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

Because there are very few "real" experts here. Certainly none have appeared in this thread. I threw out what I know and have been experienced with better than 25 years, and as usual got shot down by one of the forum "geniuses". That's when I backed out of this thread.

Fact is, release time is crucial to how fast a Torqueflite shifts, but I will be damned if I will ever make that statement here again. Too many people wanting to puff up their chest and make the other guy out wrong.

Too many people take for granted that if you don't "know something and know it "their" way" that you're wrong.

Remember, Ford calls one thing by one name and Chrysler and everybody else calls it something else. Too many people here think their way is the highway. Makes me want to punch their fuckin teeth out.

Yes , I think release time is critical as well, Mopar had a bunch of different servo spring pressures as well as clutch spring numbers and leaver ratios.
I chose to talk about the cup first on purpose, because it is designed to cover up a lot of variables in the transmission, as well as a lot of trans variations over the years, and how can you do that unless it's by compromise???
By setting up the correct spring combinations and clearances I believe that you could do away with it, or at least not have such a narrow restriction.
It looks to me that most people just rebuild the trans with the springs they have, whether they are HP or passenger car ones, tighten the packs and pop in the plug because they are told to do it.
I think there has already been some good info brought forward in this thread.
It should be noted that these kits are designed for an already assembled transmission and that's not what I'm talking about here.
