Tuning VS shift kit
well im fixing to get my yank ss4000 and im going to get it tuned to really make the whole car come alive, but what i was wondering is should i buy a shift kit, or just see how good the tune turns out first? see i would like some pretty firm shifts. esp from 2-3. just wondering if tuning will do the trick or if buying a shift as well will make it better.

tune +shift kit
Tune + shift kit,you wont be happy just tuning,tune will firm it up ,but if you want a short ,solid shift(breaking tires loose at wot 1-2 ) tune + transgo,and take your 2-3 feed hole to .101,I went .110 with mine ,but if you have alot of wear on the trans it could be hard on it,but unless you want a mushy 2-3,thats the only way you will get a good shift,I just went through all this stuff,but do it right the first time,and then its done.

I got a shift kit for my car but never put the thing in.
I have the same stall and stock gears and went 12.24 last night at the track. I tuned it myself and dont hardly know anything about it just started tuning things till I got it to that point. If you have a good tuner I would let him get it set up and see what you want to do then.

I had the transgo shift kit in my 60E with a Fuddle 4k stall. It made nice crisp, firm shifts that would bark the tires from 1-2 at WOT. When I did my 80E swap with a Yank 3600 stall I left the shift kit out (I bought it for the swap) to make sure everything worked right mechanically and tune-wise first. The tuner increased the line pressure, etc., but it doesn't make up for the mechanical parts that are changed doing the shift kit. I plan on putting the kit in and backing down the tuning changes next weekend. Tuning can't take the place of the actual mechanical changes a shift kit does and it makes a difference. Trust me, otherwise, I would be selling the kit instead of crawling back under the car.

That being said, there are certain things that can only be done by tuning: changing shift points, shortening shift times, lock-up/unlock points, etc. You will want adjust all of these to complement your converter's characteristics.
For the best of all worlds you really need both.

i bought a trans-go kit when i purchased my converter. after talking with the local trans shops they were pretty universal about not wanting to take apart a 100K trans without "freshening." My tuner runs a stall in his auto so he said the programming would get it done. he deleted TQ management and firmed the shifts. That being said if i ever get a rebuilt trans i would have the trans-go kit put in for sure, but for now the tuning has made a huge improvement in shift feel.
