Transmission problem
1985 Toyota Echo Automatic 100100 miles

since i had a service done last year, my car has been jerking when i accelerate off from going around a roundabout or accelerating quickly up a hill. it sometimes does it when picking up speed from traffic lights too. it's fine at higher speeds and changes gear smoothly when driivng along. last year when i went to pick my car up from service i had to go return later because he said the apprentice had drained the tranmission oil and he needed more time to get it back to me. i had it serviced for 100,100km this week and so oil levels are fine. not sure what to do and whether i should get it attended to. any suggestions about what it could be and what i should do? thanks!
