* TH350 (Turbo Hydramatic 350): This was a very common automatic transmission in 1977 Camaros with 350s. It's a robust and relatively simple three-speed automatic. Parts are readily available and it's a popular choice for restorations or mild performance builds.
* TH400 (Turbo Hydramatic 400): A heavier-duty four-speed automatic, often preferred for higher horsepower applications. It's less common in stock '77 Camaros but a popular upgrade for those seeking more robust transmission.
* SM465 (New Process 465): This is a four-speed manual transmission, known for its strength and durability. A very popular choice for those who want a manual.
* Muncie M20/M21/M22: These are all Muncie four-speed manual transmissions, with the M22 being the strongest and most desirable (but also more expensive and difficult to find). They are strong and durable but require more maintenance than a modern transmission. Less common in stock '77 Camaros than the SM465.
* Tremec TKO 500/600: These are popular aftermarket five-speed manual transmissions often used in performance upgrades. They offer better fuel economy and performance than the original four speeds.
Important Considerations:
* Bellhousing: The transmission's bellhousing must match the engine's block. Different transmissions use different bellhousings.
* Driveshaft: The driveshaft length will need to be correct for the chosen transmission. This is crucial to avoid vibrations and damage.
* Crossmember: The transmission crossmember might need modification or replacement to accommodate a different transmission.
* Computer Control (if applicable): If you're going with an automatic, make sure the transmission's control system is compatible with the car's computer system (if it has one). Older cars often don't have sophisticated computer control, while newer aftermarket transmissions might.
Before purchasing any transmission, it's highly recommended to consult a mechanic or parts supplier specializing in classic Camaros to ensure compatibility with your specific vehicle. They can help you determine the best transmission for your needs and budget, and advise on the necessary modifications.
