[danteisme]

im gonna flush my tranny out pretty soon and put a new filter and gasket in it. my tranny has about 100K on it. my friend told me to add a bottle of the lucas tranny stuff to it to help it shift smoother and last longer. good idea? also, what kind of auto tranny fluid should i use?

Chevy don't recommend additives besides selected lubricants for the mechanicals ever. There is a reason, they are a high cost waste of money. Lubes only lube they can't rebuild your tranny or make it handle above design loads.
