93 Nissan Sentra transmission problem?

I have a 93 Nissan Sentra with 216k on it. Lately and intermittently when driving at 60 mph, it won’t accelerate unless I have the overdrive off and makes a gurgling sound. Does this sound like a transmission problem? I hate taking it to the mechanic because it is producing this symptom intermittently and never produces it to the mechanic and they just give the car back to me in the same condition!
