2000 LS1 Jerking into 1st and 2nd gear
 

I have a 2000 LS1 that is jerking pretty good when it switches into first and second gears. It has over 100k miles. It is under warranty but they cannot see it until Monday. Anyone have any idea if it is safe to drive until then?

under waranty dont worrie about it it breaks the set ya up with a new trany

When the warranty is still in place, and being honoured by the dealership -- best bet is to let them do their thing, and don't mess with it. As far as driving between now and Monday, I'd go only if an absolute necessity ...
