Just warning to those who may seek out transmission work on their 996. This was possibly my worst automotive shop experience ever, and I have owned well over 30 cars, so that's saying something. I initially paid GBOX INC in Erie Colorado $10,400 to rebuild a 996 Turbo transmission, with a warranty. The transmission was shipped to them ( I covered $850 in freight). Upon completion, it was installed in the car and became locked up within 100 miles. I had to pay the labor to have the transmission removed from the car again ($4,100) and covered shipping costs to send it back again. They repaired it under warranty and sent it back. Upon reinstallation and driving roughly 1,000 miles it began popping out of gear while driving, this is both aggravating and dangerous to myself and those driving around me. When the fluid was checked it was black, and there was metal material on the drain plug...with only 1,000 miles on that new OEM Porsche fluid. They have ignored my calls and texts for over a year, and are not honoring their warranty or offering any form of refund. With the initial rebuild, all of the shipping back and forth, and paying labor to have it removed and installed over and over I am in this over $16,000 and have a transmission that does not work properly.
