Ok first it the transmission started slipping when l was stopped going into first gear. Then l checked fluid and it was low so l put it more and it solved my problem. then after driving about 100 miles it all started messing up. l was on the high way and it jerked when it shifted then whenever l pushed the gas over 2000 rpms it would feel like it was pulling instead of pushing and wouldnt go over 2000 rpms. then when l finaly got home l put it in reverse and l would act like it was in park. and while its in park it wont rev over 2000 rpms. What is wrong?

It sounds to me as if u have valve body problems, jack the car up & remove the trans pan, make sure u have container under it to catch the oil. Check the fluid u r probably going to find a lot of ''silver flake'' in the oil this indicates that a part in the transmission has self destructed. If that is the case l would take it to a trans shop, if however u do not have the silver flake then try changing out the filter & fluid & put a trans conditioner in also. No promises but worth a try.
