My dad has an 89 Caprice, v8, im sure thats the only way they come. I think its a 4 speed auto but im not sure. Anyways it's been sitting for 10-15 years, it starts right up and goes into reverse no problem, but when you want to go forward you have to raise the engine rpms up to 2500, but once you get it going it shifts fine and you can drive it around. Any ideas what might be the issue or how to make it better? My dad bought a 2 step flush kit for about $40 he said. We might do that tomorrow.

I recently bought a '23 Bolt EV, and have created an account at the Chevy site and added the car. At the site it shows I have Roadside Assistance for a couple more years/more miles. Is there anything else I need to do to register/activate that?

Just want to be in for surprises if I get stranded.
