Ok so i ran over a rock and it punctured my transmission pan i replaced the pan put new fluid in it. It will still slip out of gears on low gears when im driving over 20 mph it shifts perfectly when i hit the rock i drove home fine i was 1 mile away from my apt then it started having problems it wouldn't shift till i was at 3 or 4 rpms but that only happened for 2 blocks i was 2 blocks away so i dont think it could of messed up the transmission. when i got home it leaked the fluid out all the way behind my car so i wasent running it dry just low and i have been driving it that way for about 10 days. someone said it might be the filter go misplaced idk whats yalls input? PLEASE HELP!

 

What kind of fluid did you put in? It requires a certain kind of fluid to work properly. If you are certain you used the correct fluid, then take it to a shop with the capability of reading the codes in the transmission computer. If it's not shifting properly there will be some fault codes in there that will help diagnose the problem.
