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.

1997 Jeep Wrangler Owner Comments

problem #1

Nov 032010

Wrangler Sport 4.0

  • Manual transmission
  • 146,000 miles


When I was on the highway, my transmission started getting rather difficult to shift in my 4.0L, 5 speed (AX-15) Wrangler. By the end of the trip (approx 50mi), I could not shift at all unless I turned the engine off first (thus limiting me to 1st, 2nd, or rev). I limped it back home to find out from some very knowledgeable friends that it was the synchronizers in the transmission. These line up the engine & trans, thus allowing smooth shifting. These copper synchros wear/break excessively due to larger tires (I have 33"s with 4.88 gears), especially at higher speeds (whoops!). There are some aftermarket shift kits that have TITANIUM synchros. With these, the once vulnerable AX-15 trans is now quite bullet proof, although I wouldn't suggest trying!
