EVO X - Difficulty getting in to 2nd gear from 1st.
It may be mechanical but I guarantee its the fluid. If were actually mechanical the car would do it regardless of car operating temp. Just letting the car idle shouldnt do anything...thats not warming up the tranny fluid. I roll down my driveway and leave it in second, then when I shift its good. I actually just skip 2nd sometimes in my car until its warm if its really cold out. Either way its the cold flow properties of the fluid. Mitsu have never used a fully synthetic tranny fluid so notchiness when cold has always been a problem.
has anyone tried stomping the clutch pedal to the floor very quickly before shifting? that's how I've always had to shift my VIII. it doesn't like to shift without the clutch almost through the floorboard even though the engagement point is very high. not even after getting the ACT clutch...

Perhaps you have an issue?

Boostez, the comment that I made was that even though the synchros creating a notchy feeling may be mechanical, that it's most likely a result of trany fluid that isn't well matched to the synchros. The notchiness does go away once the car is warm for the most part, in mine and most others. Only a few people seem to have the notchiness even when the tranny is warm. Who knows, but I've driven my friend's 9 on several occasions, and his feels just as notchy as mine when it's cold. Once the car is warm it shifts fine as long as you shift quickly, which is just how the synchros seem to be designed. Finding a better matched fluid will resolve this, I feel quite certain. This is just my guess, so I am not claiming to know for sure, but judging from how the synchros tend to like hard shifting and have no trouble at high rpms would indicate that the problem is not mechanical but rather just a fluid issue. We will see I guess. Have you driven a X yet? You probably should before you comment further on this issue. I think you'll actually find that once it's warmed up it shifts better than the 8 and 9 did.
One thing I also found is that petroleum fluid has worse cold flow properties than a full synthetic. But usually it means that a fluid that shifts stiff when cold is less prone to shearing when very hot (in most cases depending on viscosity.) You can stick in fluid that flows good when cold but when its hot it thins out too much (ie synchromesh). So basically you are giving up a little shifting smoothness to have a more stable fluid at high temps. Which is for anyone who races an evo knows how hot the trans temp fluid gets.

Damn machron, thats some serious miles!!
I have to say, having driven both cars, the issue in the X doesn't seem as bad, to me at least, as the stock VIII. However, after my tranny rebuild (thanks to Mitsu recall for all Evo VIII's) . I really dont have much issue with the shifting at all to be honest, though its just not super smooth all the time, and I only have the slight resistance going to 3rd gear, and I have no issues with 2nd. It also seems to be less noticeable as the miles pile on, but that could just be me getting used to it.
