmission, engine or power steering pump in a continuous loop through the return line.

What fluid runs through transmission cooler lines?

The most obvious sign of a transmission cooling line leak is the presence of transmission fluid. Look for red fluid when you move your car or if you’re under the hood, look around for that same red fluid on any hoses are gaskets.

What flows through a transmission cooler?

How Does a Transmission Cooler Work? Fluid heated by the transmission, engine, or power steering pump flows to the cooler. Air flowing over the fins of the cooler carries away heat and cools the fluid flowing within the fins. The cooled fluid is routed back through the transmission via the return line.

What happens if transmission cooler line breaks?

When a transmission oil cooler hose fails it can cause the transmission to overheat. This can be due to low fluid level from a leak or preventing flow. In either case if the transmission overheats it can stop working entirely and this condition may be permanent.

Can you repair transmission cooler lines?

Like all parts of an engine, transmission cooling lines can wear out. If they break or develop a leak, you will lose transmission fluid, leaving your car vulnerable. Thankfully this is a fairly simple fix, and most transmission line repairs cost between $100 and $500 dollars.

Can a transmission cooler be too big?

Too big could be a concern if mounted in the front of the rad creating a loss of air flow to keep the engine cooled . Years ago , GM released a TSB about overcooling the transmission in cold climates .

Can I bypass the radiator transmission cooler?

Re: Auxiliary Trans Cooler, Can I Completely Bypass Radiator



The fluid is generally run through the radiator to pre-cool it before going through the aux. cooler. So as long as the cooler you are adding is capable of the work then there should be no problem with it.

How long do transmission lines last?

Underground high-voltage transmission lines have a life expectancy of 40+ years, while overhead lines have a life expectancy of more than 80 years.

Can you over cool a transmission?

Can you over cool the transmission fluid? Answer: Transmissions are not highly sensitive to cool operating temperatures. However, in sub-freezing (20-30°F) weather conditions, transmission fluid can actually gel up in an external cooler and cease to flow, causing damage.

What happens if you put antifreeze in transmission fluid?

The temperature of transmission fluid is regulated inside the engine cooling system. … Any rupture of the internal radiator tank can allow coolant to mix with, and contaminate transmission fluid. The engine coolant can also become polluted by the transmission fluid, as the pressures of either liquid vacillate.
