Tranny? Click.

ill be in 1st, 2nd, gear and 2500 rpms and let off the gas and it will make a clicking sound that sounds like metal is hitting metal. also happens when i start off in reverse and then start forward again. any help?

Could be a few things that come to mind. Check your engine and transmission mounts, make sure your exhaust is secure, and take a look at your u-joints for play. Any one of those is probably just as likely as the other, but that's the areas I'd focus on first.

make sure there is no scoring on the driveshaft from the e-brake bracketry.
