Question Syncro application ? All t-56's the same ?

Internally ? I have a syncro assy I am trying to sell, but I have no idea what applications it will fit. GM Part # 12523191 Also, there are different types for different gears ? My local dealer does not want to help.....

That looks like a 1-2 slider assembly. Yes, it will work on LT1 or LS1 transmissions, any year (93-02).

For what it's worth, D&D sells them (the 1-2 assembly) for $149. Been there, done that. I believe they sell just the slider itself for $129 or so.

Andrew,

Thanks for the reply. Is there any way for me to tell dimension wise if it is for 1-2 or 2-3, etc ? It is still in plastic, but I could put a caliper to it. $149 eh, I thought the retail # was outrageous. I have the res set at $90, so maybe it will go. 6 people watching last I looked, but only one bidder so far.


Thanks again,
J

The 1-2 slider (I have one sitting here on my desk ) is 4.5" in diameter. The 3-4 slider is smaller... (those are out in my shop ) but they're probably around 3.5" to 4" in diameter. The 5-6 and reverse sliders are even smaller, but that one does indeed look bigger.

Looking closely at the picture, it looks like the black ring does not have the fibrous backing material - it's smooth. That's because the 1-2 assembly has a fiber cone that fits up in that blocker ring (I put a trans together last weekend with a new 1-2 slider assy, and it came out of the box just like that). That's why I think (from here) it's a 1-2. But the diameter will indeed tell you.

And for what it's worth, I think $90 is a fair reserve price. Hmmm, temptation.

Good luck!

-Andrew

It measures out at 4.668" with a caliper. This is with the plastic, though. So it looks as though it is indeed a 1-2 syncro assy. No fibrous material either. Thanks for your help.
