I go over how to read your WRX CVT transmission temperature with your android phone. The app ActiveOBD can measure this figure on . My experience is heat soak is the big struggle. Thanks for your very useful blog! However, throughout the past decade, hundreds of customers have complained to the National Highway Traffic Safety Administration (NHTSA) about several problems relating to Subaru's CVTs. The Fora platform includes forum software by XenForo. Recommend it. 1) Its a CVT not a trans with clutch packs, different animal and hard to make a direct comparison between the two without a lot more background knowledge and data. Not an everyday occurrence, but something I do maybe once a month. Subaru engineers already told me that the ECU will pull boost and timing if it sees too high of oil temps. A manual transmission has a clutch that mechanically locks the engine output power to the transmission, while a traditional automatic transmission has a torque converter which uses hydraulic fluid to transfer power. RELIABILITY - Subaru CVT vs. Toyota Power Sharing Transmission. There is also a torque converter - to broaden the range of gear ratios and to ensure a smooth start-off. I completed my first long tow with my 2016 Outback Limited 2.5. A lower engine speed means better fuel economy. This will allow you to connect your phone to your vehicle easily. The Drives informational team has been digging through forums, recalls, and consumer complaints to get a sense of what issues you need to be aware of when buying or driving a Subaru with a CVT. Upon shifting to the lower gear the torque reduction request is cancelled and upon resuming a shock can be felt and the engine RPM will begin to rise within about 1 second. A CVT does not require a reduction in engine torque. CVT is short for continuously variable transmission. And it seems to stay around 218*+. When I am driving spiritedly I have seen as high as 210 but it quickly dropped down to 205. I've been searching for a secondary/auxiliary tranny fluid cooler for the Gen 5 CR-V CVT for a while now..no luck so far. Of course the colder the ambient temp, the longer it is going to take. I'll take it in after I get back to town next week. The coolant is regulated by the thermostat, but engine oil temperatures and CVT fluid temperatures are only influenced by the coolant. It's probably. Perhaps in technical forum, under engine/drivetrain. You may hear hissing or squealing type sound for a few seconds after shifting into any gear, the noise is caused by the transmission fluid inside of the CVT and is a normal operating characteristic. I installed a transmission cooler 19 row and i Check Temp Tranmision running at 150 i think it so cold . Think weekly. Would you like us to send you price alerts?

Should I try using a baffle on the cooler to bring the temperature up a few more degrees, or should I just run it at 168? With regular Mobil 5/10W-30, the oil will fall apart at 115C. Do some research and you will find that 175 degrees F is an optimal temperature for an automatic transmission to run at. That's a good rule of thumb, if you don't have a way to measure. My 2023 Wilderness is on order and I might end up towing 1500 lb trailer from time to time with it. Humidity 89%. At those temps recing oil is needed and it needs to be changed alot.

This left me with no power on a state highway that had speed limits of 75 mph. how can u get the triple gauge settings mine dont work. A Subaru equipped with a CVT will generally raise the engine RPM to a certain level based upon accelerator input and engine load. I have seen over 240F CVT-F temp in my XT and dont consider it a problem at all, as that has been when towing over mountain passes. fast, you needed the narrow gear to go even faster. A human can only pedal so fast, and with so much In simple terms, torque describes how much work an engine can do and horsepower describes how quickly that work can be done. gear to suit any driving style and road condition, while a stepped variable The fluid churns inside the torque converter, gears, bearings, clutch plates, and other parts and its temperature increases with the car in motion. Above 130C is too hot period. If the fluid is not in the correct temp range (95-113 deg F, 35 - 45 deg C) then it is Not Okay and the easiest way for the common folk like us is to use one of these wireless bridges and a program on our phones. Start with winding noise then gets worse very quickly, within one to two months. Fluid volume, vs heat soak over time, vs air flow/heat shedding ability.

Another process that a CVT helps to iron out is the need for the transmission to "hunt" for gears. If substantially all of the assets of our dealership are acquired, consumer information may be transferred as part of the acquisition.

The fact is, Subaru knows what they are doing and won't ship a new product without verifying the simple things. There is a CVT cooler (heat-exchanger) which 'normalizes' the temperatures of all three (Engine oil, Antifreeze, CVT fluid). It will simply change the gear ratio to match the accelerator input, the engine RPM will increase accordingly and no shift shock will be felt. VerticalScope Inc., 111 Peter Street, Suite 600, Toronto, Ontario, M5V 2H1, Canada. Improved protection of copper and bronze components. I believe you are correct! It has lowered the median CVT temperature by about 25 degrees.

There were 3 transmission options with the 2014 Jeep Patriot. As a general rule, oils have a fairly narrow normal operating range, roughly 160F-240F.. It's not likely that CVT's will operate at a significantly higher temperature than other oil lubricated equipment. It is possible to increase the number of gear ratios to overcome these design limitations, however in doing so the transmission becomes more complex, heavier, and contains more components which also increases opportunities for a component to fail. acceleration and lower RPM for better fuel economy while cruising. I suspect the fluid temps between the cvt and the old 5eat will run very similar. If your vehicle pauses or hesitates when you press the gas, the CVT could be malfunctioning. While it's by no means a poor design, it presents its own list of possible issues. Keeping it less than 175F indicates a healthy condition and ensures long mileage. Subscribers or site visitors will never receive unsolicited e-mail messages from agents working on our behalf. I don't tow or go off road, just normal city and highway driving.

If all the components are functional and you are driving at a normal speed, the ideal transmission temperature is 175F or less. gears have four or five different speeds. y0d40n3 Your FSM information is correct. I think that Temperature is too hot. Low 24F. The Lineartronic TR580 is 100 mm shorter and 15% lighter than the TR690, and that is the reason why the . transmission shift -- it simply raises and lowers the engine speed as So by design the Forester CVT heat exchanger is reducing the life of the fluid by at least 50% off the start.

Nope. I left a message with the dealership, and I am awaiting a return phone call to have the vehicle assessed.. As a result, these seals leak both pressure and liquid. There is a compromise between the lowest gear ratio which improves acceleration and the highest gear ratio which improves fuel economy, in an attempt to keep the engine RPM in this range of efficiency. While many feel it's a safety risk, countless people think they're rock solid. Besides, you can use a temperature gauge to find out how hot the transmission is. When doing so, we will make every reasonable effort to avoid excessive or irrelevant collection of data.
