t 45 tranny question

my 01 has a t45... car has 110,000 miles and if i try to shift it fast it'll grind and not go in gear.. i have to shift very slow and smooth then it works fine. Did yours have a problem like this before it broke? I'm thinking maybe my syncro's are shot.
 
no mines always shifted smooth but ive had new syncros put in mine awhile back but that does sound like a syncro problem i just keep breaking shift forks this will be the 3rd time ive had my tranny out replacing stuff
 
Sure, you can make the forks stronger, but the syncros and blocking rings will be the next thing to go. So I don't think you need a super heavy massively strong fork. You still have to be careful with the tranny.
 
I put those billet 3rd/4th teeth in my T45 to replace the stamped steel ones. I got them from Astro Performance. I couldn't really find any parts to beef up a T45, that's all I found. I mean, they had a 26 spline input shaft but I wasn't spending the big money on that.

Other than those 3 tiny teeth, my T45 was stock and I ran that for years with a blower on my 96 Cobra with no issues. You just can't miss shifts and power shift. I ran mine at the track a lot and did a lot of street racing and never broke anything.
