That's assuming that the fluid level was correct to begin with. A lot of cars are underfilled from factory. My 2 Mazdas were, by about 0.5L. So if you drain and fill by the same amount, you'll still be low. You should check via dipstick.

 

Thank you for the info. Wouldn't all fluid level be good after PDI since Freight and PDI was paid for. It was $2,025 CAD if my memory serves me correctly. BTW, how do you check level of Tranny Fluid at 50 degree C if you do not have a thermo-reading device? At 50 degree C, would the temp gauge indicator pointing half way or just above the blue region.

Are you in BC?

Thank you 😊

 

In my opinion, I think you are unnecessarily concerned with the temperature of the fluid removed. Drain the fluid, refill with the specified amount and confirm the level with the dipstick.

 

Thank you for your input

 

I use a plastic paint pail from Lowes that has increments all the way. its in liters on one side. I get approx 3.75 L out every time. I do drive down the road and check the stick HOT to double check level. I do my oil and trans every 5k. I figure the 3.75 out of 8.1 liters every 5k will keep it cleaned up. Change the filter approx every 30k. Tried the after market gasket and never could get it to seal,always seeping,so I went back to RTV. I use the Casterol Transmax. I drained and refilled 6 times to get the old blue fluid out. Drove about 10 minutes each time to get a mix. Then I dropped pan and put new filter and RTV. Have drained and refilled 3 times since then. Once every 5k along with motor oil. Ought to extend the life of trans I hope. No issues so far. 100k on 2021 CX30 Premium AWD Turbo.

 

Hahaha, that's cool

You mentioned that you use an OBD2 Scanner for live streaming of ATF Fluid Temperature. May I ask what device you use so I could get the same one on Amazon.ca.

Thanks
