My question is this...for my RX330, I had a heck of a time getting the fluid to the right level. For instance, I measured specifically what exactly was drained, and put that exact amount in, and now, when the engine and trans are completely cool, the ATF level is an inch and a half over the "HOT" notch on the dipstick...I notice that the transmission, when cold, shifts abruptly but then when it warms up, it is as smooth as it always was...
I honestly can't remember before I changed the fluid if the trans shifted abruptly when cold or not...that's what happens when you get old.
Bottom line: Do I have too much fluid in this unit???
On a level surface, at operating temperature, and while the engine idleing, the ATF fluid level is right at the highest notch of the "HOT" reading, EXACTLY. Which leads me to believe I am good to go.
My "over the top and maybe reading in too much" question is: Why is my level a good inch or so above the HOT level when the engine is COLD??? There must be a purpose for the "Cold" level on the dipstick...
Thoughts appreciated,
