The Expedition now uses a 6-speed trans. The taller first gear more thank compensates for the lower final drive rate when you use the 3.31. the 3.31 will give you less engine noise at highway speeds.           2008 Expedition and Expedition EL AUTOMATIC TRANSMISSION SPECIFICATIONS                 AUTOMATIC TRANSMISSION SPECIFICATIONS     Make/Type Ford 6-Speed Automatic Overdrive (6R60)       Engine 5.4L 3V SEFI V-8     Ratios (to 1):         1st   4.17         2nd   2.34         3rd   1.52         4th   1.14         5th   0.86         6th   0.69         Reverse   3.40     Converter Size & Type 12" 145K (L370 Bypass Clutch)     Converter Stall Ratio 2.30     Lubricant Capacity (pt.) 24.0     Helical Gears All     Oil Cooler Water                   AUTOMATIC TRANSMISSION SPECIFICATIONS         Make/Type       Ford 4-Speed Automatic Overdrive (4R70W)       Ford 4-Speed Automatic Overdrive (4R70W)           Engine       4.6L 2V SEFI V-8       5.4L 2V SEFI V-8           Ratios (to 1):           1st       2.84                   2nd       1.55                   3rd       1.00                   4th — OD       0.70                   Reverse       2.32                   Converter Size & Type       12" Controlled Clutch Apply       12" 145K (L370 Bypass Clutch)           Converter Stall Ratio       2.30                   Lubricant Capacity (pt.)       24.0                   Helical Gears       All                   Oil Cooler       Water                   Mark Replies to this message: nbx (Dec 03, 2007 7:39 am)

Replying to: mschmal (Dec 03, 2007 5:26 am) Thanks for the reply. Had not seen the specs on the current model's converter size, fluid capacity, etc.   I'm debating whether to go for one last Expedition. Age 62 now. Wife and I have bought 11 new Ford suvs since 1981. Have always driven 4WD, but am looking at 2WD XLT due to vehicle initial price and mpg. There are some relative bargains in 08 Expedition due to all the restored XLT standard equipment and the new rear air for all units. But basic economics of ownership of Expedition is difficult when buying new retail--may just keep my 2004 Expedition until it drops.   And considering driving the 2003 V-8 4WD Explorer and buying her a new car? But, would only gain maybe 1 mpg switching from Expedition to V-8 Explorer. Also lack of "no hubs in" 2wd high setting a major negative for the Explorer.   My view is that Ford must get a few hundred pounds out of the vehicle curb weight for the Expedition suv to remain on the market. The current super heavy vehicles are annoying for me to drive and are always going to be gas hogs. (they do their job of hauling and towing)   Again thanks for the reply.
