at what mileage/time interval would you guys recommend to change the tranny and diff oil? Every 30k? 60k? Every 2 yrs?
I couldn't find any info in my owners manual. So what schedule do you go based on? And what brand of tranny/diff oil do you use? I used good 'ol Redline D4 ATF for trans and Redline 75w90 for diff. Works superb. Just wanna know your recommendations and suggestions. Thanks.
