Ok some im getting some concrete put in my shop and had to move everything out and down to my MIL about 3/4 mile down the road round trip. Put the pioneer in LOW, go down the road about 20-25mph don't notice anything. Unload the trailer, same thing LOW range coming down the road running about 22mph give it some gas it starts bucking like its running out of gas. I don't think it would have been the limiter because when it did it I had to slow down and turn into my driveway and got it up to 32mph in low range. I believe right around that mph in low range its shifting into 6th gear and I wonder if it was like hanging up in 5th. I wasn't able to duplicate it, so im kind of scratching my head here. Anyone else had an issue like this? Ive cruised through trails in low between 20-25mph and have never had an issue before.
