You should diagnose your vehicle with a scan tool/code reader to verify if there is a stored troublecode in your vehicle. The extracted troublecode will help you identify the fault of your vehicle's problem.

It might be a problem with shift inter-lock mechanism?

new o-rings and clamp should installed if they are as old as your car.

1.First inspect the transmission linkage for the forward for a loose connection, if it was in order, then go the next step.
2.There are two planetary gear sets in the transmission, the forward and the reverse. The forward planetary gear set is broken.

Visit this site to see the planetary gear set.

Scroll the screen almost to the bottom and you will see a planetary gear, it looks alike to a pencil rotating sharpener.

You have to replace the neutral switch. Is located inside the engine compartment, on top of the transmission where the shifting cable is. It cost about $30.00 dollars.

"sometimes when i break i can feel something weird which causes the trac control light to pop up." - Could be an abs sensor or module problem. Cannot be solved online sorry

P0750

The shift solenoids that you requested- XS4Z-7H148-AA is an on/off shift solenoid. There are 2 on the valve body. The price is $43.37 ea. XS4Z-7G484-AA is an pulse width modulated shift solenoid. There are 3 of these, at $92.92 ea.

That sensor replacement was easy. Drop the pan, unbolt the sensor and replace

"also whats the difference between the vss and abs semsor??" VSS is for the vehicle speedo ABS is for the brakes

I'd be surprised if changing the VSS will make an impact with the repair. The other 2 is where i out my money at but an opinion from a repair shop is needed.

Does that happens only when the engine is hot or all the time? Have you checked the tranny fluid level?

Possible Causes of Engine Hesitation or Stumble:

Dirty fuel injectors (cleaning the injectors often fixes this).
Bad MAP (manifold absolute pressure) sensor
Bad TPS (throttle position) sensor
Bad or dirty MAF (mass airflow) sensor
Low fuel pressure (leaky fuel pressure regulator or weak fuel pump)
Vacuum leaks (intake manifold, vacuum hoses, throttle body, EGR valve)
Bad gasoline (fuel contaminated with water or too much alcohol)


Sometimes, what feels like a hesitation is actually ignition misfire rather than lean misfire. The causes of ignition misfire may include:

Dirty or worn spark plugs
Bad plug wires
Weak ignition coil
Wet plug wires

Found the trouble codes from a scan we had done a few months ago: P0740 and P0743

"I souldn't be having transmission trouble at 100K miles." - Well, it all depends on how meticulous you are in maintaining your tranny. It also depends on how you use it. My friend got his tranny busted because he was too lazy to put it in N during a red light.

Anyway, since you are already in that stage, you have to bring it to a specialist. Sorry to break it to you this way chief. Im sure your check engine light is ON, get it scanned.

Of course, we can guess like what you did 3-4 years ago and look where it brought you...

Verify first if there is a stored troublecode in your vehicle. To have an idea how to perform it without using a scan tool just check out this link http://www.extreme-check-engine-light-codes.com...
