I recently had my ATF Fluid drained and filled with Honda DW-1 at about 90K. ATF Changes in my 2011 have been at 60K, 75K and 90K, all drain & fill (not flushed) with Honda DW-1 fluid. This is the first time I've had my mechanic tell me the fluid was discolored and this is my 6th Honda. Hearing this, I was reminded of late last winter when there was a burning smell after driving a couple miles up a snow covered (packed snow) mountain road. The smell came from the front-end of the Pilot and I remember telling myself the transmission had probably heated up. I assume this to be the likely cause of the fluid discoloration many months later as I don't tow anything & think I treat the tranny very well. Assuming this driving event did heat up the tranny, any reason why this would be? Anyone run into this before? Maybe it was due to some traction issues? My Pilot is 4WD and has all-terrain tires. I plan to do another D&F with my next oil change by the way. Thanks all.
