That's 115C normal and 130C+ racing. Based on all three winter months, however, the Free State was the coolest federal state - with an average of 1.9 degrees. When under moderate to heavy acceleration the Transmission Control Module (TCM) continuously adjusts the gear ratio to maintain an engine RPM that produces the most torque and efficiency, and may maintain this RPM for quite some time. About twice that length of time, oil is up into the ~210 range, which is normal operating temp. If all the components are functional and you are driving at a normal speed, the ideal transmission temperature is 175F or less. When at a steady higher RPM during acceleration, the frequency remains constant and may resonate. during operation. I would think it'd be the opposite of the cooler was fouled. For a better experience, please enable JavaScript in your browser before proceeding.

I'm assuming it is related to elevated CVT temp but want to measure and verify. I asked Honda and they refused to tell me. provide the most appropriate ratio for a given situation: lowest gears There is a CVT cooler (heat-exchanger) which 'normalizes' the temperatures of all three (Engine oil, Antifreeze, CVT fluid). According to the investigation, the likely source of the seepage is the sealant used on the CVTs oil pump chain cover and the input shaft oil seal. Due to the linear nature of the CVT, the torque converter is able to partially lock-up at approximately 9 km/h then lock up completely at 24 km/h, and remain locked as the gear ratio changes. .
