Part number 3732534 is an A727-B transmission with long extension for the following 1973 truck models:

• D100 with 115" and 131" wheelbase or D200 with 131" wheelbase with 440 engine
• R300 (RM300) 1-ton Motor Home with 125" wheelbase with 413 or 440 engine

3732534 is the production number and the service number.

Part number 2953733 is not a 727 transmission number. 2953733 is also not in the Master Parts Price List (December 30, 1974) as a service part number. This number is likely an internal engineering number or sub-component number.

If the number is 2953738, this number is an A727-A transmission with short extension for 1969 and 1970 M300 and M375 Motor Home with 318 engine. 2953738 is the production number and the service number.
