Customer Question

2002 cadalac deville engine light came on, service transmission light comes on, and indicator on what gear I am in doesn't show up on display. What is going on?
JA: I'm good. And you?
Customer: I typed in my problem. Can you help?
JA: Sorry to hear it. Have you checked the transmission fluid?
Customer: I will but doesn't it have to be a warm engine to check that fluid?
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Just replaced the starter. Hoped this was a minor issue and I could fix it myself. I also just put in a new battery.
JA: Anything else you think the mechanic should know?

Hello, my name is***** would point toward a problem with the transmission range switch which tells computer what gear you are in. This is about a $500 at shop depending on where you go, switch is located inside transmission. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
