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.

Oil was appearing into radiator overflow reservoir. I changed the radiator fluid twice, and flushed. Problem was not solved so I had it looked at. Engine oil was not frothy so we knew it was not a head gasket. Then we checked the transmission fluid, I was down a quart. We then knew it was a hard pressure line into the radiator that cools the transmission fliud. Bought a new radiator, and ever since had no oil in the reservoir.
