How to keep transmission cool
Antiwear additive fights summer temperatures
GARY Watts’ 18-speed Road Ranger was working hard.
It was a hot day but the ‘box was running a temp of 120 degrees.
He bought a bottle of AW10 Antiwear and reported that in Queensland’s summer heatwave conditions, the gearbox was running at 80C most of the time and only once, for a short burst, did it run up to 85C.
AW10 Antiwear is formulated to deliver massive increases in lubricant load carrying ability, wear reduction and friction reduction.
If you cut the internal friction and minimise the heat build-up and component stresses, things last much longer.
Controlled engineering type tests on three different oils confirmed AW10’s ability to increase load carrying ability between 46 per cent and 47 per cent, before seizure occurred on the test rig.
The test rig’s bearing temperature was reduced by 69C under stable load conditions.
The torque required to drive the test rig was reduced by between 34 per cent and 44 per cent on tests conducted using two engine oils, indicating reduced machine frictional losses and efficiency potential.
The long term field experience is just as impressive.
Phil Riseley of Riseley’s Bulk Haulage operates a Detroit Series 60 powered Freightliner FLC112 that has an 18 speed Road Ranger gearbox and Eaton diffs.

Using AW10 resulted in smoother gear shifts, especially when cold. There was no “click” on fast changes and a slight engine rattle disappeared.
Operating temperature going up the Toowoomba Range showed a 25C reduction for the gearbox, 15C cooler for front diff and a 20C reduction for the rear diff.
John Tasker’s 3.2 litre diesel, automatic Pajero experienced a heating up of the transmission tunnel when the vehicle was towing a 1500kg caravan.
“At 45,000km I added a dose of AW10 at the rate of one per cent of the gearbox oil volume, to the auto transmission. The problem was solved.” he said.
“I have now been using AW10 in my auto transmission for 45,000km with no problems whatsoever with no more excessive heat and gear changes appear to be smoother.
“The Pajero had all its oils and fluids changed at the 90,000 km service, with AW10 again added to the auto transmission.”
AW10 Antiwear is formulated to deliver massive increases in lubricant load carrying ability, wear reduction and in both friction and heat reduction.
AW10 Antiwear is also suitable for manual transmissions, final drives, hydraulics and engines.
AW10 Antiwear boosts oil strength; has outstanding corrosion control; engines, transmissions and diffs roll smoother; is ideal for automatic transmissions, power steering and hydraulic applications; it offers the best protection for automatics when towing; it allows smoother, slicker gear changes and it reduces stress in all components.

STAY COOL: Gary Watts' hard working Mack suffered from high transmission temperatures. AW10 Antiwear solved the problem and reduced temps.
