I just brought my 99 tahoe to the shop to fix the spider injectors. I was having the typical evap misfire, got it fixed hesitation went away. But now the tranny feels odd when I'm going from 40-75. When I push on the pedal going uphill I feel a little kick, but more of a normal one. Then as I let off the gas it jerks as if it's kinda downshifting. Hard to explain hoping for some answers. Thanks
