Transmission Oil Reports

Automatic transmissions ask a lot of the oil. Not only does the oil lubricate and clean internal parts, but it also functions as a hydraulic oil to operate various components.

Transmission oil can be contaminated with metals, solids, and moisture, and those contaminants need to be removed before they cause problems. Conversely, a test of your transmission fluid may reveal that it’s still in great condition, and you don’t need to change it as often as you thought.

There’s no easier way of knowing what’s going on than oil analysis. We can tell you if the oil needs to be changed, if it’s contaminated, or if there are any problems at hand. Request your free kit today and make sure your drive train is wearing as it should!

An oil report from a Mazda 5-speed transmission. The owner reported that the transmission had been grinding for several years before it finally got stuck in second gear. Metals read excessively throughout.
This transmission has a problem, evidenced by the jump in iron compared to the previous samples.
This Nissan Automatic transmission developed a coolant contamination problem, and the used oil analysis report shows excessive iron resulting from contamination and the oxidation that it caused.
This is a used oil report from a Fuller transmission with almost 500,000 miles on the oil. The sample looks pretty good. Copper is a little high, but it might just be wear-in or accumulation from running the oil so long. Insolubles tested high, suggesting oxidation of the oil, so the oil does need to be changed, but it's a pretty good report considering the mileage.
An oil sample from a Dodge differential that's suffering from water contamination, possible dirt contamination, and a whole lot of wear at steel parts.
An oil sample report from a Ford transmission showing increasing metal trends compared to the previous sample. Silicon is also higher than it was, but the owner didn't give us much information with this sample. Maybe metals are higher due to accumulation on a longer oil run or wear-in from recent work, for example.
An oil sample report from a transfer case. The owner wondered if the oil had ever been changed, and the high aluminum and iron values suggest the oil probably had never been changed.
An oil analysis report from a Nissan transmission that requires a particular type of oil to be used. If the wrong oil has been used (as was the case for this transmission), we can often tell, based on the oil additives.
