You could have gone with a Trans go Jr. before you limped it but now it really wont do you any good. Like Brian said build or turn it down as he always says you have to pay to play.

Whole kit. SunCoast III or SunCoast IV or ATS depending on what you want to spend. Do research on the trans you want everyone on here has there own personal opinion on both.

Many vendors have specials for trans kits that will hold a easy 450rwhp. Many kits from Suncoast and ATS will hold 500rwhp or greater, but the higher the price. Usually, expect to pay around 2500 for the trans kits.
