I just bought a 2006 Chevy HHR 2.2 4 cylinder with 186,000miles. I purchased this vehicle to solely use for Uber and Lyft driving. Had it a couple weeks and every once in a while like maybe once or twice a week I notice something when taking from park to drive or reverse to drive . The car is always warmed up but when I put it in drive then go to accelerate the rpms go up and the vehicle is barely moving or not moving. It only happens once or twice a week. When it happens I put it back in park wait a moment, shift to drive wait another moment and I’m on my way. Sometimes it will happen just a couple times in. A day then it won’t happen anymore. Since then I always wait a moment when putting in drive until I feel the transmission shift gears and I haven’t really noticed it since besides one other accurance. Any ideas? Hope it’s nothing major.

 

 

Could it be low on trans fluid?

 

If there are no DTCs then trans fluid.

I guess it could be a torque converter.

 

I would first look at trans fluid level. You have a lag between gears. Are there any signs of leaks ?
The next thing to do is drop the trans pan and see if it's clean or not. Seeing material is a sign of friction clutches are worn.
While it's down look at the filter too. A restricted filter can cause the lag also. But if it's dirty/clogged something clogged it material wise.
