Similar problems here, the guys at tremec told me to give it 1500 to break in, I just hit about 1800 miles and the shifting is improving though. Also I'm considering the white lightening shifter too

So how do you gain more clearance in the clutch if its not disengaging enough?

The Magnum will usually have a little crunch when cold up shifting into third. This is normal and usually goes away after a short warm up. One of the Tremec engineers refers to as the third gear nibble.

Guys with notchy T56 shifting; did you remove the T56 front plate and do a bellhousing alignment procedure referencing off of the input shaft bearing bore?

Crunchy 2nd-3rd T56 Magnum Gear Shift
 

I have not aligned my bell housing, where can I get a procedure for this?

Yes! BTW, I have about 2000 miles on the transmission now and the 3rd gear nibble is dramatically improved and seems to be getting better all the time. It is virtually gone once the gear box gets heat soaked.

Here is a how to:

Thanks Guys,

Installed a quick release clutch quadrant, seems a little better.

Based on what Steve is seeing, I will give it a little more time before pulling the transmission to check the bell housing alignment.
