2005 Impala transmission
Hey, new poster here.
I just bought a 2005 Impala on Saturday. Was driving yesterday and the transmission started shifting hard in all gears. Got home and let the car sit for a while, then drove to the store. No shifting problems.
Drove it today and the trans started shifting hard again. Took to a mechanic, but the trans shifted fine for him. There was a P1811 code, but no check engine light. The car has under 98,000 miles. He cleared the code and said if it happens again to bring it back.
I have to do something soon as I only have a 30-day 1,000-mile warranty.
Any help would be greatly appreciated.
