MIL Illumination - DTC P1776 Solenoid Switch Valve Latched in LR Position
The solenoid switch valve is not part of the solenoid pack, but rather it is located inside the valve body. It will require a new solenoid switch valve, and possibly a new valve body it the bore where the valve resides is worn.
Unless you have rebuilt valve bodies professionally, I dont recommend this job being done at home. If not rebuilt precisely, and there are hundreds of parts inside the valve body, your transmission will not move, and in fact can be damaged.
The valve body is inside the transmission itself. If the bore is worn that the switch valve seats into, then the valve body will need to be replaced, but all the little springs and ball bearings, and other parts that are housed in the valve body have to be transferred to the new unit. This is very tedious and exacting. Even the bolts that hold the valve body to the transmission are different lengths and if they are not put back in the correct position, the transmission will fail. This is not, I repeat, not a job for a weekend or backyard mechanic. As a matter of fact, not many general mechanics at repair shops will touch a valve body. Most shops have at least 1 transmission specialist on hand for doing these type of jobs.
Just to verify, I can replace the solenoid switch valve but if the bore is worn the valve body needs to be rebuilt which needs to be done by a professional.
Yes. In order to replace the switch, remove the transmission pan, remove trans filter to access the valve body. Disconnect the switch valve and pull switch valve out. Install new switch valve.
If new switch valve is loose inside the valve body where it seats, then valve body needs to be replaced and all the parts transferred from old one to the new one.
