The servo tubes on AXOD & E units may walk off from the transmission case. This causes the servo piston to release and create a no forward condition. There may be insufficient press fit between the tubes and case to withstand the servo apply pressure. If the tubes have been removed for cleaning, the possibility of walk-off increases. Install the Sonnax AXOD & E servo tube bracket 96806. It is an easy-to-install bolt-on bracket that positively retains the servo tubes.
