How often....

[sgmstr]

do you need to change your transmission oil? The dealership I've been going to says every 30K miles. Another says every 50K miles. The manual says every 15K miles I believe. FYI, I live in Los Angeles area so I can't follow maintenance schedule under normal driving condition.

Thanks in advance.

Per the owner's manual (which you should check to be sure), tranny fluid and filter s/b changed at 100K for normal service and 50K for severe service.

Keep in mind the manual doesn't reflect real world or should I say harsh driving conditions, which is what LA driving really is, I would be somewhat Conservative on the numbers.

I was once told by an old wise mechanic that you should service your trans at 40,000 and then never touch it again.
