no, dont know what kind of shifter it is. i thought the trannys were different also, i think the older years have the tko600 and the newer has the tremec 3650 but i could be wrong about the older yrs. i know mine has the 3650 and its an 04.
99-early 01 had t45s late 01-04 had the t3650s, the bullitts had the t3650s, i cant tell what brand it is. i dont think anyone would be able to, its deff NOT a MGW or a HURST, could be a steeda, bbk, upr ect. im sure it has the brand stamped on it somewhere
