* Different Bellhousing Bolt Pattern: The bolt pattern on the engine block for the transmission's bellhousing will almost certainly be different between a late-model transmission and a '67 Camaro's original transmission (likely a Muncie or Powerglide). You'll need an adapter plate or a custom bellhousing.
* Transmission Length: Late-model transmissions are often longer than older ones. This can affect driveshaft length and potentially require modifications to the transmission tunnel. You might need to shorten or lengthen the driveshaft. The tunnel itself might need to be modified for clearance.
* Clutch Linkage: The clutch linkage system will be entirely different. You'll need a new hydraulic clutch system or a cable-operated system, depending on the donor transmission. This includes the master and slave cylinders, lines, and potentially the pedal assembly.
* Shifter Location: The shifter location on a late-model transmission won't match the '67 Camaro's. You'll need a custom shifter linkage or a floor-shift adapter.
* Wiring (if applicable): Some late-model transmissions have electronic sensors (like speed sensors) that will require wiring to be integrated into the car's electrical system.
* Crossmember: The transmission crossmember will almost certainly need modification or replacement to properly support the new transmission.
In short, while it's *possible*, it's a major undertaking requiring significant mechanical expertise, fabrication skills, and potentially custom parts. It's not a project for a beginner. Many people choose to use a T5 transmission (a popular choice for this swap) or a more readily available swap kit designed for the '67 Camaro. These kits often simplify the process considerably.
