|I was on the highway driving at 60 Mph. The engine rev high and low as the |transmission engage and dis-engage. I pull over to side of the road (within |1 min max) to park the vehicle in the safe place. I quickly notice that my |transmission oil return line from the rad came apart spray the oil |everywhere. Re-connect the hose (hose clamp loose) and top up almost 4 L of |transmission fluid (my friend brought the oil for me). Drove it for about 5 |min to get off the highway then check for oil again, I have to add another |4L. Drove it home. It seems to run fine then. Now, when the engine is |warm, It jerk a bit as it drop into final gear. When I step on the gas to |accelerate, it change gear and accelerate fine until it go back into final |gear and then the process is repeated. I only notice this when the engine |is warm (15 min or more driving). |My question is did I damage the transmission by loosing the oil along the |highway? |This problem above, does it has any connection to the lost of transmission |fluid or just coincident? |Before this incident, I don't have any problem | |Thanks for your help!
Firstly, it is possible that you were losing tranny fluid for a long time and didn't know it. What happened to me with cooling system, was losing cooland -only- when system was pressurized, and it was blowing out through a crack in the bottom radiator hose onto the roadway. Of course, when the car was stopped, everything *normal* when engine cooled off.
When your tranny fluid line finally blew, chances are you had already been driving around for a while on low fluid. It is possible there is some damage in there; I'm not a tranny guy, but I would say the odds of there being some damage in there are greater than 50/50.
Otoh, on the bright side, if there is one, you're mobile. Outside of that tiny *jerking motion* you mention when it slipes into hi gear so to speak, you're mobile and comfortable. As long as you check and keep your tranny fluid topped up now, there should be no further damage. However, that said, if one hose line blew, that and all other rubber hoselines need to be replaced, otherwise, it is only a matter of short time before you end up stranded with a -trashed- transmission.
Change the tranny rubber hoses, or have somebody else do it.
