alan0043 Posted July 19, 2017 Report Share Posted July 19, 2017 Hi Everyone, I have another maintenance question. Who has sampled the transmission oil in their I-Shift transmission ? I have an idea of how to do it. Thanks for any put, Al 2012 Volvo VNL 630 w/ I-Shift; D13 engine; " Veeger " Redwood, model 3401R ; 5th Wheel Trailer, " Dead Wood " 2006 Smart Car " Killer Frog " Link to comment Share on other sites More sharing options...
beyerjf Posted July 21, 2017 Report Share Posted July 21, 2017 What is Volvo's opinion on the topic? I was under the impression that it is a completely sealed unit, no field service possible and the only way to repair it was to replace the entire unit. Are you trying to predict a failure? I thought that the transmission would give other indications of it's demise. If few people are sampling the units, the laboratories that analyse the sample would have little to go on to give you an opinion on the condition. Their interpretation of the any sample is critical. And all of them will tell you they can't give you a good quality opinion without several samples taken at regular intervals of the same unit, combined with the aggregate experience they have accumulated with similar units.

Jeff, I believe Volvo recommends a flush and fill around 500k on the I-Shift. I don't believe it is a Speedco or self-serviceable unit though. Others will chime in and correct me I'm sure...

beyerjf Posted July 21, 2017 Report Share Posted July 21, 2017 The flush and fill would be an effective PM, but a sample taken once at that point would be borderline useless. Sounds like the current service procedure on modern automatic transmissions. They no longer recommend pulling the pan, replacing the filter etc. They also flush and refill.

alan0043 Posted July 21, 2017 Author Report Share Posted July 21, 2017 Hi Everyone, The video that I have seen on Gregg's site, it looks like he just drains the transmission and chances the filter and refills the transmission with new synthetic fluid. He does not talk about a flush. Unless my idea about what a flush is, I could be wrong on what I am thinking. The transmission fluid is expensive. I don't think that you would flush the transmission with expensive fluid. I was hoping that the oil analysis report would show any metallic particles and the count in ppm. Hopefully Jack has a comment to offer.

Jack Mayer Posted July 21, 2017 Report Share Posted July 21, 2017 I have a comment Volvo says that you should not sample the trans fluid. Change it on the schedule only. We generally change it in all the trucks that we build up, unless it has already been done recently. And if I bought a truck that was "close" to the miles then I'd change it out, preemptively, just so I knew what I had. Otherwise I'd leave it alone unless I had an issue. These transmissions are very robust and designed to go a long time between changes. If it is working well and you are not near a change point then I'd leave it alone. As an example, we are currently acquiring a spec truck that has very low miles (under 200K). That truck will get its trans fluid changed.

The truck does have about 450,000 miles on it. It sounds like I should start thinking about a transmission fluid and filter change.
