Location: Muskego, WI | I need to know if this is a 318 (internally balanced) or 360 (externally balanced) torque converter. This TC came with my A518 overdriver automatic (in an early to mid 1990s Dodge van with a Magnum engine), but I don't know what exact engine it was mated to originally. Do the weights mean its externally balanced? Or is there a marking on the TC (or trans) that will tell me? I need the appropriate lock-up TC for my 318.

Location: Muskego, WI | I think I found the answer, it appears the torque converters were universal for the Magnum engine series while the flex plate carried the weights for external balance for the 5.9 Magnum.

Location: NorCal | That site claims "The 5.9 Magnum uses a weighted flexplate and a neutral-balanced converter from the factory."
This is true of only the '96-later Magnum, the '93-'95 Magnum has the weight on the converter. The number 642 is a common rebuilder's number for the '93-'95 5.9 Magnum converter, it has a 91 gram square weight.

Location: NorCal | Forgot to mention, the 642 converter is a lockup. PK52118328 is a 518 (46RH) OD transmission from a '93-'95 Dodge PU, build date 2158 is around October/November '94. |
