The thinking was, You can cool the tranny fluid, you can cool it a touch too much for optimum operation of the tranny, (I Believe this is more critical with more modern trannys). Once the aux cooler did its thing, if need be the radiator cooler might have warmed up the returning fluid to a more favorable operating temp for the tranny to be happy with it. BUT with the aux cooler first, you are Not asking the radiator cooling system to suck out a lot of BTU's from the tranny fluid into the water/antifrooze chemical soup circulating in the cooling system, ergo less strain on the factory cooling system. -- Paul Holmgren Mine: 2 57 300-C's in Indy Hers: 05 PT GT R/T HO Stage 1 Hoosier Corps L#6 ------------------------------------ To send a message to this group, send an email to: Chrysler300@xxxxxxxxxxxxxxx To unsubscribe from this group, send an email to: Chrysler300-unsubscribe@xxxxxxxxxxxxxxx For list server instructions, go to http://www.chrysler300club.com/yahoolist/inst.htm For archives go to http://www.forwardlook.net/300-archive/Yahoo!
