Your welcome. I'm glad so many people find it useful.
I just got sick of always flipping through those schedules to figure out what I needed to do. Of course I was always in weird situations, like I'm at some mileage, but the manual says to only do the engine oil and diffs, but I didn't do the ATF at the last interval because I did it early previous time, but I did do my rear diff when I did the rear disc conversion last week........ugh...
I modified the spreadsheet so it calculates how many miles or months until something needs servicing. I was using the program and found it annoying that those X's would suddenly pop up unless you kept a close look at your maintenance log.
I think langer1's site is down, so PM me if you want an updated copy of the spreadsheet.
