Just for your info the 03 dodge has a 48re trans and this trans will take all the same mods that its predecessor has the 47re. Vb has some changes and the nsbu switch has gone digital so the cases are different. The rooster comb is different on the vb but its easily changes out. They still have steel planets but have gone to more pinions and made it more beefier all in all dodge has out done them all buy not fixing what already works later

Part of the design was to increase the durability to 150,000 miles. Major changes were made to the pump, valve body, friction material, gear train, and park system. The pump has 20% higher capacity for adequete cooler flow. The addition of a seal ring to the reaction shaft allows the TC increased capacity for clutch engagement. The impeller hub on the TC is machined to accomadate the seal ring. The valve body provides increased line preassure in 3rd and 4th and during TCC operation, and allows the ability to engage the converter clutch in manual second gear for greater towing performance. The valve body also permits Tcc engagement in drive-second gear for cooling protection, if sump temp goes over 220 degrees. This may result in change in shift quality however. The direct clutch in the 48re's overdrive unit has 23 all new discs with friction material on one side only. The four disc rear-clutch pack has been improved for greater durability. One disc was added to the front clutch for increased reverse torque capacity, annd the overdrive has 5 discs for non-HO and six for HO. The kickdown band lever has also been increased. The entire gear train assembely is new, and all planetary gear sets and the overdrive carrier have a six pinion design. The front and rear carriers are made out of cast iron, while the overdrive carrier is made of powdered metal. The 48re's drive shell is thicker for heavy duty reverse operation, and greater durability, and includes new thrust washers. To deal with higher vehicle weights the park system has been enhanced with a new rod and wider park pawl. 2wd extension housing is designed to work with larger slip yoke. Unlike previous auto tranny's the 48re is designed to work with an exhaust brake as well.<br>

Okay, now how hard is it going to be to put one behind a 300HP 1st Gen? ;D
