68 transmission ??

[HWork]

OK, for the last two months my transmission at certian times for no reason will start to go into grear really hard, only when going into drive (when backing up then going back into drive is when it typically happens). The unit is always warmed up and been driving for a little wile before it does it. You can kill the engine restart it and it is gone. Of course the dealer thinks I am wack and they are not going to help, and the darn thing will not do it when I schedual my two week in advance to see the diesel tech. No transmission codes. I have the DPF delete and an AFE intake. Any advice would be great.
