'86 hesitation

Maybe someone can help me with this.
While highway driving and hitting it to pass/accelerate "sometimes" I
get a hesitation and a grinding noise like the gears are not grabbing. I
let go of the gas , accelerate again and it clears up. This only happens at
speeds over 40-50 MPH. I have an automatic '86 which otherwise changes
gears fine. I'd appreciate any help in this regard.

i noticed a hesitation on moderate take off in the 86 as opposed to the 84
smoothness. i also noticed a 'burblying' if you will at moderate speeds
when feathering the gas. also, i was getting an intermittent err code 42
and 44. also getting the 2 back plugs fouling. ran the usual chks and
found nothing.

then i started putting in a container of injector jet cleaner with Every
tank full and the problems have 95+% gone away. still evaluating.
