i just installed an edge evo cts programmer. i first loaded level 1 trans only mods and took it for a spin. then i came back played around with some things and decided level 2 would be better. i loaded level 2 and adjusted a few of the parameters. the parameters i changed where trans shift firmness. i increased them all by 10%. went out and test drove the truck. on both trans only mods wich i left canned and level 2 where i bumped up the shift firmness i can hear a noise similar to gear whine or really low tire noise. this was not present before the programming, at least i did not notice it. is this noise normal after programming or is it something i should worry about? truck is an 06 150 4x4 5.4 flex with 160k on the clock.

 

you mean when its moving or as its writing the tune to the truck?

 

when its moving. i have driven the truck more since the last programming and it seems quieter to the point its nearly imperciptable. maybe it was things settling.

i just got the truck a few days ago so im in the process of going through everything. trans service is on the list and not too far from the top.
