My Car Jerks Hard when Shifting.
A few months ago my car started doing this, just every once in a while.
This has now become an everyday problem.
So here is whats going on, when I shift my car from P-D or R-D it jerks and you can hear sort of a thud. When accelerating and shifting it is a hard shift and the car jerks forward. it seems to be the worst when shifting from 1-2.
The check engine light is not on.
One thing I have noticed is when the car is started cold it definitely will have this problem.
If the coolant warms up to at least 160 and I turn the car off and restart it, the problem is gone and my car shifts like normal.
I have a 2005 Cobalt base model. It is an automatic. 2.2 L
Thanks in advance for any input!
