So I’ve tried to figure this out just looking around, and I’m going to clean my terminals before I drive again, but is their any chance that corrosion on the battery terminals could be the source of shifting delays? From what I gather my car does have an ECU but how much that effects the transmission I’m struggling to figure out. I’ve read that in cars with ECUs that manage shift timing terminal corrosion can cause low voltage that leads to the poor shift management from the ECU. I noticed the terminals were corroded when my car wouldn’t start this morning. I’ve had trouble rolling my windows up and down but thought it was the motors going bad. New to this car stuff. Appreciate any insight. Hope my transmission isn’t shot 🤞

 

The 97 has much more "electronic" transmission input so low voltage could play a role. Clean your battery terminals and charge your battery and the test drive and see.

What I don't know just off the top of my head is just how much more the TCM (transmission control module) does in the 97 vs the previous generation of civics (the ones I know more about).
