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.

I think I may not have made the reason for this thread clear. It's not about if you should have a shift kit, it's more about if you really need to use all the parts and do all the mods that the kit asks you do to, when you are building a trans from scratch.
The first part I'm looking at is the cup plug and it looks like if you were to use the correct selection of parts and clearances at build time then this plug would not be necessary..
It's easy to say.. " oh yeah, just stick a shift kit in it" but how many people really know exactly why they are doing these things.

As I said, so far, there are two parts I would use in the kit. That's the
New manual valve and the stiffer line pressure spring.
I'd like to discuss the rest of the parts and why we would use them..
I think it's a good topic and would give a different perspective on trans building..
