I have access to a lift net week so I thought it'd be a good time to change out my differential and transmission oil in my 87 4kq. Anyone have any tips on this? A quick look through Bentley didn't show much info. I'd like to hear any suggestions on the ideal oil weight to use in New England, also hoping to reduce the notchy feel I have putting it into gear. Thanks, Paul 87 4kq 86 944
