T56 Magnum should I buy and where?

[Vegas69]

Nothing just yet. I don't see to any real alternative to the Magnum right now though. Not if you desire a quiet street type trans.

Yea I already had a quicktime bell short shaft and Mcleod twin disc clutch for a TKO600 but I don't want to do this twice. I can use the clutch but I sold the bell and shaft and am moving to the Magnum. I think the ratios of the CR Magnum make more sense also. First is a little taller, 5th is a rational overdrive and 6th well idling down the fwy sounds relaxing.

Exactly what I did FET, right down to the Bell....

I have been talking to American Powertrain and the level of service I have gotten before the sale has been the best of anyone I talked to, and there is a wide margin in the other direction for comparison. As a customer I do not like feeling as though the rep has better things to do or expect me to have all the answers already. That is why they coined terms like Customer Service , Technical Support and Company or Product Representation.

As far as Jegs, Summit or piecemealing the remainder of my conversion the prices in my quote do not support doing that.
The T56mag price may be set but it would seem they have some room to come down on other peripherals.

Vegas69, Have you heard or read of any issues specifically with the White Lightning? I read about the Blackjack but that was it that I saw.

Exactly my thoughts, the gearing is perfect. I'm still not 100% sold that it will cure ALL my 2-3 shift issues but it will be a major improvement.

Yes, check out the Norwood thread here. He replaced the Blackjack with the White Lightning and it leaks worse.

Something to think about is if you are going to get the T56 Magnum customized.

I went with RPM transmissions because I could get a few tweaks and mods that were not available at the time from others (or at least I could not find anyone else) such as machined bronze fork pads, machined bronze shifter bushing, upgraded carbon blocking rings 1st-4th gears as well as micro-polishing, etc.

Not sure if these are items you are interested in, but it may be and it's nice to get the trans-in-a-box to be ready to bolt in.

Thanks. You are correct that is a point to think about. Liberty has a good rep (from what I've read) for their Tremec mods. They offer several upgrades to the T56 also. That is another problem in itself and something I should have also asked at the start of this thread.

Is there any need to modify your T56 for track duty or do they shift well enough in stock form?

I think a fully prepped T56 from liberty gets close to $3500. I'm not in some delusional state I will build my car on the cheap but I do have a budget. My thought right now is put a stock T56 in for the shakedown of the car and if it has shortcomings then I will address it.

[Vegas69]

That's one thing I havent' decided on at this point. I'm leaning towards having a magnum modified to shift even better. I've caught wind of some high rpm shifting problems with the magnum. I tend to find the weak link with every product so I'll likely choose to do so before I ever stab it.

Not to speak for the vendor, but last I heard RPM retails their Level 6 package for $4995.99. They will give up to $1k refund on a rebuildable T56 core.

These units are tested to 1000 foot pounds of torque.

You are in the same ballpark as the ZR1 'vette, which sees track time and I have not heard too many having issues (I hear more about issues when the tires hop which would not be the case here).

That said, can you really overbuild a driveline? It's just a good excuse to squeeze a bit more out of the engine.

Robert, my stock ls t56 is for sale hint hint
