FWIW, I know the techs at my Suby dealership and they say for the tranny, drain and fill every 15K. All of the metal flaking and bits settle to the bottom of the tranny and are easily drained off with a normal drain and fill. Plus the drain plug is magnetic to catch the very small metal debris. They've all said that a flush is like kicking a dust pile, causes all the little bits to move around the tranny and get back into gearing. Drain and fill I shall

How many quarts to drain and fill a 3.6L TRIBECA engine ( even though they don't get it all out) and how much do they charge for fluid and labor, if you don't mind asking him to give me idea?

If you can thanks!

$135 for a drain and fill on our H6 motor using 5Qts of Subaru ATF. Do it yourself for just the cost of the ATF for about $50.00+/- :tup:

Is it hard to do tranny DIY?
I thought our trannies were every 60,000 miles as per SUBARU CORP recomendations?

Not at all...actually very easy. I've been doing all fluid changes on our 04' WRX, 03' Impreza Outback Sport and now will be doing the 09' Tribeca. It's just as easy as the motor oil.

- Pull the Dipstick
- Pull the Drain Plug below
- Drain, Drain and Drain...
- Replace the Plug and Torque
- Fill-er-up through the Dipstick hole (use a funnel extension...long)

TaDa...just saved your self $70+

SOA always has a set standard of "Guidelines", but I listen to the tech's. They are the ones who do all the Warranty Work and see what really happens. They say 15k...I'm down with that. Plus I love to wrench
