auto transmission fails

Sounds like your OD band is broken which is a common failure. Also, that model has a plastic bushin for the throttle pressure attachment to the throttle lever. It has been replaced with an updated metal one and there is a TSB out on that. The bushing should be readily available at your dealer or a good trans shop. If this is the problem, the trans may go back to work after replacement and ajustment of the linkage. If you keep driving it this way, it is a sure bet that a not yet failed trans will die shortly as this cable controls the line pressure in the trans. The thrans will have low pressure and burn up because of slippage.
