zmad5306 Posted July 27, 2022 (edited) We purchases a 2017 NV3500 Passenger yesterday with about 57k miles on it. Its the big boy with the 5.6L. What is the story on transmission/atf service? I see all kinds of opinions on this matter. It seems things may have changed between 2016 and 2017 model years. I've seen anywhere from change it every 30k to it never needs changed. Does it need changed/serviced? If so how often? Is it a drain & fill or does the pan need dropped and the filter changed? Is there a dip stick to check the level? I sure can't find one. Any info on this topic would be a huge help. Thanks. Edited July 27, 2022 by zmad5306 Quote Share this post Link to post Share on other sites
radin2son Posted July 27, 2022 Do you know service and use history? Towing seems to be an indicator. You probably can wait until 90-100k. Quote Share this post Link to post Share on other sites
zmad5306 Posted July 28, 2022 (edited) One owner. Hauling kids around town. So light duty. As far as service history all I know is regular oil changes. I highly doubt the tranny has been touched. We will be using it to haul kids and occasional light towing, landscape trailer with a compact tractor or boat. Both well under its towing capacity. I still don't find where to fill the tranny. I watched a video of the titans. Where they have the filler tube with a lid bolted on. I see no such filler on the NV though.

radin2son Posted July 28, 2022 (edited) Unless someone posts otherwise or you find 2017 problems online, you should be fine with your planned use. Found this general recommendation. Change fluid between 60-100k. Doing it sooner is fine and won’t damage anything. If you bought your NV from the owner, pay for an oil change and have them check out your NV. Unless, you already had a mechanical check. Edited July 28, 2022 by radin2son Quote Share this post Link to post Share on other sites
zmad5306 Posted August 1, 2022 (edited) 2017 and newer with the 7 speed is an entire different ball game. See attached procedure and this video: NV3500 Trans Fluid Change Procedure.pdf Edited August 1, 2022 by zmad5306 Quote Share this post Link to post Share on other sites
