RECOMMENDATION!! - LOJ has installed F-Body/GTO T56 transmissions, T56 Magnum Transmissions, and T56 Magnum XL transmissions into the 350Z and G35. A T56 Magnum XL puts the shifter EXACTLY in the center of the stock shifter opening, as if the transmission was made for this swap. The T56 Magnum shifter will be 8" forward of the stock opening, and the F-Body and GTO T56 will be 6-8" forward. Tremec does not make a Chevy Magnum XL, only a Magnum XL with a Ford input shaft and Ford faceplate. However, multiple Tremec dealers will build you a Chevy XL if requested, and LOJ has vendors that care capable of just that. If you want a T56 that fits the platform perfectly, spend the extra money up front and build a Chevy Magnum XL.

**Note: Installation of this kit WILL require modifications to the transmission tunnel to clear the bellhousing and transmission.

**Note: For TR6060 Transmission, a custom mount bracket needs to be made as the supplied bushing will not work directly with the existing mount holes on TR6060 transmission cases. The bracket and mount will be in the correct position, but this is not a 100% bolt on affair. Additionally, the shifter postion on a TR6060 is not correct for the G35 and 350Z, a custom shifter will need to be made.

ATTENTION 2006 350Z OWNERS! - The 2006 350Z has a different steering rack than all other years, the hard lines coming out of the rack interfere with one primary on the drivers side header. This is ONLY on 2006 model 350Z cars, Nissan added a speed sensitive variable assist PS system in 2006 that changed the rack design. They left the system in the 2007-2009 cars as well, but changed the rack again in 2007 and our headers work with this rack as well. If you want to run our headers you need to modify these lines or swap out the steering rack. You can delete the variable assist system by switching to a 2003-2005 rack, or keep the system and use a 2007+ rack.
