Dude, that just sux !! You need to beef those tranny's up. I am currently having to change the pump in my 4L60.

The 29.5" tire is way too tall for your truck in my opinion. I run the 25.5" ET Street Radial as well as the 28" Hoosier slick on a 410 gear. My eighth mile is 7.0 on the small tires and 7.2 on the taller. ET was only a thousandth difference.

Sorry about your tranny.

I found a 4l80 out of an 03 with less then a 1,000 miles on it. Priced high, but its low milage.

Go with the 80e. The swap appears to be so easy on a 2wd.

I have a guy that works for LKQ, he gets me my parts at a very reasonable discount vs what they show on their web site. I guess havig a shop account with them since they have been around helps to.

How much timing are you seeing below 4000? If your setup is de-tuned for the spray and you aren't spraying at the bottom it could just be light on the timing.

Do you purge before using nitrous? It sounds like a good purge might help your shot hit on the first try.
