Thanks Guys, I'm trying to make a Saturday night tune appointment. I'll post the chart in this thread when she gets it.

 

Update, The tune is on for tonight!

Current Tune Pictured Below.

 

I was told barking the tires was actually better than shifting really hard without spinning because when you spin a little it relieves the pressure on the tranny, differential, axles, etc. Mine barks going into second almost every time especially if I use the tow/haul button as I have it setup for the track so that it shifts even harder.

 

I would say 75% of my shift firmness comes from the shift kit. The builder has many options with orfice drilling and springs. My sonnax kit did. You also can turn the PC solenoid torx screw in about 1/8 turn to raise pressure. You can take out 75% torque management without issues except punching it for a 3-2 downshift. That is the fastest way to break the trans. Just be sensible driving. Going from a dig with you app. should be fine. You can command the pcm to do things but if the pressure is not there is makes no difference.

 

I can't see how that makes any sense. If your not applying enough shift pressure to bark the tires, then your not causing any strain on the transmission.
If your barking the tires, your jolting into gear for no reason and that creates tension.

 

If you are not applying enough shift pressure then the slow shift allows the clutches and band to slip during the shift causing excessive wear and heat. Overheated ATF looses its properties which causes friction material to go bad and o-rings to go hard and leak. Over time this will kill a transmission.

You want it shift firm but not jerk you. As far as barking the tires, what I am saying is that the tires slipping puts less stress on the axles and driveline than not spinning. Try breaking an axle with street tires and you will probably spin before you break anything but slap on some slicks and you might break something.

i recently went to the track and was to lazy to remove the DR's so I drove around with them on for a week and it would shift harshly without a bark and that is bad for my hard parts. With the street tires it shifts just as hard but barks the tires a little so that relieves stress on the drivetrain.

I am not saying make it as hard as possible just that the factory settings are to soft.

 

Yes the tire barking is better than it not barking and needing to. But you shouldn't have the pressure high enough for it to Need to bark them. The shift pressure doesn't have to be to the point that the tires have to bark to keep stress down. The Servos' will apply sufficient pressure to ensure a solid shift.

I understand completely what your saying. but you don't need the pressure high enough to make the tires bark. If your tires bark, just back off the pressure a little cuz thats too hard. If its hard enough to bark em, its hard enough to break something.

I had mine barking for a while, but decided to back it off so I don't break anything.

 

I'm with you 100%.

Mine shifts that hard because my tranny is built. I actually have the stock pressure settings and zero shift times. In my "Performance" setting I have higher pressures though.

If I want my shifts to be less hard I would have to lower the pressures(less than stock) and/or add some tm. None of which I want to do as I like the way it barks, which is why I drive around with the tow/haul on, lol.

Actually, I will probably reduce the harshness under "Normal" mode just a tad at low throttle only.

 

Thanks Guys, I'm good to go. New Dyno numbers link in my sig.
