I own a 2018 Pilot Ex-L now with 66K miles. “Transmission Fluid Too Hot” warning came on in early 2019 when had approximately 32K miles. Returned to dealer and transmission replaced. 15 months /34K miles later and the “Transmission Fluid Too Hot” warning came on again today. Over the last week or so have noticed the transmisson “slipping” between 10-40 mph (especially going uphill) and the RPMs fluctuate 100-200 RPM. Will be looking for Honda to replace the second transmission as well. asHave seen discussions on this site regarding TSB 17-014 That described similar slipping/RPM fluctuation in 2016 and 2017 pilots. Have others seen this problem on 2018s? Is there a TSB on this issue for 2018s? Frankly, I’m leary that a software update/3X fluid change will solve this problem - three transmissions in 66K miles seems to be design flaw. BTW - also owned a 2006 Pilot that had transmission problems and reluctantly let it go at 160k when it needed a new tranny. I have been told by two reputable independent mechanics that need to add a second transmission cooler.
