I have the same problem occasionally with my 1994 F-250. Does your truck have an overdrive button on the end of the gear selector? If so, does the overdrive light on the gear selector flash off and on? If yes, the problem is probably the same as mine, the "speed sensor" has gone bad. The replacement part isn't very expensive, usually under $40.

its normal you have nothing to worry about it just means it was too rough it happens to me too when i masturbate but not during sex

Yes it is normal for puppies to be play rough. Puppies have a lot of energy and they burn off that energy by playing. They don't mean to be rough, they're just having fun.
Low speeds indicate shifted belts in the tires. If it also pulls to one side, try rotating that side front to back.

No. Teaching them to play rough will cause more problem than it solves. You should play the way they do with each other, rough and tumble is normal, but it is also very soft.
Very rough!
