Did you already have the HX trans on hand?

I wasn't too worried about the car driving differently. I knew it'd tach lower at highway speeds so that was my main concern with the swap.
When I purchased the car the prior owner gave me the stock HX trans and some other stock parts. The first time I took it out I realized it revved very high: With the SI trans it was around 3500 RPM at 65 MPH. With the stock HX trans it went down to 2900 RPM at 65 MPH.
After running through my first full tank with the HX trans I was very, very happy with the results and the FE boost. Looking forward to even better FE in the future.
