First gear is weird on WRX's. Rev-matching doesn't really help and it is easy to break the synchro.

My car "ate" 2 trannys. Thats when I bit the bullet and got a 6MT from an STi. Will report as soon as it gets here.

From what I have heard, they are very strong. Most of my "inside" info comes from Japan where 5MT's are known to break at about 350-400HP. So far, I haven't heard about a single 6MT that broke "under" power.

They are very strong. There are cast "rings" that act just like the block gurdle (sp?) and prevent from case flexing.

Also, 6MT has a hydrolyc lube system. It means there is a pump inside that circulates fluid and insure adequate lubrication.

Finally, diffs are in enclosed areas, so in case of a gear failure, the diffs will stay alive. Thats important, because the front Sure-Track LSD's aren't cheap.

check the fluid level. When dropping down hold it in first and it will slide in when its lined up (it can take a few seconds.)

The more you drop to first the easier is goes in.

That 6MT is a totally different gearbox, from the ground up. I hope it is better than my 2 5MTs as well.

Alex, I feel your pain man!
