What transmissions work with a 4.3 Chevy?

The 4.3L Chevy engine (a small-block V6) has been used with a wide variety of transmissions over the years, depending on the vehicle and year of manufacture. There's no single definitive answer. To know for sure which transmissions are compatible, you need to specify the *year* of the 4.3L engine.

However, some common transmissions paired with the 4.3L include:

* Automatic Transmissions: 700R4, 4L60E, 4L60E, 4L65E, TH350 (less common in later years). The 4L60E family is very prevalent.

* Manual Transmissions: SM465, NV3500, and various others depending on the application.

Crucially: Even within these families, there are variations. Bolt patterns, bell housings, input shaft diameters, and other dimensions can vary depending on the specific transmission and the year/application of the 4.3L engine. A transmission that worked with a 1990 4.3L might *not* work with a 2000 4.3L.

To find the correct transmission for *your* 4.3L, you need to:

1. Identify the exact year and model of the vehicle the engine came from. This will greatly narrow down the possibilities.

2. Check the engine's specific bellhousing pattern. This is a crucial piece of information for compatibility.

3. Consult a parts catalog or a reputable mechanic. They can help identify the correct transmission based on your engine's details.

Simply stating "4.3 Chevy" is insufficient information to determine compatible transmissions. More specific details are required.
