Converting a Goblin from auto to Manual is NOT impossible! The rewiring of the Engine harness is mostly a cut and discard process. You do have to find the connector to attach to the reverse light switch which fortunately is the plug for the temp probe in the Cobalt front light harness!. (Manual to auto?, I have no idea!) Even if you had cut the clutch safety switch out of your wiring when you modified your wiring harnesses, it is only 2 or three wires and a connector added to the dash harness to the BCM. I have been informed that you might have to reflash your BCM but the TCM is just pulled out along with a bunch of wires. Even easier, get a manual trans engine harness. Surgery, but not Brain Surgery! Add the clutch pedal and switches, transmission, shifter, cables and brackets, clutch master and slave and piping, different half shafts, Flywheel and clutch assembly, F, R motor mounts. The Goblin frames have multi pattern mounting holes to attach to all Cobalt transmissions. I'm not going to say it is easy but I believe I could(using the magic of E-mail and pictures) walk anyone who has built a running Goblin through this change. Also ask DF Kit Cars, they may have a bundle of parts and instructions, if someone wants to do this conversion?
