Ok, I am getting ready to start saving money to do little things to the truck. Just bought a house in October, so I am a little broke. I have an LS1 cam in the garage I want to install for a little extra power. I also want to get Allen's tune. I am not sure what I need to do with the transmission, It has almost 90,000 miles on it, and I havn't even had the fluid changed (I know someone beat me ). My first step is to change the fluid and filter, but after that I am not sure.

Thanks,
Randy
