Shift kits.. do you really need one????

I'm go and make this one short as these are the facts to why you want one.

TrAnsmissions love to shift harder and quicker. Not abusively hard. They like it better, live longer since there less time the internals are creating less friction and heat which they don't like for long life. It also quickens the car in acceleration. All for cheap!

Add a cooler and a deep pan and it'll live a Long happy life shifting quicker and cooler.
This is why you want one.
