I have a b18c1 and my tranny grinds 3rd and 5th gear. I was wondering what my options were?

Replace the gsr tranny.....

Buy a Type R tranny.....

Or, rebuild my current tranny with LSD....

How much would rebuilding the gears with LSD run me $$ ?

I know I can save up for a type r tranny as long as I save my $$.
So money isn't an issue as long as this tranny holds up.
