Add transmission cooling to drop running temp

An impressive 40 degree drop in transmission running temperature is confirmed after cooler upgrade . . .

John recently visited the workshop to fit a 6R80 Dual Oil Cooler Kit / Cooler Control Valve and a Transmission Service as recommended by us at the RHA Workshop. He then monitored the reduction using a Scan Gauge noting before / after results, seeing a 40 degree drop in various driving comparisons –

Automatic Transmission running temp BEFORE cooler upgrade

Highway cruising (not towing) 100 to 110kph – 98 to 102 degreesC

Towing Jayco Penguin Camper (1.6 tonnes) 95 to 100kph – 100 to 105 degreesC

Towing and climbing long slow incline 95 to 100kph – 107 degreesC

Automatic Transmission running temp AFTER cooler upgrade

Highway cruising (not towing) 100 to 110kph – 58 to 62 degreesC

Towing Jayco Penguin Camper (1.6 tonnes) 95 to 100kph – 60 to 65 degreesC

Towing and climbing long slow incline 95 to 100kph – 67 degreesC

The result is impressive, these temperature reductions give the transmission an extended life and peace of mind travelling.
