That will not achieve anything if the factory spring is in there. Clifftt is supposing that the spring-retainer is touching, rubbing, or otherwise interfering with the reverse lever action. Even without a gasket this is not supposed to happen. But the possibility still exists, and so it's valid help. The only issue I could suspect with a non-stock spring is coil-bind, but with the length of that spring I can't even imagine that situation. As to the power of that spring, the mechanical advantage of the stick makes that rather moot. As for myself, I rather like a good stiff spring in there..... and I have a pretty short stick, stock-length Mr.Gasket Bang! shifter. I like it for two reasons; 1) it makes darn near impossible to accidently put it into reverse, and 2) it makes this really great sound when it goes in.
