94 530iA transmission issues
Two days ago I noticed that I had full power when I tried to pass on the freeway going around 55 mph. No hesitation, nothing. It just surged forward. It was a thrill. Then, once I calmed down and settled at speed, I noticed my RPMs were high. It usually settles around 2000 RPMs cruising at 70 or more. It just has never worked hard while at a cruising speed. Now, I notice that it can be at 3500 or 4000 going 65mph. That's crazy and this is going to ruin my already abismal MPG. I assume it's because my car isn't downshifting. What would cause this? ECU issue? Transmission failing (automatic)?
Help? I love this car and want it to live!
