Any update on this? We’re you able to get this resolved?
After the battery change, hard shifting and getting stuck above 2nd gear came back today. Didn't throw a code but this is what it does before it throws the code. It suddenly went into 3rd gear then fell back into 1st and hesitated to go into 2nd with the RPM’s going up and down between 1st and 2nd & the car responded by going back and forth until finally kicking into 2nd. When I get in 2nd and start slowing down, it takes considerably longer to shift down and the speedometer needle stays in the same place while it’s waiting to downshift.
