I have a 95 automatic 1.9L. it has 150K now. I got it 6-8 months ago Ive put roughly 20K on it, It started out not locking up in OD until it got warm. it did that for a month. then it got longer before it locks up and now it wont lock up at all. also in the morning when i leave for work at first it wont shift out of first until it gets to almost 6000 rpms. after it does that it shifts fine. I changed the filter and partial fluid when it started doing this about 5K ago. my mileage went from 35 to 28 mpg. Any help would be great.
