I recently bought my Son a 2005 Gt that has a Vortech V2 Supercharger among other mods including a "Tremec" transmission. The PO doesnt know anything about the trans except that the guy he bought it from said he chaged it out because of the increased HP. I say all of that to ask....The Hurst Competition Plus shifter is so sloppy that you fight to find the gears. Hurst says they can sell me replacement mounts but the shifter "base" isnt loose...Its the linkage. I am preparred to buy a new shifter but if this shifter isnt the correct one for the transmission I would be throwing $ away. I am not new transmission swaps as I have a Dodge Viper t56 in my 66', I just cant see any casting numbers to know what I'm dealing with.
