2007 Toyota Tundra CrewMax Cab Limited 4dr CrewMax 4WD SB (5.7L 8cyl 6A)
Rumble strip tranny
 Like everything about this truck except for one unfortunate issue.  The six speed auto seems to randomly start vibrating as if going over a rumble strip.  It feels like a torque converter issue.  Picked up from dealer today after they evaluated it.  They are going to replace the transmission which only has about 800 miles on it.  What adds insult to injury is that they are replacing this with a rebuilt unit.  I for one havent had real good luck with other rebuilt auto parts.  Service said Toyota wouldnt let them order a new one.  They had their crankshaft issue earlier this year now it appears the transmission may be an issue. This truck cost almost 50k!
