Hi , How do I find out what tranny I have in my 1998 Grand Voyager 3.8L - LE.

Had no problems so far. 179K. How often do I need to change the oil?What should I wach out for?

Thanks in advance.

You have the A604 sometimes referred to a a 41TE, I change the fluid and filter in my '96 every 30,00 miles with ATF+4.

Don't tow a heavy trailer without a tranny cooler, and don't tow in overdrive gear. That's how I killed mine.

Also, be sure to use the right tranny fluid, +4.

Thanks for the info guys
