My hyundai bogs down and then has a hard rough jerk at 25 mph. What is that caused from?
What is your question?
Kinda goes into a high reving state as it starts to bog down and then thats when the rough jerking begins. Kinda like if you were to step on the break at a low speed. I have checked all drained all fluids checked for metal shavings found none. Put new fluids in and still does the same thing. I replaced the old sensor with a new one and it still does the jerking. The sensor i replaced was the one that sits on top of transmission under the air filter housing. I have also checked every fuse all are good. Ran great and then I got this problem and haven't been. Able to figure it out I've gone as far as looking up and watching videos of what could possibly be wrong with it. Wanna be able to drive it again.
What makes this problem better or worse?
It seems to not do it when you start In First into drive.Note that I have an automatic transmission. Would i just be better off getting a new transmission for it?
