Interesting!
So it removes the reverse lockout solenoid and replaces it with a spring detent pin that should require some additional force to shift into reverse compared to shifting into 5th, but not as much as forcing through the solenoid?
Definitely curious about how well that works. 5th isn't exactly a "power shift" kind of gear so a little extra tension should be sufficient to keep you out of reverse, or at least give you an indication you missed the shift before you drop the clutch and go into reverse.
Well that's lame. Although to be honest those warranties aren't worth much in applications like this. It's too easy for the manufacturer to say "well you installed it wrong" and wash their hands of it. Unless it's insanely obvious is was a manufacturing defect I pretty much figure I'm SOL, especially doing my own work. It's a little easier to get the warranty coverage when you can point to a "professional shop" for the install work.
