Transmission fluid: Ford Motorcraft xt-m5-qs
Has anyone tried this in their FD? I put it in my supercharged miata and it is AWESOME. I put neo-synthetic into my FD and it's alright, gets better when it's hot. If it makes my FD shift like my miata I will be very happy.

Not that I've heard of. Check the specs on it, it's worth trying out!

IMO, there's more difference in ease of shifting (synchro performance) than durability performance. The OE trans lube was good, Valvoline 75W90 synthetic not good, and the NEO synthetic was better than the Valvoline, and close to the OE in shifting ease. I still would like it to shift better cold than it does with the NEO.

If you try it let us know the outcome. Over the years I’ve tried various oils for track use. Used Amsoil for a number of years as they made a specific GL-4 trans oil. The last couple years I’ve used Neo RHD which has seemed to hold up better to track abuse. Both shift roughly the same on the street.

I've used it in my Mazdaspeed 6. Unbelievably fantastic stuff. I have an extra quart sitting around that I'm going to put in the FD when I get around to ordering more. Really expensive stuff, though.

My 8 shifts the same ( no problems) with OE or NEO. FD with NEO has a tougher 1>2 (when cold) than I remember vs previous fluids (i.e. OE, RL MTL); that, or maybe I just forgot about past cold shifting.

Put some more street miles on the car this year and would rate cold weather shifting as “ok”. I have to be very deliberate and slow going 1-2 shift to keep from forcing it and/or having some notchiness going into 2nd. Once warmed up no issues. I’ve continued with Neo because on track use but interested to hear if anyone has put the motor craft through similar abuse.

I've been wondering about this in the FD trans as well. I ran it in the RX8 for about a year and it felt good, but introduced a pretty strong trans whine when I put it in that persisted the remainder of the time I owned the car. The transmission had 100,000 miles on it and I had used Pennzoil Synchromesh previously though, so it's possible that the sound was just introduced because of damage from a previous fluid setup and the flush of any kind of new fluid could have made that apparent.
Honestly I'm probably just going to do it since I put the Pennzoil stuff in the FD as a temporary test and am not liking it (way too thin for the FD IMO. Will report back if/when I do!
