If you hear a knock, generally it is in the rotating assembly. (wrist pin to the piston, or main
bearings) If it is more like a clicking sound then it could be a lifter the sound will generally
be confined to the upper portion of the engine
Usually if an engine is failing it will exhibit poor power which may seem like
transmission problems.

(I experienced this first hand driving a 66 GTO on a long distance trip, the knocking
became louder and then two rods exited the engine through the oil pan).

I'm trying to find the location of the transmission fuse in my 2001 hyundai santa fe.


If the fuse blew the car would still have a gear to get you home by default, so the fuse is not the problem, but if you would like to check it is under the hood.

What would cause a knock in my engine/transmission when I am breaking from 20 to 15mph in a 2002 hyundai santa fe?


Depends on whether it is some internal knock or external to the engine/transmission. If external you will need to have the transmission and engine mounts checked.

If it is internal and definitely originating from the engine or transmission it is impossible to say what the cause is without testing the car. Changing the fluid in the transmission will not cure a knock of the kind you have described.

1998 SR5 O/D Off Light


Well the obvious answer is that the auto transmission has a problem. The normal diagnosis would be the solenoid that engages 4th gear is faulty and the vehicle stays in 3rd gear. So you have to know the diagnostic code that comes up in this condition.

But just as a precaution first check if the engine coolant is at right levels and thermostat is functional. Sometimes fault in engine cooling system can also lead to the O/D light (over drive) coming up.

To get some details on how to check the diagnostic code you can refer to
http://personal.utulsa.edu/~nathan-buchanan/93fsm/autotrans/31diagnosi.pdf

If you are unsure it is best to take the vehicle to an auto transmission specialist (not the Toyota service place) and get it checked. By the way should not be anything to worry telling your dad. It is nothing that you could have caused. Simple vehicle mechanical issues.

While merging onto the highway when my car hit 3 and 4th gear the engine seemed to "stutter/misfire" during harder acceleration. Check engine light also flashed briefly during hard acceleration. Dur


Could be a transmission problem or something as simple as bad spark plugs.
The engine is under the most load when RPM is low and you are trying to accelerate, such as when it upshifts.
You should have the computer checked for trouble codes and hopefully that will point you in the right direction to test.
If the spark plugs have more than 50,000 miles of wear you might start with replacing them.

When my car starts to move forward and hits first gear it switches quite hard, a noticeable jolt happens. also the engine light is on and i took it to a dealer and they said i have to replace a kock sensor


A snatching shift indicates low fluid. Put the car in park and with the engine running check the level on the transmission dip stick. If low you can top it up by adding extra fluid via the dip stick tube: add about a pint at a time and check the level between top ups. The knock sensor might have been triggered by heavy shifts so I would reset the error code and run the car with a full transmission and see if the code comes back. If the knock sensor if triggered the ECM on most modern cars may put the transmission into a limp home 'safe' mode. With luck in 1997 such things were yet to be enacted. If so just make sure the timing and all functions are OK on the engine.

When you put truck into gear at an idle (AT) once the truck is warm, I can hear a sharp knocking noise coming from the engine. Injectors have been changed as well as the pump and oil pressure seems to...


Check your engine and transmission mounts. A broken engine mount will mimmick engine knocks. Raise all 4-wheels, and with a partner, have them place the vehicle into gear. Have them accelerate and check the movement of the engine/transmission. They should be not much movement. Visually inspect these mounts for cracks, splits, etc. Removal and replacement is very easy and low cost.
If they check out:
Check your Knock Sensor for voltage and remove and replace if needed.
It could be other things: some are (but not limited to):
Incorrect Fuel Octane Grade.
EGR system malfunction.
Vacuum Leak.
Engine Control System malfunction.

95 Lexus ES 300 check engine light is on and the overdrive off light is flashing


chances are you don't have to replace the computer. the reason i tell you this is because you did not mention that the car is running lousy. no complaints of rough idle or missfire or hard starting. chances are that your engine speed sensor which sends the signal to the computer which then controls the transmission is most likely the culprit.. and it could just bhe that there is a loose connection between the two. if that is ok then your transmission control module is faulty. this is not the main computer, but the gobetween the trans and the ecm.. hope this helps please rate this...thanks(btw....the knock sensors control timing not the trans mission)
