1998 Subaru Legacy Outback 5MT

Featured Replies

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.

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.
