ive read the od lockup witch mod post but have a question for those with this mod ---- if i put it in D position and tip on the siwtch at 10mph will it shift all the gears without blowing anithing --- whenever im drag racing or driving normally??

 

It will shift through the gears going up, but it won't down shift. It is also really hard on the shafts in the stock trans to be doing locked shifts especially at full throttle.
