Solenoid Switch Valve Stuck In Low Reverse

Step 1 locate the flow control on the valve a plastic screw which sticks up from the center of the valve and use your fingers to turn it to the right until it stops and then turn it four.

Solenoid switch valve stuck in low reverse.

Cycle the valve to release any contamiation or debris that may have been stuck in the valve. The solenoid plungers are constantly bathed in fluid from the transmission and metal salt from the manufacturing process and normal wear as well as detritus from the friction materials can collect on the plungers and cause them to bind in their bores and fail to function properly. Valve doesn t reverse they assume it is faulty. If the solenoid still does not operate correctly remove the solenoid and inspect the ports for contamination or debris.

This dtc can also be set by the solenoid switch valve intermittently sticking in it s bore under extreme temperature conditions or a worn solenoid switch valve or plugs. Electrical problems can also cause a shift solenoid malfunction since these components require battery voltage to operate. A failed shift solenoid can also cause transmission slippage where your engine revs faster but the car stays at the same speed. Clean the solenoid with compressed air while cycling it.

Transmission code p1776 solenoid switch switch valve latched in low reverse position most of the time it is either a solenoid switch valve stuck internal trans part internal trans failure requiring overhaul or pcm failure. As a result the transmission may not shift gears or it may get stuck in neutral. Nine times out of ten these conditions can be traced to electrical or low on charge problems. In reality these judgments usually are the result of faulty diagnosis not faulty valves.

With the drbiiit check the eatx dtc event data to help identify the conditions in which the dtc was set. Identify these failures by the symptoms they produce. Transmission won t shift gears. Although many homeowners prefer to call their local irrigation maintenance company fixing a valve that is stuck open is a task that anyone can accomplish.

The most likely is the valve body. There are a couple things that can cause that. As all these possibilities are expensive have the proper testing done. One cause of shift solenoid malfunction is if the solenoid itself becomes stuck though a plugged valve can also result in various issues.

If the reversing valve is in the wrong position they assume it is faulty.
