Show original supplier description
The Chevrolet Muncie transmission case, identified by casting number 3851325, is a specific component designed for the 1964 and 1965 model years. This case is associated with Muncie 4-speed transmissions and is known to support both M20 and M21 gear ratios, offering a 2.56 1st gear for the M20 and a 2.20 1st gear for the M21. A distinguishing feature of this particular casting is its 7/8" counter shaft, differentiating it from later models that utilize a 1-inch counter shaft. This Muncie case is a crucial part for enthusiasts looking to restore or build period-correct transmissions for classic Chevrolet vehicles from the mid-1960s. While the casting number helps in identification, a complete transmission's configuration also depends on input shaft splines, tooth counts, and date codes, which are detailed in comprehensive identification guides. It is important to note that while this casting is from 1964-1965, some general information regarding Muncie transmissions may apply broadly, but specific identification should always be cross-referenced with detailed charts and guides. The source material emphasizes the importance of correct identification due to widespread misinformation.
