I've got pcm4less programming in my computer, LT4 conversion, stock tranny, 3.73s w/ zexel torsen rear, stud girdle, and 245 50 16s. I'm getting ready to install a TCI Super Street Fighter 3500 stall converter, and was wondering if I should install the shift kit that's been sitting on the shelf or not. The tranny shifts pretty dang hard now, pushes the rear out going into second easy, sometimes will chirp both rear tires going into third. I know everything is going to pretty much grenade soon, engine tachs out to 6000-6200 on wot shifts, if I get any traction I know the stock driveshaft and rear are gone, so what'da say?

Should I leave it on the shelf, or put it in for harder shifts?

 

My tranny shifted pretty firm stock also.. after the converter install the shifts turned to mush.

I installed the transgo well over a year ago and my stock tranny has taken me to 1.66 60' times and 12.0's... I would go for it.

 

Thanks, I appreciate the input, I'll be dusting the box off sometime this week.

 

I have Nitto's on a stock 10 bolt with a transgo and it shifts really hard. So hard my trans is starting to go O well its time for a TH400
