Alright, then that means you have the better syncro set up, but the taller gears which some people have said they are not as strong(m12) and a 2 piece counter shaft. I dont have and personal experience with the m12 gears to tell you how much different they are but im sure someone on here can tell you. Now you can build up ur t56 with carbon fiber blockers(500$), and put in a different main shaft that is stronger. I used a 30-spline one i got from g-force(dont remember the cost). Then add a sprayer and a pump and you would definitely be well on your way. You can save some real money if you do it yourself and its honestly not that hard. I did a write up of a hybrid i built where i put c5 internals in a f-body/gto housing with a 30 spline hardened main shaft
you may be able to check the serial number on the tag. on the vette transmissions the shifter linkage is by the front plate so thats easy to rule out

Hey man thanks for the help. I will defiantly be doing the work myself. If it where an automatic i would be re-thinking this. Ive never cracked into a transmission before but with a good write up anything is possible.

i hadnt before i did mine either. Like i said mikes ssr write up shows all the different t56 variants and what was good and bad about them. I put a BUNCH of pics in my write up just in case someone would tell me i did something wrong before i ran it.
ill be using your build thread sooner than later, thanks alot.

Its not realistic to hold that more. The stock gears give out at 750. All the parts are just to small in a standard t56. T56 magnum uses alot of bigger internals. If you dont wanna pay 5 grand for a tranny you wont get one to hold 900at the wheels for a long period of time

Just because something works for one doesn't mean it will work for the other.
I broke my T56 with less than 400whp but at 3900ish pounds (me + car). Local guy is 600+ (with a lot more torque) in a 3600+ (I think) car without him and running a stock T56 and it is doing fine so far.
Point is, it can fail at anytime no matter what the power level...some people get lucky, some don't. It's like a 10 bolt, some will take abuse, some will fail at stock power. I'd say T56 is the opposite, most will take abuse, some fail stock power..it just happens. I personally wouldn't trust an anywhere near stock trans in my heavy *** high HP car, so if I ever decided to keep the manual trans and build my car to 900+hp, it would be getting a built trans ASAP.

and you see no one on here running it. gotta find lots of parts and donor trannys which will add up the price really quick. you could do what you want. and yes I do own a t56 and my car makes 700-800 at the wheels. not trying to start a fight with you man im just giving you my input. those are the options that 99 percent of people do on here. you can do what you want
for HALF as much as a TR6060 a T56 can be built to withstand 900rwhp with the right components, contrary to what you have stated.. whether or not the parts will be easy to come by it is possible and economical compared to get a built TR6060.
Im sorry your transmission blew at 450rwhp but that is irrelevant to the subject at hand. Oh and there are plenty of people running around with this hybrid Transmission.. TDP also sells there own version of this and has sold ALOT of them.
At the end of the day it comes down to bang for buck and this hybrid fits the bill. For 2500 less than a 6060 ill take the less "refinded" shifts and put that money elsewhere.

Spoke with TDP today.. 1700 plus my GTO trans gets me a 32 spline main shaft, full tranny rebuild with top quality parts and all the fixins.. Sure is a far cry from 5k. Matt said he personally knows of at least 10 people running around at 1k or more with this trans. Looks like we have a winner

Lets recap and put an end to the "T56 cant hold 900rwhp reliably" topic..

The 900rwhp you are wanting to make is with a turbo setup. The SSR 32 spline main shaft is only to upgrade the 27 spline. But that is all it will do, help the main shaft. The gears are the weak point here, I have pics and can post tons of turbo sheared T56's. I have less broken Tr6060 gears than I have t56's. No company will warranty you a transmission if it breaks of sheared gears. I have had them cryo treated, micropolished etc... end result is the same. Here is what is going to happen...might not be right away but it will happen. This is at 880rwhp on a 3rd to 4th gear pull roll racing.

Thanks for posting those. That looks pretty nasty. What that looks like to me is the gears being heated up to a point that they are weakened and start shearing. Would you say the same? if so, would more adequate lubrication not be a viable option? Do you know exactly where in the transmission this failure takes place because it seems to be very consistent with other photos ive seen.
what I want is someone to tell me is that they have installed a lubrication pump and installed the outputs in the appropriate location and still the gears have sheared. If I can get a documented case of that then I will by a TR6060
