I have a 98SS with a automatic and I am looking at putting more horses to it. Should I get a better torque converter or will I be ok. Or should I look into going with a 6 speed? I also have a humming sound when I am on the interstate and traveling at a constant speed I think it is my drive shaft but not sure any idea's would be great.

 

I'd sure refresh the transmission with some really good clutches if you're going up in power. It's much cheaper now before you break things internally.

 

Red Heartbeat, what do you consider good clutches, ive heard that the clutch into 4th gear is week, but for the other shifts what is a good clutch, where can i buy them, and about how much are they? Thanks.
