Part Number: 52119547A$
Part Description: Cooler Line Fitting • 545/65/66RFE Transmission
Issue The size of the cooler line fitting threads in the 545/65/66RFE transmission case
Description: 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. Contact Us at CAGRIS@Chrysler
