*Please read description*
GM/Tremec had 3 styles of quick connections for the T56. Two of which go to the internal slave cylinder (i.e. a hydraulic throw-out bearing).
If you are using a braided -4 AN hose with a T-56 hydraulic throw-out bearing, you *may* need this adapter to connect the two. There are two fitting styles for the T-56/TR6060 hydraulic throw-out bearings. They are easily identified by measuring the bore of the fitting bore on the slave cylinder (where this fitting would plug into). This fitting measures roughly 5/16 in diameter. The other fitting (#2) measures close to 3/4″.
(Please note: If you purchased an AN hose from Pro-Touring Products prior to January 15 2022, you received a -3 AN hose. Please contact me for the correct adapter fitting.)
