The B&M 6L80 Locking Transmission Dipstick was designed to allow for a quick and easy check of the automatic transmission fluid level and fluid quality by the vehicle owner/operator without having to go to the dealership. Constructed of billet stainless steel fittings, steel braided hose and black mil-spec anodized aluminum 6061-T6 cap and bracket, this rugged unit allows for both cold and warm fluid level checks and is meant to be left in the vehicle and locked into place. Additional features include an engraved B&M logo locking knurled handle cap and fluid level stamped indicator end.
