The two most noticeable items on the tow package was a Mopar Class IV hitch with 7 pin trailer connector, AND, relatively speaking, a huge tranny cooler sandwiched between the A/C intercooler in the front and the radiator in behind.

 

the trany is difficult, depending on where it was done. a dealer overhaul no tags, it will be in a dealers system, if else ware, could be tags. if it is a reman there should be some kind of tags on it.the tow package from chrysler was hitch,7 pin,trans cooler, heavy duty cooling(fan clutch &radiator)most factory ones had 3.73 or4.10 gears. these were also dealer installed without gears.

 

my 01 1500 has the tow package, and a rebuilt tranny. good truck so far. and it was a steal i got it for $5900 kbb was $10,500 it has some quirks, but well worth it.
