1 1/2 month later after switch from RP to RL, this is what I got.
Used to have RP Max Gear in transmission early on, within first few months. Then, ordered on-line MT90 and put into transmission when I considered these comments here. Now, the transmission has the famous noise when the clutch is out.
Seriously, the noise sounds like a pathetic robot. Like a kid's science project robot that has just run out of batteries and can't get back up over and over again. It's terrible!
So would you rather do RP MaxGear and have a smooth sounding transmission, or switch to MT90 and get some grinding noises, and surprisingly according to some theory it is MT90 that is supposed to be better for your transmission?
Now, the third option needs to gain some more momentum. 50/50 mixx RP/RL. That's going to be the new trend. You read it right here on rx8clubz.

Maxgear is the wrong kind of fluid for the transmission. It's how I lost my transmission. It will not cause your transmission to die right away. In fact, your transmission will feel great. It will take years, like mine did, till your synchos start to show signs of wear and will grind as you try to shift.

What about

Amsoil Synthetic Manual Transmission and Transaxle

I just switched to Amsoil myself. Using the same stuff as Mysql for my transmission and Severe Gear 75w90 for differential.
So far impressions are good. The noise while the clutch is engaged and engine at idle is noticeably quieter, almost gone. The shifts feel good. Haven't tested it during cold weather considering it is summer and all, but it is easier to get into reverse and 1st gear before it is up to operating temp. Overall it is too early to really tell, but it seems like it is a pretty good choice and if it continues to perform like it has been for the past month I would definitely use it again.

I use MT-90 for tranny.
and Mixture of Maxgear & Mobil1 75w90 for rear diff. reason why was that cuz when they did my clutch last time I ran out of RP maxgear for rear diff. then they sell me a bottle of mobil1. so far so good, but I will switch it to Red Line 75w90 later this month.

Has anyone had any trouble with RP in the rear diff? I've read lots of posts saying how RP lead to grinding problems in the transmission, but nothing particular to RP screwing up the rear diff. If anyone has any comments as to why using RP in the rear diff and RL in the transmission is not a good idea, please tell me before I screw something up! =) Thank you!

I probably skewed the results as I'm sure a lot of you could care less about ATs, but I voted RP intending to cover their Max ATF product. It's good stuff.
I haven't done my differential yet. Not enough research to make a decision... it'll either be RP or RL... heck, I don't even know what grade to use at this point.

when i was going to change otu my OEM Transmission and Diff to RP, i did not because Yoshiya at the local shop here in OC said he just worked on a few transmission that failed and used RP... I choose Redling jsut to be safe for both and it is perfect for far.. i am ready to switch out again and probably will use redline again, was thinking about going back to OEM just in case, but i think Redlin GL4 is fine.

get the synthetic, shockproof should be reserved for racing only because it needs to be changed often
