Alright, sometimes when I start to take off, especially going up a incline, around 10mph and 1000-1500rpm's my truck stutters pretty bad. Any explainations?

 

I had this happening about two weeks ago, then a few days later my transmission was having a terrible time going from 2nd into 3rd. It was terrible to say the least. Luckily it was a quick, cheap and easy fix...Low trans fluid.

Pull your dipstick with the truck on and in neutral and check your fluid. Mine was 2 quarts low, and with some fresh ATF+4 in there it's running like a champ!

Good luck!
