1998 Oldsmobile Intrigue Oldsmobile SHIFTING PROBLEMS

I RECENTLY BOUGHT A CAR THAT HAD BEEN SITTIN FOR A LONG TIME, I HAVE MADE QUITE SOME REPAIRS ON IT BUT I REALLY HIT A DEAD END WITH HIS PROBLEM.

THE CAR RUNS BUT I HAVE TO ACCELERATE IT MODERATLY TO GET IT TO SHIFT GEARS. I HAVE BEEN RESEARCHING, I WENT TO AUTO ZONE TO CHECK THE CODES ON IT AND TRANSMISSION SOLENOID CAME UP.

I LOOKED UP A DIAGRAM OF THE TRANSMISSION AND IT SHOWS MULTIPLE SOLENOIDS FOR SHIFTING, IM LOOKING AT A TRANSMISSION CONTROL SOLENOID ON THE AUTO ZONE WEBSITE AND IT SAYS THAT JUST ONE SOLENOID CONTROLS ALL GEARS, THE DIAGRAM THAT I SAW HAD TWO CONTROL SOLENOIDS. IM LOST

IF I COULD GET ANY KIND OF INSIGHT I WOULD REALLY APPRECIATE IT.
