I'll be ordering my PCMforless tune in a few days & need some input on the shift firmness. I've looked thru the site & they're seems to be alot of discussion about firmness 1 & 2, but little about level 3.

For the guys that have level 3, how are the shifts during normal around town driving? I like a hard shifting tranny, but if level 3 is so hard that it's pinging the U joints everytime it hits, I might want to go with level 2.

I've installed Vette servos in 4L60E's in the past & wasn't real thrilled with the results. I'm use to old school shift kits, leaving out some check balls, that sort of stuff.

Like I said, I want it to chirp going into 2nd at WOT, but dont want it busting u joints every 10k miles. Honestly I don't think you could make a 4L60E shift "too hard" without doing some internal work.

What do you guys think?

I have level 2. I wish I had level 3 although I have no experience with level 3 and whether or not its "too much".

Thanks for the reply pittdawg, Im all for hard shifts when I have it stompped to the floor, but I don't want it beating the crap out of the driveshaft, u joints & everything else while im driving around town. But like I said, I dont think it can do that just from a tune.

On a different note, how a do you like the 4:10's ? I'm not a fan of 3:42's in a performance application. I bet these rigs would do much better off the line with some lower gears.

I have the shift firmness 2, and its pretty strong in my opinion. I have had my tune for about a month now and I still feel like I get whip lash when I drive it lol. I do 95% city driving.

Had 2 now have 3. Not much different but 3 is just enough more solid I think you should get it.

I would get 3 every time now that I experienced both.

I don't think you can get tire chirping performance without a shift kit.
Transgo and B&M both make them:twocents: I believe all they do to change shift firmne.ss is increase the line pressure.

Cool beans :thumbsup:

Looks like I'll be going with level 3. I agree with Mypetropig, I don't think you could ever make it too hard without internal work. I'm looking forward to it, this thing has had, in my opinion, a slush box tranny from day one.

It'll be after the holidays before I can send it off, but I'll let you guys know how it is. I'll throw up a vid also.

I got 2 but feel its a bit too much but then again don't have a setup as big as the guys! I'm hoping with the bigger tires end of the month it won't jerk as much when shifting :wink:

All goes down on your taste buddy!

Since you have the servo installed, go with the level 3 if you want the most out of it. With me, shift from 1-2 is amazing. It's solid and makes your head jerk back a little bit.

On the down side though; once you cold start and driving down the road getting it to operational temp going 10mph@1500rpm in first gear, it will shift hard not knowing if it will put more wear on the tranny. But if you keep the fluid clean, you're in the clear.
