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.
Does a transmission cooler really help?
As long as it is properly installed, a transmission cooler will not affect a factory transmission. It is a flow-through device and does not affect any internal components of the transmission. A transmission cooler will just help to prolong the life of the transmission by keeping the fluid cooler.
Does transmission cooler use antifreeze?
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.
How do I know if my transmission cooler is working?
5 Symptoms of Cooling System Trouble
- Rising engine temp gauge. Most cars have a dashboard temperature gauge that lets the driver know the operating temperature of the engine. …
- White steam. …
- Low coolant level. …
- White exhaust smoke. …
- Visible coolant leaks.
How does a transmission cooler in a radiator work?
The way a transmission cooler works is that heated fluid is sent from the transmission to the radiator and then to the cooler, and air moving over the fins of the cooler help to lower the fluid’s temperature, and is ultimately sent back to the transmission in a continuous loop.
Do all vehicles have transmission coolers?
While all automatic transmission equipped vehicles have a transmission cooler in their radiator, this might sometimes not be enough to properly cool your transmission fluid.
How do I keep my transmission cool?
Installing an external cooler can prove greatly effective in cooling your transmission and keeping it at a regulated temperature, which helps to prevent damage. External coolers also help to reduce friction to the transmission, which is another common cause of damage.
Can I run two transmission coolers together?
Not many pros. In series is fine. One in front of the other will be a not be much more effective than just one. One reason is the air that goes thru the front cooler gets heated up and is less effective as it goes thru the rear.
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 .
What makes transmission overheat?
Low fluid levels or old transmission fluid causes friction between the parts and causes overheating. Fluid problems are the most common reason for transmissions overheating.
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.
Do transmission lines run through the radiator?
Car transmission lines connect your vehicle’s transmission to the vehicle’s radiator. … Your car’s transmission lines are essential to preventing the transmission from overheating by carrying hot fluid away from the transmission until it is cooled and subsequently pumped back into the transmission.
Can the radiator cause transmission problems?
When the engine and radiator do not receive the right flow of coolant, then it it can cause radiator problems. … If a faulty radiator is not repaired, then it could also cause damage to the transmission if the transmission fluid is cooled using the radiator.
Does transmission fluid run through the radiator?
All transmissions have a cooling line that runs to the radiator. A separate fluid passage circulates the transmission fluid through a portion of the radiator to cool the fluid.
