1999 dodge ram 1500 sport limp mode?

I just went out and bought my very first ram truck (after owning ford my whole life) it's a 1999 1500 with the 5.9 gasser in it and I abosolitly love this truck! Well at lest I did tell it went limp… I was driving to the lake with a few buddy's on the freeway and I was just crusing at about 75 when al of the sudden my truck high reved and wouldn't go faster then 35-40 I've done some asking and some research it seems like it's the govner presser switch and cylonoid but That's just what I read online. I don't just wanna through parts at it and wast money so any ideas?
Little more In to it.
Around town driving it dose awsome but I'm only geting about 6 mpg and it won't shift out of 2nd gear it just reves about 2500 rpms and wines. I can't go faster then about 45 down hill and it will shift from 2nd to 3rd if I let of the gas but as soon as I go to give it some throttle it will down shift. Could really use some help here

MAZDA 3 ATF fluid. WHICH ONE?

So i'm planning on doing a drain and flush my ATF on my 2005 MAzda3 2.0L, auto transmission with 123K miles.
The dipstick and also owners manual says "ATF M-V" and by the research I was doing on the internet in forums etc it means "Multi-Vehicle" and NOT "Mercon 5" which is different type of ATF for Ford vehicles… But am I right?
So, I went to the parts store in town, and they only have these 3 types of ATF, the Synthetic is 50% more expensive than the other 2.
Can I use either type?
The non-synthetic says on the quart bottle:
"For use in vehicles previously serviceable by DEXRON III & MERCON Brands"…
Any suggestions on what type of ATF should I use? Or can I use either one?
Here is the youtube videos that i'm looking at to do the flush:
Thank you very much for sharing any suggestions!MAZDA 3 ATF fluid WHICH ONE - 1

How to rebuild an engine for better MPG?

I'm gonna rebuild an 83 Lincoln Mark VI, now I know what most people think about Ford but I got it because I had one when I was in high school. People like Cadillac I like Lincoln. It runs good but its been sitting for 2 years in a barn, so before I start buying parts for the engine. Is there a way to rebuild the engine for better MPG?

Good 4wd vehicle for at or under $8500?

This will be my daily driver but I don't need no lixury 4x4. What Id like is either a truck or mid size suv. (No tahoe or suburban haha). I'm not a ford fan. Would like somethin that is relible and under 130k miles. A truck would be preferred but here are my priorities if I may.
1) reliable, good drivetrain, gonna last me past 200k
2)under 130k
3) 4 liters or better
4) common model (easy to find parts)
5) 2000 and newer
