    Hi, Last friday we got the boat out of storage I towed it home and I noticed that in tow haul mode the truck was riding out 2nd gear pretty long. We took it to the lake and all was ok other than riding out the gear. Took the boat off, drove about 300 miles, everything felt normal. I notice that when I take off from a light it is riding out 2nd longer than normal. Then it has soft smooth shift (I would not have known it shifted if the rpms did not drop) It does not do this every time. I Checked the fluid and it is clean and does not smell. I know nothing about trans internals. Any ideas what the issue may be? Thanks
