My Acura MDX 2002 model has transmission issues,i cant really figure out what causes the transmission oil to spill out continuously even after i have changed the oil hose time without number.each time am on a long trip and the engine heats up the hose gives way and the oil spills out halting movement.secondly sometimes when the vehicle is cruising the transmission disengages and no matter how you throttle the car doesnt move until you shift the transmission stick to N and then shift it back to D5 to continue……how do i solve this and whats the likely cause of the gear disengagement?
Here’s my thinking. If you scan and come up with a p0740 code, this might help but a very experienced mechanic is important. You will need to check the transmission fluid line from start to finish. Next is to check the tcc and pressure control solenoid valve c for proper operation. A good acura mechanic should know these parts. Or at least know where to know about them. Next to check torque converter o ring. If all these are okay, then the torque converter and transmission may need to be changed. What could have caused this problem is slippage of the converter clutch and then fluid contaminated with clutch material will clog the filter and lead to other internal issues. Going forward try to stick to recommended fluid which is honda atf z1 fluid. Many mechanics will probably recommend changing and not want to go through all these stress. But having the idea from here helps you guide your mechanic
The oil spillage has been fixed again and again by changing the hose and replacing the oil.even after the oil is replaced and filled with new transmission oil the gear still disengages when the car is cruising slowly.some mechanic said it was the fault was from sensor that selects the gear but another mechanic said its the oil leakage that has affected the gearbox.there is a little sound a jerk that occurs as you accelerate fast and am getting worried it might affect the whole gearbox,am thinking of getting a scan done but i dont know if its gonna come out right because i had wrong scan diagnosis on my volvo S80 which nearly wrecked me because we kept replacing the same parts they scan told us was the fault meanwhile the problem was from a crack on the engine block but the scan didnt dictate that
did you say your transmission oil spills? if yes, that should be the cause of the disengagement. when ever the transmission oil is low it will cause the gear to disengage. i had this issue with a benz C class. mine was leaking from the bottom plate.
The problem is first to know where the oil is leaking from. I’ll advice you fix the spillage soon cause repeated driving without oil in the gear box will cripple the gear box.
