There's an Amsoil dealer here in Longmont, I'll pick it up after work and do the change. Maybe Napa has it too I'll check here on my lunch break. Pennzoil Synchromesh worked pretty well for the month or two I had it in there, but definately died out on me pretty quickly.
ive been through 2 stock transmissions. Im only pushing 340whp. I drive it hard on the wknds and track it once a month(launched at the track of course). If you just "drive" your Evo the stocker will last a long time, but for those that actually launch and track it, it wont. Plus the stock synchros and internals aren't the best from he factory. Once i got my 3rd one built by Shep i havent had any issues and its put up w/ the abuse nicely. It shifts smoother than stock and i most importantly it got rid of my annoying 5th gear grind. One recommendation, is IF you decide to get it built, do it when your tranny is decent. It will only cost 800-900bucks plus shipping. I destroyed my output shaft and 3rd 4th gear set which added a significant amount... resulting in a 1600 rebuild. Which still wasnt that bad considering. Ive had 3 buddies get Shep rebuilds when they had no issues w/ the stockers and reported huge driveability improvements, making them well worth it.
oh ok, I thought you said you had been... my mistake.. I would say then if you are smooth with your shifts ( not slamming into gear and such ) you should get pretty decent amount of life out of it even with the added HP. I always heard the stock drivetrain was pretty strong.

I beat the **** out of my car daily, and was wondering if or when I could expect to have my tranny break on me. I've had issues with getting into gear when it's been cold outside, the tranny fluid needs to running hot before my car feels butter smooth. I know that is pretty normal, regardless I'm gonna replace the tranny fluid here soon and see if I notice any improvements. Car has almost 45K miles on her now.
