The people that would really benefit from this transmission are the people that already have an 18 spline box in the car now.There are so many guys out there with 4.10 gears in the rear that don't like to drive long distance because of cooling problems and or fuel consumption issues.Enter the Passon 5-speed now you can stab this tranny in your HEMI GTX with a 4.10 Dana and drive it ANYWHERE! All you guys whining about transmission cost obviously haven't priced a "strong" gearbox that will take an extreme beating and still come back for more. I put a Richmond in my car because there wasn't an option like this available at the time I have over $3000 in the trans and all the stuff to make it work in my car with some extensive modifications to my torsion bar crossmember all of which all could have been avoided with this wonderful tranny Now if I could only sell my Richmond to buy this new box Thanks for all of your hard work and dedication to bring your vision to to life Gus
