I found out today that my trans wasn't rebuilt very well because it doesn't want to stay in overdrive and 1-2 shifting is becoming rough. Good thing I have a warranty...

Also removed the running boards.

Just did brake light mod to light up both bulbs.



Now just parking lights,


now with the brake lights,


Was pretty simple after all. Now about to wash her up.

Had my truck tuned yesterday. im really pleased with it.. now it has some pick up an go an the trans shifts awesome!! The only bad thing is the guy couldnt figure out how to adjust the speedo. Something about the 99s being the first year to be flashable. Any thoughts on this? He did give me a discount because of it. and this is what he used http://www.hptuners.com/
