my truck has done this for a while and i was wondering if anyone had a clue as to what is wrong. my truck shifts fine, except when shifting into first. when goin from park to drive it will take up to 10 seconds to kick in then after this it shifts up and down perfectly. i have roughly 115k miles, automatic. any advice will be appreciated

 

You may start with fluid level. When did you adjusted the bands and changed the fluid ?
What color is your fluid ? Is it burnt ? Does it happens all the time or when you first start it in the morning ? Please post your answers. Thank you.

 

Flush yr trans. Mine felt like it was slipping and i flushed it and it feels fine. I would say flush it!!!

 

i had it flushed this summer and obviously refilled. so the fluid level is fine. im not sure what it is. it did seem to get better after the flush but still does it

 

try getting an adjustment or u might have to rebulid it

 

Start it in neutral and see if that helps. The pump doesn't circulate the fluid good in park. When you had it flushed did they adjust the bands and replace the filter? If not that should be done.
