07 Denali "hunts" and slow Tranny shift ....

[boomer 33]

Does anyone know if there is a computer update to make the the Tranny downshift earlier after making a turn????? Too slow when you give it the gas after a turn and then after you give it a lot of gas pedal it downshifts and picks up again.

Anyone else aggravated with this?

The only way to get the trans to shift faster is to reprogram the PCM. Gm has no trans updates for slow shift.
