I have REDICULOUS news. Turns out that I probably got an HX/CX transmission. I never took the time to verify the final drive ratio and after I started the job I realized I should have. However I had what I thought was good intel on the transmission as an EX coupe which should be 4.250. Overall regression but what can you do. Well I took my car on a quick 130 mile highway round trip on Saturday and the RPMs were significantly lower. I wasn't hitting 3000 RPMs until I was getting close to 80 mph. I made a spreadsheet on my car's gear ratios a while back and before 80 mph was 3483. Now it's supposed to be 3194 which jives with what I saw on the scangauge. I'll have to start data collection to verify vehicle speed and try to deduce the ratio and come to an independent conclusion but this just makes the outcome that much better.
