Just wanting to know the proper way to check the auto transmission.The dipstick has a hot and cold mark but do you check this running or not and at low idle or high. Thanks | ||

Hi Barry, I'm sure there are some people more in the know about this than I, but according to my MC9 Mtce Manual, there is a reference to checking the auto transmission fluid level after changing the filter, by first running the engine to check for leaks. There is another reference to checking the auto transmission fluid level by maintenance personnel only in the Operators Manual (not much help there) There is also a reference for detailed automatic transmission info to refer to the DDA specific manual.

Yes I read in my Manual about checking the level but they don't tell anymore than that. Barry | ||

You check it at idle at engine operating temp and in park with bus level this per the Allision manual | ||

Yup, what luvrbus said. You can use the cold marks to give you an idea, but best measure comes from the reading against the hot marks after a long enough drive to get it all warmed up. Down the highway for 30 minutes, not around the block. happy coaching! buswarrior | ||

Just thinking (I know that is dangerous). What about checking fluid as above and making sure it is correct level, then after engine/transmission are cold and not running, sitting level mark the dipstick to indicate that level. Wouldn't this allow a way to check the fluid during morning pre-trip when fluid is not at operating temps? | ||

I wish we could Jack. the trouble is whether the fluid will drain down to the pan from the rest of the transmission, particularly the torque converter. The rate at which, and the completeness of it, cannot be predicted, and maybe even depend on the position of the internals when they come to rest. Rats. happy coaching! buswarrior | ||

Oh well, it sounded good before I started thinking about all the factors involved LOL Jack |
