Where does antifreeze go in automatic transmission fluid?

by Chris Weis. It may seem like a rather remote possibility, but engine coolant, or anti-freeze can get into automatic transmission fluid. The temperature of transmission fluid is regulated inside the engine cooling system. The fluid passes through a small tank inside the engine’s radiator.

What should the temp of an Allison Transmission be?

How hot should your Allison transmission run? If you own a 2001-2004.5 LB7 Duramax your normal operating temperatures will run around 160-180 degrees. These transmissions will warm up when towing or driving in the summer months. 200-225 is very common when the ambient air temp is 80-100 degrees and your transmission is under an increased load.

What to do if your Allison Transmission goes into limp mode?

Unfortunately, a driver can’t reverse limp mode. If you find yourself stuck in third gear with this model of transmission, it’s probably time to have it rebuilt. Pro Tip: Keep your Allison transmission well-maintained to avoid accidentally triggering limp mode. This will also improve your vehicle’s overall functionality!

What should the transmission temp be in a Duramax?

If you own a 2001-2004.5 LB7 Duramax your normal operating temperatures will run around 160-180 degrees. These transmissions will warm up when towing or driving in the summer months. 200-225 is very common when the ambient air temp is 80-100 degrees and your transmission is under an increased load.

What kind of transmission does a Duramax pickup have?

Nearly all Duramax powered pickup trucks were equipped with the Allison 1000 automatic transmission, with the five-speed version running from 2001 to 2005, and the six-speed starting in 2006 and running until 2019.

What’s the problem with the Allison Transmission 1000?

What to do if transmission cooler is not serviceable?

The transmission cooler tank in the radiator is not serviceable in modern applications, and the radiator and tank are replaced as one unit. The engine cooling system may be completely restored by a thorough flushing and the installation of new hoses and coolant along with the new radiator.

What should the temperature of a transmission line be?

The fluid cycles in and out to maintain a normal temperature range. With good quality fluid and functioning lines your transmission will ideally be running at around 175 degrees.

What should I do if my transmission cooling line is leaking?

Sites like Autozone have a wide variety of transmission cooling line assemblies you can buy. Just make sure you check that it’s the right one to fit your particular car. Prices average anywhere from $15 to $50. In a pinch you can also use a sealant on the line if it’s leaking at a connector.

Where does the ATF go in a transmission heater?

ATF from the trans enters the heater via the lower tube, is simultaneously heated by engine coolant, and also is routed out to the ATF cooler. The TBV lets heated ATF flow back into the trans via the upper tube, and blocks the cooled ATF from flowing back into the transmission.

What should the transmission temp be in a hot car?

Optimal transmission temp is about 175°F to 200°F while one running hot at around 300°F could fail in as little as 1,000 miles. That is why it is important that any car owner hoping to keep their car’s transmission healthy will need dependable, leak-tight automatic transmission cooler lines to carry that fluid to and from the cooler.

Which is the best transmission heater for fluid?

You can subtract 60 from the number your running at in temperature, and that in effect is how the fluid is “behaving’. Even if you are using PAO, subtract only 30f to be safe, and see you are way under 180F. And for the record it seams like the 8 speed is about the best transmission for fluid I think I’ve seen.

What are the different types of transmission cooler lines?

Types of Transmission Cooler Lines 1 Metal Transmission Cooler Lines. Metal transmission cooler lines are typically pre-bent with fittings that are held on by a flare at each end of the line. 2 Rubber Transmission Lines. 3 Nylon Braided Transmission Cooler Lines. 4 Steel braided Transmission Cooler Lines. 5 Hose Clamps.

What happens if engine coolant mixes with transmission fluid?

Engine coolant surrounds the tank to help keep the fluid inside at a constant temperature. 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,…

How is the temperature of transmission fluid maintained?

The temperature of transmission fluid is regulated inside the engine cooling system. The fluid passes through a small tank inside the engine’s radiator. Engine coolant surrounds the tank to help keep the fluid inside at a constant temperature.

What to do when coolant leaks into transmission?

Before fitting the new radiator, the whole system will need to be flushed. This is also a job for a pro shop, specialized kit and a de-greasing agents are required. The system will need to filled with fresh coolant and system bled. What Happens When Coolant Leaks Into Transmission?

Where is the coolant reservoir on a Ford?

Open the hood and locate the engine coolant reservoir. It is often a translucent white color, and has hose (s) connecting it to the radiator. The reservoir has a fill range marked on the side. If your engine is cold, the coolant level should be up to the cold fill line.
