STage 2 or Stage 3 Transgo shift kit????

[jaynutz]

I have a quick question i have a stall converter and i am going to install a stage 3 shift kit. A friend of mine wants to know what will happen if he installs a stage 3 without a converter???

[DominusEtDeusNatus]

Stage 3 is really not needed. It helps nothing. You will not get better ETs, you will only raise the trans pressure. Why would you want to shift like a Mac truck? You do need some overlap of gears unless you have your whole tranny build, which you don't. I drove a car with a Yank converter and it had no shift kit. It was even on a V6. Shifted just fine. This whole shift kit business is very over hyped.

[jaynutz]

i have figured that a shift kit doesn't make u goi faster but i have noticed that quicker shifts give a better overall performance.

[DominusEtDeusNatus]

If it doesn't make you go faster how has the performance increased?

[jmorgan]

when yank recomends NOT to use a shift kit I think ill listen to them

they know a little more then I do and they wouldnt of said it for no reason

all it does is ad strain to your trans

Care to elaborate Dom.. Fill us in as to why you now believe the shift kit is a bad idea by which it hurts the transmission when a year ago you believed it to be a good idea.

Inform us oh wise one.

How does it do the damage? Why is it that so many people think shift kits ARE a good idea and prolong transmission longetivity?

when yank says this

<blockquote>quote:</font><hr> Is a shift kit required or recommended?

Yank Performance Converters can achieve maximum performance and efficiency without the use of shift kits. Shift kits dramatically raise transmission line pressure to increase shift firmness. Increased shift firmness will not increase performance, but create unnecessary stress on the transmission and other drive-line components

i think they know what they are talkin about considering they rebuild transmission too

How is the PCM programming going buddy? In January you said "soon"

Your car shifts like a Mac truck. If you like that it's all good. I don't feel the need for it. I'm not going to recommend something cause you're using it. And just because you're using it doesn't make it a good mod.

When new information comes to me I take that into account. I'm not stubborn. I found a different way to make shifts firm. A better way. :cool:

You like to listen to the majority. I like to listen to the ones that actually know what their saying. How many of those people that told you shift kits are good actually have done performance rebuilds? Zero? That's what I though.

Does FLP use TransGo shift kits? Nope, they use their own designed parts to make shifts firmer.

I talked to guys who designed high performance parts that are in alot of transmissions. I don't just read ads. To each his own man. [img]smile.gif[/img]

You already have a Trans Go installed my Speedinc. I doubt you'll pay again to take it out so why do you want to know this? [img]smile.gif[/img]

Or are you just trying to be a smartass? [img]smile.gif[/img] :cool:

Chillax *******. j/k, but seriousely my post wasn't meant as an attack.

Your special price is $350.

Now that my MAF readings are recalibrated my line pressure had descreased a ton and the tranny shifts normal again.

I never claimed it was a good mod just because I use it. I was constantly telling people in the drag racing section there are better ways to invest $$$. I do feel it is needed with a bigger stall converter though.

Please elaborate.. This is the whole point of my reply. I would like to LEARN from the masta himself. Teach me oh wise one. *bows*

Not the majority, I like to listen to factual information told by those who have done the research (YOU).

Such as?

All I got out of my phone conversation with FLP is that they definitely don't use TransGo. They didn't say straight out but accidently told me in another way. I asked them how much for a shift kit. They said extra $200. So I'm like "why so expensive?". They said cause they go into the inside of the tranny not just the valve body. Trans Go is all in the valve body.

Billet indermiediate servo will give a firm 1-2 and 2-3. Billet overdrive servo will give a firm 3-4. But you can't just put those in as they are too strong for some components. They will rip the stock band apart. Same for Kevlar. They only one that will hold is a red lined wide Alto band. Anchors are too weak on the stock one and the Kevlar one. There is the irregular fluid pressure above 5K. Lot of valves need to be replaced with oversized versions to prevent leak back. Some springs in the pump. Tons of little stuff. Lot of stuff that is stock on 97+ like 13 vanes instead of 10 like I have. There isn't that many working parts in there so paying over $1K for a bulletproof rebuild is a rip off.

[Magnus]

Cool.

Can you explain a little on how the valve body and servo's differ in the way they increase pressure/firmer shifts?

I take it the correct way is via servo's and not the valve body, but why?

[NBMA4V6]

i say if you spray nitrous on a stock transmisison a shift kit is necessary...when one of my frieds was sprayin his car it would not shift fast enough and would hit the rev limiter and then after the shift kit his problem was solved..never has the problem again..

with a stall converter i plan on doing shift kit at the softest setting..

They both need to be addressed in one way or another. There is weak points everythign. Everything there leaks fluid or has weak springs. Let's face it, our cars have many corners cut to keep cost down.

Trans go is ok to use with a complete overhaul, but if you're doing complete overhaul you don't need it then. They just increase the fluid pressure and fix a few things like a larger valve in a place or two. With servos you have the same pressure but more area applying that pressure. Better frictions can take the abuse, stock ones will not be happy. Alot of places where the fluid leaks back now leaks back more since you just increased the pressure. If you have oversized valves then its less of a problem, since nothing leaks back but people just put shift kits and nothing else in there.


You have poor line rise, which can result in 3-4 clutch, 2-4 band failure or poor shift quality. The duty cycle of the EPC solenoid causes the boost sleeve to wear quickly. Oil enters the torque signal orifice, leaks past the boost valve, and exhausts through the reverse orifice, resulting in poor line rise. Reverse oil can exhaust both to the sump and back through the torque signal orifice. The outside diameter of the boost sleeve also allows some leakage through the pump body, which decreases pressure rise.

3-4 clutch pack is addressed in almost all rebuilds. Not just the clutch pack itself but things related to it like throttle boost oil leakage. Same for the 2-4 band. Kevlar does not have the coefficient of friction (holding power) that other materials have that are now in use. They lack holding power and are known to destroy the reverse/input drum. So I go with wide red lined Alto bands.

Trans go has the large boost valve and that's a good thing.

There is a mis-match in the accumulation area on the 1-2 shift part throttle shifts. This is due to to little accumulation.

"I do not think that just installing the Shift kit will fix everything, there is much more to it than that" Gil Younger (Founder of TransGo)

Replace or install or remove
-"High RPM" pump slide spring
-.500" boost valve
-billet servos with alto band only
-Good clutches, your choice, blue might be overkill, tan at minimum
-Throw away the "load release" springs out of the 3-4 clutch pack
-"hardened" sun shell
-clutch regulator kit
-I'll probably go with #72 selective input washer
-I haven't decided on input sprag type, either 29 or 34 element
-I haven't decided on the number of frictions or the thickness or whether to mix and match
-kolene steels
-front and rear 5 pinion planets
-new bushings
-13 vanes since I have 10, 97+ have 13 stock.
-check end play and band clearances
-alot of other small stuff

And don't forget that ALL the transmission builders are former brain surgeons AND rocket scientists. They are trained from childhood in rebuilding the transmissions by the masters of black art. That's why FLP transmission is so expensive. They are also vampires since it takes 500 years to learn how to do it right. Alright I'm out, going to add ZMAX to the car and adjust the tornado thingy to max boost.
