Hi I have a 91 non turbo subrau lagcey. Its problem is that its not shifting untill high rpms. Between 3000 an 4000 and its only is first. Also it revs super high on hills. I have to get a goo runnin start to get up. Or it bogs down an then runs really high rpms just to get up. This is my first car an im not sure what to do. I did try tran tune , and fuel injector cleaner no help
