OK I had a CEL come on and the car started to run like ****



OK the o2 sensor is bad, easy fix. I found the pigtail to be smashed in between the starter and block, my mistake during the header install.



Car is running great, T56 input shaft said NO MORE!!!!! :banghead: Thank god for AAA.

Is it still under warranty?

Anything with a T56 isn't under warranty unless it's aftermarket or he bought some type of extended warranty.

Did the input shaft take out the diff too? I'd go ahead and upgrade both to a 6060. It's like butter compared any RPM built T56. I have a level 6 in my current car and would take my old stock 6060 over it any day. Good luck! Been there a few times.

no warranty

diff seems to be ok (for now until i pull it apart). with the car running and the clutch engaged i can go though the gears. i can also hear the clutch working and the driveshaft turning (poly couplers). so the problem lies either before or in the trans. i didnt hear any grinding, clunking of feal any jerkyness and nothing locked up. it just snapped and then freewheel. i heard the snap.

Tr6060 sucks

The smaller or narrow syncros make it worse to shift and less durable..

You can beat the dog **** out of a t56 for a while before you have any issues..

I have a tr6060 that I keep as a spare.

Hated it enough to put another t56 in my car...

If anyone has issues shifting a t56 it is likely the shifter assembly and not the actual trans..

Can't believe you broke that sucker..

Only reason I would ever do a tr6060 is if you actually just overpower the gear set in a t56.

Which is not what I think happen in this case..

I guess everybody is different. That's why there is a demand for 6060 swaps from a T56. Not many guys swapping their 6060s to T56's except Mile cars, but that's a personal preference I guess.

Deep subject

That sux Don. I'm sub'd to see what you find. I'm guessing it's a stub axle in the diff..if not that, it's the output shaft.

If it broke an axle, the trans will still shift fine and usually one drive wheel will turn if it's in the air, however it will not move the car. Posi needs load against both tires to apply the power. If one axle breaks, the other one will NOT get the power...it will only get enough power slipping thru the clutch pack to turn the tire in the air.

Same thing for the input and output shafts, the Trans will still shift fine, just no power coming in or going out the Trans.

If you hear driveshaft spinning in the TT, you know it's not the front input shaft or coupler.. it could be the rear coupler or input shaft in the trans but...

I'm betting axle.

Were you at the track when it broke?

I broke my "built" T56 twice. The second time it took out the 9310 G Force main shaft...but I think the diff failure is what broke the shaft, not the other way around.

TR6060s are leaps and bounds better then an upgraded T56. Bigger shafts, bigger gear sets, better cases, gear set oiling... Etc etc.

My T56 never shifted that great in my Vette.. Couldn't even think about power shifting it. However my T56 in my old Trans Am you could power shift effortlessly at 550 rwhp and never miss a beat. I think it's the goofy shifter and rod arrangements in the vette's torque tube that make them shift so notchy/clunky.

You nailed it. It's the c5 shifter that sucks..
The z06 t56 has a fluid pump and front mounted cooler.
The gear sets and case are different. But if you're not breaking gear sets or cases what good does it do??

Like I said above, unless you are over powering the t56 hard parts. It's not worth the up grade.

alot of money to be made selling used and new tr6060s

And it's a more common piece.

The z06 t56 was only used in 06-07
Compared to 08-14 for a tr6060. Not to mention they used the same trans in grand sports and z06 and you also have the zr1 option too.

They are just more plentiful and easier to get a hold of.

My point being, don't go through the trouble to try and put a tr6060 in your c6z if it came with a t56..

Yes there are differences but not enough to make it worth the trouble..

I had enough speed built up to coast to Gary Sr.'s house. they thought i missed a gear and i didnt. I just heard a "snap" nothing else, even afterwards when coasting about an 1/8 mile. 1st thing i did was to put it in every gear and nothing. Then i let the clutch out to hear if the clutch was engaging and drive shaft was turning in the TT and I could hear that. then with the clutch out and the engine running i was able to put it in every gear with ease including reverse, no grinding. then we jacked up the rear end and bill held one tire while i turned the other and he couldnt hold it, posi is still working diff seems to be ok. so be so we narrowed it down to the input shaft, i hope. Nothing in the trans is turning, but the drive shaft is. like i said earlier i only heard 1 "snap", no vibration, no grinding, nothing locked up or bucked, no fluid leaks, just 1 "snap"

winters97gt

now it doesn't suck? You're a confusing fellow on here.

The 6060 is a stronger, better shifting transmission.

Corvette problems. I'll pass. Buddy of mine swapping his 2000 C5 from auto to T56..... PITA.

why ....... i guess he didnt want to go fast

Because some people prefer a manual trans.
