Why is the transmission cooler leaking at the radiator?
A small type of radiator, the transmission cooler is full of hot ATF or Automatic Transmission Fluid. To enable cooling, the ATF is pumped from the transmission to the car’s front. As soon as the transmission cooler line in your car is starting to leak, you need to do initial stages to avoid risky situations in the long run.
Why does my GMC Sierra not have a transmission cooler?
One of the common issues with transmission cooling on the 14+ Sierras and Silverados is the bypass valve within the factory transmission line. This valve is designed to prevent complete fluid flow until the trans temps reach 190F+.
Where is the leak on the Trans cooler line?
The coupling where the rubber hose is crimped is leaking, it’s the one right above the orange rag. You do not have the required permissions to view the files attached to this post.
Can a transmission cooler keep Trans temps lower?
It is much easier to keep trans temps lower in older trucks due to their simple transmission cooler line setup. For newer models with a 6L80 or 6L90 however (2014+), the transmission cooler lines utilize a built in thermostat that remains closed and does not flow to the cooler until the fluid reaches 190 degrees.
Can a transmission cooler leak at the radiator?
Depending on the transmission cooling system routing, it is not too uncommon to get a transmission cooler line leak at the radiator if the lines are starting to rust. When in good condition, transmission fluid is a very bright red, so it is very easy to notice on most surfaces.
One of the common issues with transmission cooling on the 14+ Sierras and Silverados is the bypass valve within the factory transmission line. This valve is designed to prevent complete fluid flow until the trans temps reach 190F+.
What are the symptoms of a transmission cooler failure?
1. Transmission Line Leak One of the most obvious transmission cooler failure or blown transmission line symptoms is a leak. When a line leaks, there will be transmission fluid on the ground near where the leak is coming from.
What kind of transmission cooler do I need for a Chevy Silverado?
For a full size pickup truck is it typically best to get a larger cooler that has a large cooling surface with a higher GVWR, and either a stacked plate or plate and fin construction. With all these things in mind, our choices for the best transmission coolers for a Chevy Silverado or GMC Sierra include:
What happens when coolant leaks in a Nissan?
Widespread transmission failure in 2005-2010 Nissan SUVs and trucks can be traced to coolant leaks from busted radiators. The leaked coolant mixes with transmission fluid creating a toxic mixture, known as the “strawberry milkshake of death”, that destroys everything around it.
What happens when a radiator in an automatic transmission ruptures?
Ruptured radiator cooler tanks are forcing coolant into the five-speed automatic transmission through the cooler lines. Not only does the radiator stop cooling the transmission, but the resulting slurry of coolant and transmission fluid eats valves, erodes seals and speeds up corrosion.
What happens when radiator coolant goes bad in car?
Not only does the radiator stop cooling the transmission, but the resulting slurry of coolant and transmission fluid eats valves, erodes seals and speeds up corrosion. The liquid is known as the strawberry milkshake of death (SMOD) and it’s not because it tastes good (please don’t taste it). Once you’ve got SMOD you’re SOL, FWIW.
How can I tell if my transmission cooling line is leaking?
There are a few ways to tell if your transmission cooler line is leaking just from inspecting it on your own before taking it to see a mechanic. The most obvious sign of a transmission cooling line leak is the presence of transmission fluid.
What causes a leak in the transmission pan?
The transmission pan is fairly easy to spot when you look at the bottom of your vehicle. Pan gaskets are designed to seal the pan so that it does not leak. If they do not have a perfect dry seal, transmission fluid can leak from this area. This can happen due to normal wear and tear.
