2007 feels weak in overdrive on hills, vibration in overdrive
I have had my transmission replaced by a warranty company in my 2007 tahoe ltz. It was good for a while but now feels extremely sluggish on hills particularly in high gear or overdrive. It also has a vibration in overdrive under 40mph once above it is not noticible. Could this be the torque converter? Also when running in overdrive if i ever so slightly press the gas the vehicle kicks back down to third, like it wont pull hardly any in overdrive. Is this just because gearing is high.

the vibration could be the driveshaft out of balance, could be a wheel out of balance...
with it being a 07 I wouldn't be suprised if the trans is programmed sluggish for mpg...

Have you had the vehicle inspected for this issue? If you would like, PM me the last 8-digits of your VIN and I will check my resources for any known issue.
I look forward to your reply.

At that speed in hilly areas, you should push the button and stay out of overdrive.
We have a lot of 45 MPH here and alway s keep it out of O.D.
Its just lugging at that speed.
This is on an 2007 Tahoe.
