Hey bud! moved your post, I thought it was a good thing others might want to read on its own. Here's my question,

"Hit the rev limiter twice this a.m. trying to let the auto trans to upshift on its own. It's amazing, I'll be screaming right along and then whamo!, the RPMs drop and moms in minivans are passing me going uphill on Interstate 287 North (for the Jersey guys)."

(I was 287 north today)

When you say you hit the rev limiter, your saying that you floor it, the SC sings, and the Jeep is a rocket....But it dosent shift? And you lose the speed you built?
