Here’s what happens: During normal driving, the transmission gets hot just like the engine. To cool the transmission, the fluid is directed through a cooler that sits inside the radiator. When the engine cooling system is working properly, the engine coolant passes over the transmission cooler in the radiator.
How do you know if your transmission is leaking coolant?
Diagnosing a leaky transmission is fairly simple. The location of the leak alone should make it obvious, as long as you know where your vehicle’s transmission is located. The fluid itself is also quite distinct — it’s usually red and leaves a reddish stain. It also has a lower viscosity than engine oil.
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.
Can low coolant cause transmission overheating?
The transmission changes gears using principles of hydraulic power, which causes a burning odor. It takes much longer for a transmission to respond to low fluid levels. A transmission is much more likely to overheat if the fluid levels drop too low.
What are signs of transmission problems?
What Are the Transmission Failure Symptoms?
- Refusal to Switch Gears. If your vehicle refuses or struggles to change gears, you are more than likely facing a problem with your transmission system. …

What causes transmission overheating?
An overheating transmission usually means there is already some sort of internal damage or a transmission fluid issue, such as a leak, low fluid level or just old/dirty fluid running through the system. It can also happen with too much transmission fluid, which causes excess pressure within the transmission.
How do you fix an overheating transmission?
What to do when your transmission is overheating:
- Stop driving immediately and let your transmission cool down.
- Make a note of what you were doing, where you are, what’s happening (noises, etc.)
- After cooling down, start back up & gingerly continue on your way.
How do I cool down my transmission?
Allowing the car to idle in neutral, while sitting at red lights, in congested traffic or at rail road tracks, reduces the strain on the transmission, allowing the transmission to cool.
