Yea, the pressures in the tune have a lot to do with it...

 

ok ill have Wheatly send me a file

 

put my stock servo back in this morning no -help still a brick breaker at 1-2 shift didnt even make a differeance at all...got to be the tune pressures

 

The shim in the accumlator makes a huge difference..

 

If you have HP Tuners send me the file and I'll take a look at it. All my money is on your force motor current tables needing decreased.

I battled the identical thing as you...break-neck 1-2 shift no matter how many times i fooled with the shift pressures, etc.. Finally was able to DRAMATICALLY reduce the harshness in the Force Motor Current Tables.

 

man thats awful nice of you to offer ...it may be just that because its worse when you barly give it gas ...its better at 3/4 to half throttle ...kinda tells me the pressure is to high all the way around...I just have the HP software no cables anymore i was referring to Wheatly sending me his cables but iam not sure if the ECM is locked from his last tune...the guy is really good and certainly earned his tune fee with me...lol...kinda waiting to hear back from him...its just the waiting for the mail each time i send it off kills me because this is my daily driver and I am a very impatent person...<(still working on that)...but yea if i locate some cables I will hit you up on that if i need too and thanks again for youre offer...

 

You need to find out what he drilled the spacer plate too also. I have a feeling thats your problem.

 

thats what my built one did it chirped 33's nearly every 1-2 shift till the trans broke

 

How much??LOL J/K
Reducing (Number values) force motor current will increase firmness

 

Then what the hell is wrong with my trans? I reduced them a bit and it shifts perfect now.
