Can you tell me if my transmission is running too hot. 2014 Jeep Grand Cherokee
Hi! I would like to know what is normal transmission temperature for my jeep grand cherokee summit 2014 on normal driving conditions in the city or highway. I think mine gets too high, 220-235, after driving for a while on normal conditions. My dealer told me that this is completely normal that there is nothing to worry about, and that it can go as high as 270 and still be considered normal. Is this true?
My car has 30000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hi there. The transmission temperature that you are referring to is normal. The transmission on this vehicle does run slightly higher than the cooling system temperature. Most of the time it should run about 210-220. If you want to get it to run cooler then you can install a large external transmission cooler but that is not necessary. You will be fine if it continues to run the way that it is.

This indicator light is warning you that the transmission fluid`s temperature too high, which can lead to transmission failure. Transmission failures are one of a vehicle owner`s worst nightmares, as they are notoriously expensive to repair, and one of the things mostly to damage your transmission is overheating.
By using a hand held infrared thermometer.
This tool measures temperature through infrared sensor. What needs to be done is to directly point the infrared thermometer to the transmission oil pan and take the temperature reading.
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.
#1 Cause of Failure
The optimal temperature range for transmission fluid is 175 to 220 degrees. Above that, for every 20 degrees bad things happen, starting with formation of varnish at 240 degrees, followed by seals hardening, plates slipping, seals and clutches burn out, carbon is formed, and, ultimately, failure.
The maximum transmission temperature allowed before damage will occur is 302 degrees f. If your trans fluid level is low, check to see if the fluid is burnt or brown in color. If it`s brown or burnt, then you have a serious transmission problem that needs to be taken care of as soon as possible.
As mentioned briefly in the previous section, installing a transmission temperature gauge is the best way to prevent overheating within your transmission unit. This gauge enables you to carefully monitor the temperature of the transmission without interfering in the latter`s major functions.
Today we`re covering a short article on how to access transmission temperature readings through an OBD scan tool, which is a great tool to have when changing your transmission fluid.
If you`re going to be checking the transmission fluid level at home, it`s a good idea to warm up the car before you do so. If the car is checked while the engine is cold, it might give an inaccurate reading when you use the dipstick. After driving for about 10 minutes, park on an even surface and leave it running.
To keep your transmission running at a safe temperature, keep the reading between 160 and 220 degrees. Some transmissions can run a safe normal transmission temp at temperatures a little higher than that range.
We`ve researched the answer to this question. The normal operating temperature for the Jeep Cherokee ranges from 165 to 200 degrees Fahrenheit.
To keep your transmission running at a safe temperature, keep the reading between 160 and 220 degrees. Some transmissions can run a safe normal transmission temp at temperatures a little higher than that range.
Once a vehicle is in motion, it doesn`t take long for the automatic transmission fluid (ATF) to heat up. Even under normal driving conditions the ATF temperature will rise to 80 degrees C (175 F), which is the usual temperature range at which most fluids are designed to operate.
Once it`s cooled down, the fluid is sent back to the transmission to keep doing its job. And the temperature of that coolant that cools the transmission fluid? It`s about 220 degrees. It`s the same as your normal engine operating temperature, which is in the range of 210-230 degrees.

ANSWER : Hi there. The transmission temperature that you are referring to is normal. The transmission on this vehicle does run slightly higher than the cooling system temperature. Most of the time it should run about 210-220. If you want to get it to run cooler then you can install a large external transmission cooler but that is not necessary.

My car is running hot, what could be the problem?
ANSWER : There could be an issue with the cylinder head gaskets. Antifreeze can break down and become acidic if not replaced as normal maintenance. The head gasket material erodes and can cause engine compression to build up in the coolant system. This will prevent the flow of coolant which can create an overheating condition.
There is a test that can be done to check whether there is carbon monoxide in the coolant system; it involves special equipment.
I recommend having your overheating condition inspected, and perhaps have a block test performed.
Transmission flush vs fluid exchange and filter change 2012 Jeep Grand Cherokee
ANSWER : Hello – the "to change, or not to change" transmission fluid is a somewhat controversial discussion, especially in the day of claimed "lifetime lubricants". In my experience, when you plan to keep a vehicle well past 100K, it is a small but worthwhile investment to change the transmission fluid and filter in your transmission. In your case, there is a filter to change, which requires dropping the pan (exchange method). Since the exchange method leaves a large quantity of old fluid in the torque converter, you might consider draining and replacing the fluid in the pan again, after the initial filter change, refill and engine start/warm-up, to enhance the overall percentage of fluid changed. I recommend a transmission filter and fluid replacement by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, perform this service, and get you back on the road for Uber/Lyft duty quickly.
I have 2001 Jeep Grand Cherokee it runs and shut off while driving.I change the spark plug and ignition coil and and clooged exhau
ANSWER : When the engine will not start then you will need to verify if you are losing fuel pressure or losing ignition spark. You may have a bad fuel pump or crankshaft sensor. Have the computer scanned to see if you have stored codes and if there are codes for the crankshaft sensor and replace it and see if it corrects the condition.
I have a jeep Cherokee 89 and I replace the transmission lines but the new ones won’t fit into the transmission the right clips ar
ANSWER : During different years the transmission lines had different types of ends that go into the radiator. If you have just nipples on the lines, then get the proper adapters from the parts store to match them and they will screw into the radiator to attach the lines. You may need to take a picture of the line you have and get measurements of line size 5/16 OD in most cases. Get a picture of the radiator connection you have now. You may need to just change the adapters in the radiator.
I have a 2000 jeep grand Cherokee limited 4.7L V8. I was gone for a month in a half tried starting my jeep up yesterday and nothin
ANSWER : It may be normal engine electrical drain on the battery if the vehicle sat for a month or more. Once the battery is recharged fully then you can see if it will idle again. Just jumping off and only running a few minutes may not charge the battery enough to let it idle on its own. You should use a battery charger to recharge battery and retest it to see if it still stalls. You may have a bad battery and need to relearn the idle. If it still stalls then the idle control valve may be stuck closed and need to be replaced.
Car runs hot replaced the thermostat still running hot whats the problem
ANSWER : Overheating can be caused by a number of things such as low coolant levels, a faulty thermostat, a clogged radiator or a failing coolant fan switch. As you may know the coolant fan switch helps to maintain the proper coolant temperature by turning on and off at specific temperature thresholds. When this switch is not working properly, this can cause the fans to come on intermittently, all the time or sometimes not at all. When this happens you will notice a temperature spike and drop occasionally as the fan comes on and off. When your thermostat is not working properly or is stuck closed, this will not allow the coolant to properly circulate through the engine, which may cause the engine temperature to fluctuate erratically or in some cases just remain hot. You may also have a water pump that is beginning to fail. Water pumps often times will begin to produce a bit of a whining sound when they are starting to fail. A common problem also associated with this is the water pump may begin to leak around the water pump shaft due to the seal being damaged. In addition to leaking around the pump, you may have a leak elsewhere in the cooling system coming from one of the hoses going to or from the radiator. Lastly, you may have a failing cylinder head gasket allowing coolant to leak from the water passages into the cylinders resulting in the coolant being burnt in the combustion chamber with the fuel. If this is the case, you may also notice a bit of white smoke coming from your exhaust which is a product of the coolant being turned into a steam like vapor. I would suggest having an expert from Your Mechanic come to your home to diagnose your cooling system.
My 1998 Buick Park Avenue only runs hot when in traffic or just idling. What’s the cause of it running hot?
ANSWER : Either the cooling fans on the radiator are not working properly or the radiator is plugged up to where there is a restriction when the engine’s water pump is running at a slow speed. If you suspect that the radiator is plugged up, try running the engine at a higher rpm when stopped and the transmission in neutral. If the coolant temperature gauge drops, then the radiator needs flushed or replaced. If the engine tends to not cool down but rather overheat, then the cooling fans are not working.
Then you would need to check the cooling fan relay and see if its clicking on. If the relay is not clicking on but there is power to the relay, then the cooling fan relay needs replaced.
If the cooling fan relay is not clicking on and there is no power to the relay, then there is a break in the wiring from the fuse box to the relay or the cooling temperature switch has failed.
If the relay is working and clicking but there is no power to the cooling fans, then there is a break in the wiring from the relay to the butt connector. If there is power to the motors but the fans are not coming on, then the cooling fan motors need replaced.
If you need further assistance with your engine overheating at a stop, then seek out a professional, such as one from Your Mechanic, to help you.
