judging by pedal feel and release point of clutch, i'd assume my pedal is still okay. with the car off the ground and clutch in @ idle, the wheels don't spin, so i don't think it's dragging. no clutch slippage during accel.. but i haven't checked in quite some time. hm... maybe i'm due for a checkup LOL
Does Motul MT90 shift smoother than Redline MT85 or MT90?

It's been awhile since I've posted anything on my post I started. I like to thank everyone that loves the 6 speed, and giving advice on what they have done to keep their 6 speed going. I have always used amsoil, but thinking of trying the motul once I get my Evo back up, and going from my build.

Do not use any 90wt lubricants in your 6 speed. The 6 speeds are designed to work with 75w85 GL-4 lubricant or direct equivalent. The 75w90 stuff is for the 5 speed, and has been known to tear up many 6 speeds that thought they could use the same.
I've always run OEM Diaqueen, or Castrol Syntorq in my 6 speeds. The Syntorq is identical 75w85 GL-4, but it is a full synthetic. It's the OEM fluid for the Neon SRT-4 as well as some other MOPAR vehicles. On my first IX MR I had 360whp, and 182,000 miles on my 6 speed with zero issues. I launched it, autocrossed it, and beat on it. The second owner upped the power to near 500whp and was still on the original stock 6 speed with over 200,000 miles.
I'm currently on my second EVO IX MR with 143,000 miles, but I had the transmission replaced with a TRE 6speed at around 100,000 miles. I have used Syntorq and Daqueen only in this one as well. Zero issues so far.
1st through 3rd gear in the 6 speed are every bit as strong as in the 5 speed. The issue is heat, and 4th gear. There are 6 gears in the same 5 speed housing, so it can't hold as much fluid, and has issues dissipating the heat. This usually happens during road course racing, and 4th is usually the gear to go. If you want to protect your transmission, get a transmission cooler installed. This will allow for more fluid, and more cooling, and should just about fix the reliability issues of the 6 speed. For daily driving, and autocrossing though, you should be fine.

You're wasting your time telling people to use OEM trans fluid. Every builder I've emailed recommends OEM yet people insist on using other fluids.
I'm good at 127k miles on nothing but OEM.
I haven't looked into the SRT stuff, though I have heard of it. Probably cheaper too.

The SRT fluid is identical, but fully synthetic. The price is close to the same, but it's much much easier to get a hold of because every Dodge dealership keeps the stuff on hand. Chevrolet also has the same fluid sold under a different name. No one ever has Diaqueen on hand, and it's always a pain to order, so I've always just gone with the Mopar fluid.
I will say the Castrol/Dodge fluid losses it's "touch" or slickness about twice as fast as recommended refills. So I change out ~7500 miles instead of 15,000 miles.
The SynTorq LT is an interesting fluid. LT stands for low temperature, which is what it's designed to do...keep temps low

Yup. Castrol Syntorq LT. It's also the OEM Viper fill. It solved my 2nd gear notch/grind when I switched over from the DiaQueen. I'll be putting it in my Shep 6 speed. Shep recommends the RedLine lightweight shockproff, but someone on here said it clogged up his 6 speed and the trans went kaput.

Very interesting you guys wait that long to change your fluid. The most I've gone is 5-6k miles in Amsoil. So I guess as far as longevity, I don't have much insight for the fluids I use. I like changing mine at 4500-5000 miles. Just piece of mind for me. Plus my Trans is still in one piece, so I guess it's working in my favor
Worst case scenario, you're wasting money, But really, what is peace of mind worth? Lots of people spend far more money on their cars for "just in case" reasons. I wouldn't worry about excessive fluid swaps.
