Shifty Kit in GEN3

[G4orce]

Hey guys today I made some phone calls as to getting a shift kit fitted to my car. I was givin different prices from everywhere but one place told me I need to get The "torque reduction program" removed. Now I have never heard of this and it is going to cost me $350 on top of the shift kit. apparently you need to do this to all gen 3 cars or you will lose power or get the reverse effect to what you are paying for.

Now has anyone else heard of this or are they trying to take me for a ride?

I've heard of getting rid of the torque reduction - tuners usually do it as part of an edit tune or mail order tune. Basically they get rid of the factory torque reduction which gives you more torque off the mark but also makes it even easier to light up the rear wheels.

...As for doing it as part of a shift kit installation - I'm not sure - be interesting to find out.

its called torque management its stops you from spinning the wheels
you dont need a shift kit a tuner can firm up your shifts
just get a tune and the tuner will sort it for you

Yeah i thought a tune would fix it but the guy I talked to tried to twell me a tune wont do it, I think he was trying to take me for a ride with the $350. I know that a tune can give you better shifts but from my experience in my past cars a tune is not as good as a shift kit.

speak to someone like oztrack he can do you a mail order tune for $400-450
and he can make the shifts as firm as you want

yeh with the gen3's u can change the shift pattern electronicaly so you don't need a shift kit, iv had a breif look at this with efi live on a performance course i did at tradeschool, and as stated b4 when the tuners do the tune they ussualy change the shift patterns to suit your set up or to suit you so like haveing a shift kit and u kill 2 birds with one stone so to speak, iv had heaps of ppl tell me to drill out my valve body to make it like a shift kit, but y bother when it can all be done electronically when tuned. save ur $350 and put it towards a good tune and get them to suit up the shift patterns for you what u want, or like said speak to oztrack or brad(enhanced) bout there mail order tunes to suit your vehicle, and the shift pattern changes or depending where you are going into see them, good luck with it.

Its the same as the electronic shiftkits.

Its a cheap and nasty way out

You're increasing the line pressure in the transmission, putting stock internals under increased pressure that they are not designed for and you're not upgrading ANY of the parts.

Do it once, do it right and get a proper shiftkit. A proper shiftkit will make a much nicer difference, give you firmer shifts, increase the strength, durability and lifespan of your transmission. What you are suggesting will decrease the strength, durability and lifespan of your transmission.

For a few hundred $$$ I know what i'd be doing (well, what I did).

dont think so
how is a shift kit going to make the to stronger?
all they do is let the box flow more fluid which is the same as upping the kine pressure
there are guys out there who have ran hundreds of passes with stock box's
and i have not heard of any putting shift kits into LS1's before
yeah the box's arnt very strong ,but to make them stronger you have to get them build

Bummer, Now i am confused lol. I have not owned a gen3 before but like i said in my experiences with cars(vp-vs) a shift kit did a lot better then a tune. I understand that the gen 3 are very different and after reading through the replys it seems a tune would be the best way to go but people are all telling me different things, I have been told a shift kit is the best way to go by some and a tune is better by others. So Now I have no idea what to do.

Have a look here.How about a transmission tuning tutorial! - Page 2 - EFILive Forum
It might answer a few questions for you.
Personally I would go with the tune. A shift kit wont do half of what a tune will.

You would get a tune as well. I wouldnt get a tune just to change shift points.

Not sure if you realise this but a shiftkit has parts... Also, I GUARANTEE you that you won't get the shifts anywhere near as firm in a tune as you will from a real shiftkit.

With a shiftkit you'll be able to hold 1st, 2nd, & 3rd to any RPM. You will also be able to downshift at any RPM or just drive it like a normal auto.

This is what the transgo kit does:
"Corrects/Prevents/Reduces: FIXES Code 1870 Trouble light & Hard 1-2 shift. Fixes sticking TV Valve. Fixes 3-4 clutch failure. No lockup or 4th. High pressure parts breakage. Fixes harmonic bounce that wears out pump and valves and causes shuttle shifts. Fwd and L/R clutch burnup; 1-2 bump; double bump; slide-bump. Has new design Isolator/Conv Valve"


What is one of the most common cause of damage and wear in automatic transmissions? Slippage! Especially in high powered/modified vehicles. A shiftkit stops this much better than a tune. You should also get a corvette servo (if not billet in an LS1) to help reduce slippage even further.

The valves etc. that have to take the brunt of the increased line pressure as well as springs etc. are replaced with a shiftkit. The transgo kit uses a .490" TV boost valve for the 4L60e (VS onwards). You're not just upping the line pressure on stock parts/valves/springs.
