My tranny grinds in 3rd gear at high rpm.
Also - It is very hard to downshift into second, and sometimes at high (7k+) rpm, second gear will not go in at all.

So - I have a hook up on labor and am going to rebuild tranny.
What do I need to rebuild it?
The 2nd and 3rd gear syncrhos

Will I need synchro sleeves bearings and synchro sleeves or can i use my existing?
