I've recently purchased a 95 Avalon XL. When checking the tranny fluid, I have a hard time getting the dipstick back in all the way. I've checked the fluid twice now and both times, it has taken at least 5 minutes of poking to get the stick completely in. Also, I noticed that the tip of the stick is a bit battered. Is there a secret to replacing the stick? Is this a sign of a problem? The owner's manual doesn't offer any information on it. I'm on the verge of taking it to a shop but if it is something simple, I'd rather save myself the trouble and expense.
