Can I put the gear ratios from the Z06 in my T-56?

VINCE · 11-12-2001, 11:33 PM

I was wondering about this.. Looks like the Z06 has some awesome pickup with the first 3 gear ratios being shorter. How much would it cost..?

Im thinking a lot. You'd be FAR better off financially buying a good 12-bolt with 4.10's. i remember Patman saying he still saw 28-30mpg on the highway with 4.10's. He had a pretty stock LS1, but I think you'd see upwards of 25 or 26.

You do not think is would be worth it? I do not think it would cost as much as a 12 bolt to put Z06 gear ratios in..

RyanJ · 11-13-2001, 12:16 AM

i definately think it would be worth it. I would call around to reputible shops like D&D and Westech and see how much they think it would be. Never know. Just seems more simple to throw in a bad ass clutch and rear and pull the wheels <img src="images/icons/smile.gif" border="0"> <img src="images/icons/smile.gif" border="0">

From what I have been told, it is not a direct swap. You would need to replace the input shaft ($$$) and other things. Maybe someone else could find out exactly what else.

http://www.ttcautomotive.com/ This site is where I checked the #'s.. I called a place today and they told me they will get back with me on the parts.. They have 3 packages for our cars.. I am surprised no one has done this.. Just look under T-56

It's a nice sounding idea, but if you want the extra gearing I think you would be better off going with 4.56's or so. I am 99% sure it's not any type of direct swap on the gears - primarily due to the difference in input shafts (because the C5 is transaxle).

I will know soon.. I will keep you guys posted..

LEO · 11-13-2001, 10:31 AM

Damn Vince you and I think a lot alike! A couple of months ago when I blew my tranny, I was thinking the same thing - I looked into it and it seems really expensive and it isn't a direct swap.

VINCE · 11-13-2001, 10:46 AM

Looks like we do think a like. I know the Z06 tranny itself is not a direct swap, but the ratios should be. If you click on the link I put in the post. You will see we have 3 gear ratio options. The C option would be crazy quick, but I put it in the gear calculator and you would run through 1st thru 3rd in no time, but 4th would be like stock. The rest of the gears would be awesome as well.. I will let you guys know when the parts place call me back..

It's all about the 60'. I think a nice steep 1st gear, and some 4.56's would be bad ass!

Louis · 11-13-2001, 02:22 PM

The early LT1 1LE cars from the factory had a stump puller of a 1st gear. used them because when a 5" clutch is used, it is hard to take off, it was in the 3s, i think 3.07 tobe exact, but dont quote me on that.

That was 93 only I believe. 5th, and 6th gears were differant than 94-up. The LT1 uses a different bell housing than the LS1 though (I think).

HI there,
Yes, this change has been done, and yes, the gears and syncros are a direct swap.
As for the other issues, remember that the ZO6 trans, coded M12, carries a heavier inputshaft, as does all Corvette stick shifts. Stronger than the f car input shafts.

How much did it cost to do it? I have not heard back from the shop yet..

c4c5specialist · 11-14-2001, 05:58 AM

HIthere,
For everything, parts about $23oo, and the labor about $6oo.
Besttoyou, c4c5

Wow... That is up there...

Seems on parr with the cost of a new T56, my question is: Were all the gears replaced (the 0.50:1 6th is quite anemic IMHO) and WHO did the conversion?

Also, any idea if the syncros can be upgraded? (Seems to run in my mind that some of the older style T56's could be had with brass?) Doesn't the M12 use carbon fibre? (Which would also be a nice step up?)

TIA,

- Joe

HI there,
I do all the work, on all the performance cars that enter the dealership, and I did all the work personally. I serve every part of every car, I demand this from my dealership, as if my name is on it, I do the work.
The brass versus ceramic composition is an incorrect comparison, given that the blocker rings are what you are speaking, not the actual inner and outer cones, which is what was changed.
On t-56, blocker ring durability is what is at issue, and the revised inner and outer cones are the major changes, and these are direct swaps for the revised parts.
Any good shop who knows what he is looking at in regards to T-56 should be able to perform this correctly. Now, if they WANT to do this, thats a different story.
Besttoyou, c4c5
