A little update...
I've got the VX transmission ready to install in the car. I opened up the transmission and resealed the casings together with RTV. I could tell that it was leaking fluid from how dirty and oily it was in a certain area. I also installed new axle seals, and cleaned up the transmission a lot.
I've also been underestimating my fuel economy in the logs, by a pretty large amount. I've got tires that are about 1 inch larger diameter than the stock configuration. This setup made my speedometer read dead on, GPS verified. I know most cars actually read slower anyway from the factory, so I figured the larger diameter tires corrected that. Well tonight I measured out my 50 mile commute home, accounting for elevation changes. It came out to 49.9 miles. My ODO read 47.5 miles. 2.4 miles difference is 5%! If you look at my current highest tank of about 46 MPG and apply the correct miles traveled, it brings it up past 48 MPG!!!
I'm going to calibrate the ScanGauge with the correction, and use SG data for calculations from now on. I've got a GPS unit I could try too, just another way to make sure my calculations are accurate.
