country15boy98 Posted April 14, 2015 Share Posted April 14, 2015 I have been searching the internet for awhile for a MTF for a 1998 Subaru Legacy Outback. Could anybody tell me what tranny fluid this car takes? And how many Quarts? Please and Thank You. Quote Link to comment Share on other sites More sharing options...
Fairtax4me Posted April 14, 2015 Share Posted April 14, 2015 GL5 spec 80w90 gear oil. Takes just shy of 4 quarts. Don't use synthetic because it's too slick for the synchros. Subaru has a new fluid called Extra-S that has helped with shifting issues on these transmissions by its costs as much for a quart as a gallon of regular gear oil costs.
