I am currently doing this until i can afford to get a new tranny.hopes this helps



I have the same symptoms. When the slamming occurs, I turn the car off for a split second and turn it on again, and the problem goes away... If this is leaky valves, then why does the problem go away by turning the ignition off for 0.5 second. Doesn't that indicate electrical issues that are the real cause (I don't doubt that the valves are no longer in good shape)???



The harsh shifting in all gears is due to the computer dropping the transmision into limp mode when it detects certain problems. Turning the engine off momentrily resets the status of the computer and it goes back into normal mode until the next time it detects the fault.

The VR valve in the valve body is the root failure in the transmission. It wears in the bore and either sticks or leaks causing fluid overheating and triggering limp mode. Due to design peculiarities, when the transmission goes into limp mode, cooler flow and TC flow is diminished which aggravates the problem.

If you catch it in time, an upgraded valve body will fix it. If not in time, the TC will be damaged and the tranny has to be pulled to replace the TC and often results in the tranny getting rebuilt at the same time.

I'm about 6-7 weeks (3000-4000 miles) into a replacement valve body after having this same problem. I also immediately had the car parked to stop the damage to the TC. Working perfectly so far.
