Tremec TKO, Shifting problems

[sinned]

I am using a Lakewood bellhousing and the guy that installed it said that they checked the runout. I'm not sure what the tolerance was though. I am running GM Syncromesh too. Currently I have about 1000 miles on the tranny. It's wierd because sometimes it shifts fine and sometimes it grinds. Maybe I'm a dumbass and am not shifting well enough.

Always be careful of what they guy you paid to perform work says. They will almost always blame everything under the sun before agreeing they made a mistake and have to re-do some labor for free. I would ask exactly what he measured the bellhousing at. If he actually did it I'm sure he wrote the numbers down somewhere.
