One of the easiest ways to identify an Automatic Transmission is to view the oil pan. Click any of the below pictures to view full size.
Notes: If a transmission has a suffix of “C” on it, (i.e. TH350C) this designates the transmission has a lock up torque converter. This is primarily found on transmissions newer than 1980 and can be identified by an electrical connector on the transmission case.
Notes: The 727 is the ONLY automatic transmission that bolted up to a Big Block mopar.
The bellhousing on the small block engine is different than a big block engine. Therefore a 727 connected to a 340 will not bolt to a 383.
Note: The C6 is considered a heavy duty transmission and is preferable in high powered applications.
