I spent 1400 to get my tranny rebuilt with the g-force kit. 950 for the kit, 170 for rebuild kit, 90 for new (stock) 5th gear, and 250 for labor at a local shop. Oh and this includes all the shipping. Oh but, you need a 26 spline clutch disc so you may want to get a new clutch while your at it. But then again you have to go that with the tremec too. I just got a new spec 26 spline stage 2 disc for 100. Basically doing the tranny this way, is just like removing and replacing the clutch and trans. Theres no funny business about it. Also, tremecs are to heavy for me. Adding 40-50 lbs. to the front by andding a TKO was kinda unacceptable to me. I'm trying to balance the car as much as possible and that would just upset all that I have done so far. So for me it was an easy choice.
