About a week ago i was driving home from work on the highway and all of the sudden i lost all gear. I pulled off to the side off the road and noticed that my trans cooling line leading into the rad came off( the one closest to the drover side)i removed the c clip and put the line back on a surcured it and added some fuild started to drive normally for the next few days i babied it and check the level 2x a day and looked under to see any leaks nothing and shifted smooth into each gear then 5 day later i lose 3rd gear before the first incodent i had two codes evap leak and camshaft postion sensor i cleared both and havnt got the light since i replace the camshaft sensor hoping it just went bad and went into limp mode but no improvement. i was wondering if there is anything esle i can check before i pull the tranny pan i have 5 day left on the car i borrowed from a friend and hoping it can be a simple thing i am missing please let me know any ideas on what to check. thanks
