T56 Magnum White Lightning Shifter - update on the way

While its true the newest breathers have a spring-loading and can hold a small pressure....it is quite small and certainly well below 10 psi.
The spring loading is there to avoid splash- entry and not for seal function.

6-7 psi was what the Tremec tech advisor told me.

What shifter doesn't leak?

Anybody else had problems with the factory tremec shifter?

The latest design White Lightning shifter (from American Powertrain) doesn't leak.

The first several iterations did.

The factory shifter rattles, rather badly, no matter how much I shim it.

White lighting is confirmed dry....even on track?

[parsonsj]

Dry as a bone in my customer's car. He's had several months with it now with perfect results... but he doesn't go to the track.

Edit: the earlier ones seemed to leak only in high RPM conditions, and I tested the latest one (hard) in that sort of situation. The new seal sure looks impressive.

Donny, did you see my post #16 with the pictures of the WL generations I had in my possession for awhile?

John, can you confirm if the one in your customers car looks like that third one? From memory I mean, I do not intend for it to sound like I would ask you to look at it.

Thanks,

Robert

I still can't believe these manufacturers make parts and don't test them. It's beyond me....

Mr Goodlad,
I currently have a T56 Magnum with the stock Tremec shifter and I'm interested in upgrading to the Hurst Blackjack shifter. But I don't see any reference to an individual part number for the just the shifter. My question is, is the Blackjack shifter available separately or is it only sold with a kit? If the shifter is available can you tell me what part number I would need to order?

I had the third version installed in the forward position and it leaked like a mofo! Got in touch with APT and they admitted there was a problem and sent me the new version IV (they were really good about it even tho I live in Australia) I have now installed the new one (this time in the rear position) Drove for around an hour and had zero leak. I did take photo's to show what the new seal looks like but I lost my phone an easy way to tell is that the new seal is a more square/rectangular shape and it covers the shoulder on the ball, where the other round seal did not. Hope that helps, can't do much more without the pics
