When you guys say it helps shifting firmness, meaning it shifts smoother or it kicks a little when it shifts?

It should shift firmer/quicker/harder....less slipping, more force on the clutches, so it would be "less comfortable" of a slip.

lol sorry meant "less comfortable" of a SHIFT.....no it would be less smooth....but this is better for the transmission (less slipping)....the slipping makes it feel smoother.

well I like a firm shift, most "regular" or non performance oriented people don't like firm/jerky shifts and that's why manufacturers make them "smoother". A firmer shift that is jerkier with less slipping is better for the trans (and makes the truck faster slightly)

Nope! I want it shift so hard the tires chirp...even at moderate throttle....but that's just me.

I've owned trucks since they were still a truck. There weren't any fancy frills, just the basics to do 'truck work'. Most people didn't want them...because they were a 'truck'. Although I certainly enjoy all the great creature comforts of my new trucks, I often wish they were built more like a truck than a car. Fine, have all the fancy options, but make it a truck with options, rather than a car with a truck facade.

I so feel a rant coming on.......

I thought it was actually called a 65rfe...but anyway...

It's the same transmission basically, just different computer programming, but I don't think there's one for that transmission yet, I'd assume one would be out soon though as it'll basically be the same product with minor changes....if any at all...
