DETAIL

A small number of reports have been received that identifies a rattle from the transmission at 2800-3000 rpm. Investigations by Land Rover engineers have identified that within this rpm range the transmission brake shoes can rattle against the transmission backplate. To overcome this condition an additional spring can be fitted to the brake shoe cross-strut that will provide tension on the brake shoes pulling them against the backplate which eliminates the rattle.

ACTION REQUIRED

O n customer complaint fit the anti-rattle spring kit following the procedure below.
