Still hitting rev limiter at WOT
Well the tranny came in earlier this week and I finished putting it in a couple nights ago, and it drove/shifted perfect, with the exception of it still hitting the rev limiter at WOT just before it shifts. I would like to think its just a tuning issue. Becauase I know that there is a delay from shift command to the actual shift taking place. But what doesn`t make sense is that it has been shifting fine for the year that i`ve owned it, including drag racing last fall. I haven`t changed the gear ratio or done anything major like that to the truck, since then.
Any ideas?

Looks like I`ll be tuning it. I bought HP tuners last year and chickened out and sold it before I learned to use it. So I just ordered HP again yesterday and will start trying to learn how to use it when it comes in this week.
