Transmission Valve Body
In the transmission of most vehicles there is a hydraulic system which uses specialized fluid which is sent by an oil pump through the actual valve body so it can be used by the bands and the clutches to control all of the gear sets. It is indeed a complex process and before you go about purchasing or installing a valve body for your transmission it will be important to learn all about how this part works. You will also need to think about where you are going to get this part which is essential to the transmission itself, because it can be quite expensive unless you know where to shop. The valve body plays a very important role in making the transmission work and is closely associated with the oil pump which is yet another vital part of all motor vehicles. Once you purchase this part it might be wise to take it to a mechanic or someone who is experienced with doing this type of work. If you plan on doing it yourself you will want to know which steps to go through in order to complete this replacement.
The first thing you will need to do is locate the two spacer plate gasket and identify the several different gaskets which are on the case as well as the valve body gasket. You will then need to set the gaskets on the plate one at a time and make sure that there are absolutely no covered holes at all. Place several guide pans as well as two valve body bolt holes next to each other. It will then be necessary to put the spacer plate directly on the gasket. The next step in this process involves installing the hold down plate and tightening up the three retaining bolts which are left. Make sure that all of the guide pins are lining up directly with the holes and then tighten the plate screws firmly so they are completely in.
You will then have to install the wiring harness and make sure that it is in place. This is an important step which you will want to get right, because if you do not you will most likely have to go back and do a lot of unnecessary work. After you do that you will have to install the manual valve link which is another vital part which helps make the body itself work properly. The next step involves installing all of the steel check balls which are exactly seven quarter inches; you will need to make sure to pack all of the holes with petroleum jelly. It will then be necessary to flip over the valve body and slide the link to the manual valve. Remove both of the guide pins and install several body bolts, putting them firmly into place. Next you will need to replace the O-ring which is located on the lock up solenoid.
Install the lock up solenoid, attacking it to the pump assembly there is a direct connection established. You will then have to clip the two/three solenoid to the harness and shift solenoid b and a, installing each of the body bolts making sure they are completely tight. After that you will need to install both of the lock up solenoid bolts, turning them to exactly 96 pounds. You will then have to install the pressure manifold switch, making sure that the bolts are still tight and connecting all of them directly to the harness. The next step involves turning the valve body bolts as well as those for the pressure manifold switch to 40 inch pounds, 65 inch pounds, and then 96 inch pounds. After you have completed all of these steps you will be officially done with installation.
It is important to make sure that you go through every single step carefully, because failing to properly complete just one part of this process can mean having to go back and do everything all over again. Transmission work can be extremely long, tedious, and difficult so you will want to make sure that you know exactly what you are doing. Each part of this process requires absolute precision and attention to detail. If you are planning on doing this by yourself, it might help to get as much advice from someone who knows more than you as possible. Transmissions in cars and trucks can be very temperamental and give you problems that you did not anticipate, which it helps to learn all you can about them.
