So my parents 98 GP is starting to have transmission issues. Car has 158k on it, but really has not be taken care of all that well. Trans fluid was changed 1 time, but way later then i should have been, i'd say around 130k maybe even later. So last week i was driving it, using my GPS, and the GPS failed to tell me i need to be in the left lane. So i jumped the light i was at and goosed it revved er up past 4k and shifted to second and while pulling it hard in second 3-4k RPM it jerked hard, lost power for a second and then came back in the power. Right after that it i smelled something weird. On the way home it was acting a bit strange, sometimes shifts be kinda slow and lethargic, or kinda firm, then the next shift would be normal. Also several of the shifts into O/D were clunky. Today my mom drove it and said it was being jerky sometimes. Fluid color wasn't terrible, decent, still redish.
