I think some problems were fixed after '99, but some new problems appeared, whether due to quality issues or related to running design changes. (Just like any model run...)
Noticed a Lexus TSB TC001-05, "Fifth Gear Shudder", for 2004-2005 LX470 vehicles produced BEFORE VIN JTJHT00W#53553516. The fix is to remove tranny, replace tranny breather tube, and replace with new tranny.
Ouch.
So...if vin has higher # than 53553516 trans breather should be fine?? My 2005 lx is 5400...
