G-Tek repaired my 924 Turbo, properly to Specs. After having repairs at another shop, the car was popping out of gear. I was dismayed and of course the mechanic said he did nothing to cause this, and basically scorned me. I took it to 3 other German and Porsche specialists, none could tell me why the car was popping out of gear or even had a clue. G-Tek had the problem isolated within an hour, turns out the mechanic that did the brake lines, the one that scorned me, wrapped the brake lines around the Transmission Push Rod, and VOILA, car pops out of gear. G-Tek diagnosed the problem and gave me the option to return it to the fellow that did it. I replied G=Tek with, Why would I do that, so the car can come back with something else wrong? I asked G-Tek to fix it, and they did, at a great price, I was pleasantly surprised. G-Tek could have lied to me and said it was a major job, like take the Tranny out, that's what Specialist #2 wanted to do at thousands in cost. G-Tek got it right the first time,I wish I had found G-Tek before I had spent, $#@$#@$ thousands at other SO CALLED PORSCHE SPECIALISTS only to have the 924 Turbo I gave my Son, Run NO BETTER, and in fact worse than when I dropped it off. Want it done right? Take your Car to G-Tek First.
