Auto or 6 spd big power
untill i cant keep a t56 together i will be keeping it. pulled mine apart at rpm last week and it looked like new after a full year at 850-950 rwhp and prob 150 passes in a nitrous car many in the 8 sec zone @3250lbs and a monster twin. gonna be turbo this year at 1000+ we will see how it all holds again.

So it isnt all rosy with an auto.
Difference here is. In the US, auto is more the norm, so people with a manual car seem to think they're a little different, or that driving a manual is a little more special.
Over here, manual is the norm, autos are very rare. Most see driving an auto is weird. And if you only passed your driving test with an auto ( very rare scenario ) you're only legally allowed to drive an auto.

An auto built for big power can easily be converted to a manual valve body. No you won't have a clutch pedal, but its a start.
Most factory manual transmissions can't handle high power abuse. This is why most of the big power guys use lencos and liberty transmissions and air shifted transmissions instead of production based manual transmissions.
Can a 6-speed handle 1500 HP? Yes, look at what the viper guys are doing. Lots of TT vipers out there.

Older GTSs are using the Viper spec T56 with minor upgrades.
The 6060 is probably the new favorite, as it is for most vette users. The biggest downside to using these built for 1000+rwhp is the cost. Its suprising what they cost compared to an equally capable automatic.

I'll be putting 1000+ to the wheels thru a Viper T56 in the next few months. Do I think it will hold? Probably not. But I will never throw an auto in the car. If the viper spec eats it I'll pony up and throw a T56 magnum from Tick in there...

I spoke to both *Well known shop* & RPM late last week about building me a 6speed to take 1200rwhp with my monster twin plate. International call..
The *Well known shop* guy mumbled something about a level something or other and said to go to their website then stopped talking. Guess he was busy. Even though I bought my clutch & master cylinder from them... I do have to add, I couldn't get *guru*? on the phone like i'd been told to do.
Jeremy from RPM chatted to me for half an hour explaining what i'll need and why it'll last. Needless to say i'll be sending some money to RPM very soon. T56 Magnum with a few mods, tapped for sprayers etc. It's not that expensive if you don't have to change the tail housing/shifter. That's where the extra near $800 comes in! I guess i'm lucky that I don't have an F-body/GTO
I was going to use a standard T56 and see how long it lasts, but by selling that i've recouped near half the cost of the Magnum. Makes sense to me..

Exactly what I did. I sold my still perfect T56 and recouped more than a 1/3 of the cost of the Tick level 5 TR6060 I have now. It's a far better shifting transmission. I decided it would be stupid to break my good T56 then buy the TR6060. I got mine with the sprayers also.

I have an RPM level 6 (I think) TR6060 and an RPS triple carbon clutch rated at 1200lb-ft at the tire. Clutch pedal feel is almost stock but its very tricky to drive, clutch engagement point is very narrow and im not sure what flywheel my clutch came with because it feels pretty darn light.
A stalled auto would be nice for a turbo and could digest some of the cam surge associated with bigger cams.
