Going to change out fluids (13.6k miles). Some Questions.
My car was sitting (was being run every few months) for around 4 years until I started driving it 3 months ago. My tranny is extremely notchy (like every other evo), and I can't stand it anymore. I bought a weighted shift-knob, which helped a little, but not enough.
I'm going to have it done by my mechanic, and just want to make sure I am purchasing the correct fluids & getting the best bang for my buck.
Items:
Is it only possible to buy the tranny and TC fluids by the gallon? If no, am I getting my best bang for my buck by buying them by the gallon?
I've read about some different kind of tranny fluid "mixture", other than stock. Should I go with that instead?
Should I change out the ACD and rear diff fluids as well?
What would be a fair price to have all of these fluids changed?
Evo maintenance isn't cheap

The Redline cocktail mix is what I use for the transmission and it has worked great for me so far. I use the Diaqueen in the rest of the drivetrain. You can use pretty much any synthetic oil in your engine along with any quality oil filter.
Don't be hung up on brands as I have yet to see any definitive evidence that one oil is far superior to others in all test. People on here will rep Amsoil or whatever brand they use because they are bias, but I can say I've used them all and have suffered no ill effects on any of them (I thought Royal Purple made my engine a little noisier, but that could have also been in my head).
13k miles is LOW mileage!! Pics?

Nothing impressive:
Ok, but do I want to replace the rear diff and acd fluid at this point? Would there be any noticeable symptoms?

Go to walmart for Mobile 1. I have used Mobile 1 on my car since the day I have had it. NO issues here. Car has 134K now.

I use Rotella T6 and OEM oil filters, each change is about $28 or so. My next change I'm going to send out the filter and a sample for analysis, just to be safe.
I used MT-90 in my trans and it's been wonderful, changed about 5k miles ago. I used Redline 75/90 in my TCase and rear diff and it seems fine, but I'm going to swap that out for Diaqueen in another 5K since that is what is recommended. I don't drive it so as to be hard on the diff or tcase so I'm sure i'll be fine with the redline stuff in there for 10k.

ACD is a different fluid then the TC and rear diff. It is basically ATF.
There is a procedure for how to replace the ACD fluid but at 13k miles I wouldn't think it needed. Check the how to section of the site. I have an 03 so ACD here but it requires powering pump on to get old fluid out and priming new fluid in.
Rear diff/TC and tranny are easy as drain and fill.
The cocktail mentioned previously is for the tranny not the motor.

5w30 seems to be better for colder climates like NY.
If these fluids are really that easy to change... maybe I should man up, buy some good jack stands, and do it myself. I have a greddy ti I need to install anyway.
However, if the labor for the fluid changes would cost less than $100 I would almost rather avoid the hassle and have the mechanic do it..

only thing I would be worried about is a mechanic filling the ACD transfer case up and when it flows out (full) he torques the fill bolt back in and calls it good... The ACD transfer case will act full at first, but it is really only like 3/4 full and you keep adding fluid after it settles or after you spin it around. I've seen a few people complain of TC whine after a fluid change and most of them are because of it not being filled to the max. Just something to think about or mention to the mechanic who does it.
I'm not worried about the mechanic; he is the kind of guy who will not do something he is not comfortable with and refuses to do anything slightly illegal (bad for me when I install my exhaust).
Maybe I should just go to Ivey for this...?
