75-90 ehhh....i went 80-90 works great

So I took a few days off, and had to do some maintence, changed my tranny gear oil, my rear diff fluid, greased the shafts, hit the frame with some black spray paint...

I know toy. calls for 75-90 gear oil, my auto place didn't have any, so went with a little heavier 80-90 dino oil and my tranny shifts much nicer. Not that it will harm it, might have slightly more drag but im not racing and the MPG loses are not noticalbe.

But all went well...

 

I noticed you live in New York. You may notice it will be harder to shift when it gets cold, but other than that it shouldn't hurt anything.
