Information specific to my Series 60/AutoShift conversion

Wiring information

The following table contains the wiring information for my wiring harness for both the engine and AutoShift transmission.  My engine is a DDEC III (now converted to a DDEC IV) and the socket/wire/function may vary for other engines.  The AutoShift wire harness should be standard for all AutoShifts

Also please note that these sockets are for the Deutsch (round) connectors shown earlier in this document.

Shallow Pan Conversion for Series 60

The following is the information for the parts that will be needed to convert a truck deep sump pan system to a bus shallow system.  I want to thank Connell Smalling and Ray Lala for compiling a significant part of this information.

Description

Part No.

Quantity

Shallow Aluminum Oil Pan 23529248 1
Pan Gasket 23522279 1
Pan Bolts 23522281 10
Shallow Oil Pickup tube 23526928 1
Pickup Tube Bracket (half) 23512920 1
Pickup Tube Bracket (half) 23512921 1
Pickup Tube gasket 23505992 1
Dip stick 23515357 1
Dipstick tube 23515358 1

Notes:

  1. The Dipstick/tube must be mounted in the correct location which is on the starter side.
  2. Detroit Dealers can not seem to work without an engine number.  I obtained an engine serial number from a Provost bus:  6R2570524.
  3. On my bus, the above parts gave me slightly less than 10 gallons to the full mark on the dipstick which is approximately 1 inch below the pan rail.
