I recentyl took my 09 f150 to ford because when I turn the wheel around corners I get a vibration,he ask me if it had a traction lok on it and said I didn't no.How can I find out that info,I followed a few post that said to look on my door jamb and I did,it has a number 6 under TR (tranny) and B6 under AXLE,how can I find out what I got for the both of them.

 

6 — 6-speed automatic, 6R80
B6 — 3.73 limited slip
