My car is not changing into gear and it brakes up while driving. It also reve out when driving. whats the prob

It is a 1999 Mitsubishi Lancer. The Electronic Control Unit is OK and the Transmission is ok and the Transmission Filter i just change and the oil.|||maybe a new car would help check your transmission bands sounds like they are slipping|||if you just changed the filter it's not seated properly. Redo it and make sure there's only one oring or gasket where the filter meets the transmission. Also make sure it's full of fluid to the correct level.|||Trany is shot|||DID YOU US THE RIGHT FLUID FOR LANCER U KNOW MITSUBISHI USES A SPACIAL FLUID IF U USED SOME THING ELSE YOU MY FRIED THE TRANS MISSION|||your transmission is slipping. it may be caused by a bad speed sensor, or the trans is bad. next time, do your preventive maintenance before you have a problem: key word being PREVENTIVE
