Im looking to change rearend gears, and vlave body, and throw in the higher stall converter I have sitting around, i believe its a 2600-3000 stall somwhere around there. How hard would these items be on my trans, its a little worn but not slipping. I have a tranny cooler that I need to hook up as well. By adding these items do you think it would trash the transmission in a quick fashion?
