But it is an engineering problem when Subaru sells the same setup to markets that have environments where it would be detrimental. I agree with jg2000 as there is a CVT cooler and it's mounted next to the converter case of the CVT according to the service manual. and After Install 4 month i Remove the Tranmission cooler and i think the temp is normal in 165 -210 is very good for me. Vs a hill climb you spike temps for a short time, possibly only heat up a portion of the fluid in the system, then you have a down hill where you can cool things down pretty quick. The first method uses Nissan's special tool: KV311039S0. Seems General Subaru Community related. automatic transmission systems. From monitoring this site, I've found these CVT temp should be between, 185 - 235 F. Sounds like it's right where itshould be. industry SPECIFICATIONS Meets Dexron-IIIH, Mercon simply selecting the most appropriate gear ratio. I kept the trailer and cargo weight light for the first trip, total trailer/cargo/passenger weight was about 2,200 lbs. My experience is heat soak is the big struggle. In addition to fuel economy and reduced weight, they offer steady acceleration, smooth operation, and the ability to adapt to varying road conditions and power demands to provide a smoother overall ride. Can someone else who has one of these setups (Torque/whatever) and a Subie w/CVT check my work? data will be stored in protected databases on secured servers with restricted access). that it allows the engine to operate longer at a lower speed than conventional The variable diameter cones in a Subaru CVT are referred to as Variators with one considered the input and the other the output. VerticalScope Inc., 111 Peter Street, Suite 600, Toronto, Ontario, M5V 2H1, Canada. Watching the ScanGauge, I can see that temp slowly climbs while driving on the freeway. I agree, just making the point that a 20dF variation is the difference between "safe" operating temps and "not safe.". The fluid churns inside the torque converter, gears, bearings, clutch plates, and other parts and its temperature increases with the car in motion. 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. Accordingly, our policy regarding online privacy has been developed using the following guiding principles: Our dealership maintains a strict "no-spam" policy. I drive over sand in summer and this is deep sugar sand and things do run hotter. I just purchased a 2017 Toyota Camry with a U760E transmission. When I am driving spiritedly I have seen as high as 210 but it quickly dropped down to 205. You think all of the automotive engineers allowed this "problem to continue for 70 years and hundreds of millions of auto tranny setups? Another process that a CVT helps to iron out is the need for the transmission to "hunt" for gears. Won't rev past ~4k. They offer a unique manual mode via steering-wheel-mounted paddle shifters. I don't tow or go off road, just normal city and highway driving. For a better experience, please enable JavaScript in your browser before proceeding.

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. Adding a CVT fluid cooler would serve no purpose at all if it cools BEFORE the fluid passes thru this heat-exchanger. Perhaps the Forester warms the CVT fluid to improve low temp operation? That's 115C normal and 130C+ racing. If the vehicle is within 10 years old, most of these problems should be covered under Subaru's extended warranty. You've got questions. Another option is RWD conversion through DIY means or in the form of a purchased kit via MRT, Rocket Rally, or Kingpin. (V0200) and follow the FSM procedure for a drain-and-fill (car must be level and fluid at operating temp). The torque converter is not capable of transferring all of the input power and may lose up to 10% which increases fuel consumption along with transmission fluid temperatures, requiring the fluid to be replaced more often. pedals (no I'm finding that when the car has to idle for longer periods in hot weather is when the rubber banding of the CVT is at its worst. It is not unusual for a CVT equipped vehicle to have better fuel efficiency than similar vehicle equipped with a manual transmission. Your car is safe when the temperature of the gearbox fluid hovers between 175 and 225 degrees Fahrenheit. Rather than using gears as in traditional automatic transmissions, Subarus CVT uses two fluctuating hydraulically actuated pulleys and a chain link. Some browsers incorporate a "Do Not Track" (DNT) feature that, when turned on, signals to websites and online services that you do not want to be tracked. Always treat cars with mechanical sympathy and take care of them properly. hmmm wondering how the cooler got fowled??? This is the normal operating temperature for a transmission. Cars run better with warmer fluids, not cooler. Rectify the problem before somebody dies.". My car begin to roll backwards. When the temperature crosses 250F, it hardens the rubber seals and leads to their cracking. This is also the point at which the combustion of air and fuel is most efficient, resulting in lower exhaust emissions. cvt monitor cvt temp cvt temp monitor cvt temperature forester transmission monitor subaru cvt subaru wrx cvt Related Products Subaru Turboback Exhaust System STI Sedan 2011-2014, WRX Sedan 2011-2014 $ 2,275.00 Rally Armor UR Mudflaps Black Urethane with White Logo Subaru WRX 2022 $ 189.00 3 Inch 2-Bolt Exhaust Gasket $ 15.00 Most vehicles with conventional control is in tune with changes in engine speed, maximising drivability and When you purchase through links on our site, we may earn an affiliate commission, which supports our community. . Also, at this temp there are no error codes or check engine lights.

Here's what I could find out about taking a fluid sample. I google'd it but since many WRX's did not have oil temp gauges previously, the choosing of whether or not they should install these gauges dominated the discussion lol. I just received my notice yesterday and was surprised because they claimed the deficiencies of the earlier years had been resolved. Go anywhere on the internet and look at the failure rate of the CVTs (Subaru has used 2, the 580 and the 690) and compare them to the failure rate of the older 4/5EATs. If you are accustomed to conventional automatic transmissions, you may equate acceleration with the sound or vibrations from the rise and fall of engine RPM and the shock felt while the transmission upshifts. The coolant is regulated by the thermostat, but engine oil temperatures and CVT fluid temperatures are only influenced by the coolant. In fact, overheating is such a major issue that it causes almost 90% of automatic transmission failures.

With the CVT, (Continuous Variable Transmission.) Actually,it's doing just what I would expect it to.At higher speeds the mating surfaces within the CVT are moving much faster and thus more friction is encountered which in turn generates more heat.In town these parts are moving much slower thus less friction leading to less heat. Our dealership may partner with select retailers and other companies at various times to provide expanded services to our site visitors. fast, you needed the narrow gear to go even faster. 6. 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. These sensations are what we have become accustomed to in both manual and automatic transmissions. For example, a popular tire upgrade for the WRX is 50 series 16" tire with a 24.1" circumference. It also provides superior cooling and excellent low-temperature fluidity for smoother operation in cold weather. Ford, Fiat, Nissan, and Subaru have all heavily used CVT transmissions . Personally , I doubt a 1.5" lift or a teardrop would cause any issue; we tow a 3000lb rig; before that we had a pop up with the Ascent and it was barely noticable. Doing away with the more complicated design may suggest that CVTs are less problematic, but that is not the case. The Fora platform includes forum software by XenForo. 2011 Subaru Outback F4-2.5L SOHC. Its not an engineering problem when used in the appropriate climate it was engineered for.
