SCT Xcal 2

[Nocturnall]

So I have an xcal 2, programed the comp, I like how it runs but the trans makes a loud clunk often when going slower and it's shifting. Returned to stock and the noise went away. I'd like to avoid the noise and feeling if I can, I was wondering if I reprogram but lower the shift pressure would that get rid of the clunk/thud? Also is it possible for me to lower it too much to the point that it'll hurt the trans?

I would lower the pressure in the gear it is doing it in to remove the hard shift. You should be ok.

+1 - Reload the tune and use the User Controls to lower the shift pressure 10% at a time until it stops. Let your dealer know what happened and how much you lowered the pressure to make it go away.

I lowered all the gears 10% seems to be better. I am really questioning how well of a rebuild was done on my trans.

Just let your dealer know so he can shoot over a tunefile(s) reflecting the changes.-j
