Tech Tip Part Description: Cooler Line Fitting - 545/65/66RFE Transmission

Tech Tip Description: The size of the cooler line fitting threads in the 545/65/66RFE transmission case was changed (from 1/2" to 3/4") in mid-2013 MY. You must use the correct cooler line fitting to match the threads in your case.

The old cooler line fitting (1/2" case threads, for 3/8" quick-connect cooler lines) is 52119547AA.

The new cooler line fitting (3/4" case threads, for 3/8" quick-connect cooler lines) is 68200538AA.

NOTE: 68RFE (diesel) transmissions all use the larger (3/4") case threads, but with 1/2" quick-connect cooler lines. They therefore use a different fitting 55111025AB. The 68RFE case threads did not change.

2013 vehicles (with 65RFE or 66RFE trans) all use 3/8" quick-connect cooler lines, but may have either the smaller threads or the larger threads in the case.

2014 and later vehicles (with 65RFE or 66RFE trans) will all have the larger (3/4") threads in the case. The 65RFE trans (in DS models) will continue to use 3/8" quick-connect cooler lines, and therefore will use the 68200538AA fitting. The 66RFE trans (in DJ/D2/DD/DP models) will change to 1/2" quick-connect cooler lines for 2014 MY, and therefore will use the same fitting as the 68RFE (55111025AB).

2012 and earlier vehicles (with 45/545/65/66RFE trans) will all have the smaller case threads, unless they have been serviced with a new case or replacement transmission assy, in which case they could have either case thread size. Select the appropriate fitting to match the case threads.

NOTE: 2004 and earlier vehicles used threaded (NOT quick-connect) cooler lines. There is NO cooler line fitting available to adapt the new (large thread) case to the non-quick-connect cooler lines. Therefore, if a 2004 or earlier vehicle requires case replacement, and the small-thread (05189883AB) case is no longer available, use a reman transmission assy.
