David Brown has been responsible for many of the developments that have helped to define advances in armoured warfare, and add value to defence solutions. It has developed and supplied the TN-54E transmission for the Challenger 2 MBT to deliver new levels of reliability and performance, and has formulated groundbreaking arrangements for the maintenance of the units. This innovative commercial ‘smart procurement’ initiative, covering the lifetime of the Challenger 2 system, will make significant savings for the UK MOD. The differentials of various pickup trucks (Nissan Titan, Ford F-150 and F-250) and station wagons (Ford Expedition, Jeep Grand Cherokee) and other high-capacity vehicles require synthetic oil with SAE 75W-140 viscosity for its maximum useful life. Frequently these also require an LSD additive.

Avoid crossing or driving on water levels that reach or go over the axis. If this is unavoidable take the vehicle to have the gearbox and ring gear serviced as soon as possible. If water has found its way in, the oil will be milky or its level will be higher. If so, the oil must be changed immediately. Do not use cheap, obsolete or unregulated oils. There are many gearbox and ring gear oils that only comply with API GL-1 requirements. These offer no protection. An oil with a minimum of 60 pounds of protection on Timken® testing must be used. If the technical information sheet does not mention Timken® protection, another oil or maintenance shop must be used. There are many transmissions that cannot tolerate additives. They use synthetic oils, ATF or engine oil to obtain the protection they require in order to synchronize correctly. Caution must be taken with the viscosity of the oil used. Most vehicles in the market require SAE 75W-90 for manual transmission. The use of SAE 80W-90, 80W, 90, or 140 oils will harden the transmission and shorten its lifespan.
