98 neon with 51k miles. was running ok had purchased for my daughter for when she got her license. it sat for about 5 weeks when i put it back on the road it now has a tranny issue. if you accelarate normally it shifts fine, once you accelarate hard or make the tranny downshift when you step on the gas to pass the shift points get thrown off. when i make a stop after this happenns it wont shift out of 1st until about 25 or 30 and 2nd until around 40. i even tried shifting manually and it still did not shift correctly. only way to correct this was to stop and put tranny in park and this seems to reset something because it will start shifting ok and as long as i don't accelarate hard or step to hard on the gas to pass it will shift ok all day long. any help would be appreciated

 

If only mine did that i would not have to manual shift to keep RPM's up sounds fine to me.
