Crit thanks for the explaination, I think I understand what is wrong in my
truck now. Are the syncros replaceable for my truck or am I looking at a
new tranny here when I take it to the dealer tomorrow? I tried double
clutching this morning and it works great and I get into third almost every
time with no grinding at all.
