Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

I backed out of my driveway stopped my truck like always put it in D to drive heard a loud clunk noise and now I have 1 and 2 gear only to use the truck was stationary was on a main road I changed the transmission fluid screens filters everything flushed it out and still the same thing a lot of people are saying it's the sprag unit I have no idea what that is I have only hauled a few things with it when we were moving we only moved eight miles down the road used a trailer and the tow gear that is on the truck. Also about a month before this happened the stability system light came on and said disabled but has not done it since also my truck is very clean always serviced according to the manual and is in very very good condition
