tonight i had to go let my girlfriend in the gate of my sub divison.. and i pulled a u-turn to come back in and i went to give it gas... and its like the tranny kicked outta gear for a second then kicked back in... possible signs of it starting to go out? the truck has 86k on it right now...it has done this before.... or could it possibly be the rear axle going out again? any thoughts... thanks

 

Check the fluid level and condition first.
Then the linkage adjustment.
Start with the basics

 

how would i go about checking the linkage? the last time i checked the fluid was about 2-3wks ago.. didnt smell burnt and didnt look any different then what it should be
