Over 5 years, twice my fluid has overflowed onto the exhaust and burnt off, causing great panic and billowing white smoke. This time fluid smells burnt, as I still had 1000 miles to go.
I suspect the torque converter is not locking up, though the rpm stay constant and it appears to work fine.
Also related is the fact I dropped from 25mpg+ to anywhere between 15 to 20mpg over the five years last, on rare occasions getting back to 27mpg on long journeys (only two trips to Florida-NC-Florida in 5 years).
I am going to drain fluid and replace. Read lots about don’t use anything but Honda DW1 but thinking about aftermarket synthetic fluid?
All in depth suggestions are certainly welcome, as I am in a quandary. The mpg had me for a long time, but now think the tranny boil off (all over the engine bay) is linked. Done about 60k with this issue mpg.
