Has anyone dropped the valve body on the auto tranny? I've been told by a nissan tech that the reason for my hard shifts is because some solenoids on top of said valve body need to be replaced.

 

I am getting an ECU code that is telling me my line pressure valve solenoids are acting up as well. I am going to see if a power flush will solve the problem. To replace the parts (there are 4 solenoids in total that all come together in a pack) it costs $79.00 at my nissan delaership. I don't know what they charge for labor because i will be doing it myself.

 

it is preety simple.

drop the pan, and after you do that, you can see the valve body. i cant remember how many bolts hold it in place but i know there is diffinatly a couple. also you need to disconect the connector that plugs into the valve body. plus it is a messy job casue of all the oil.

 

Have you actually replaced your line valve solenoid pack before? How much did you buy the part for if so?

 

no i havent but i taken out and put back in the valve body.

 

The harsh shift is due to a boost in your line pressure becuase the solenoid that controls the line pressure is allowing ALL of it to go through. Do me a favor if you could: Ohm the wires to that solenoid when you pull it out and check for open resistance. If that sucker stays open, then we auto-tranny owners may not need expensive valve body work anymore to improve shifting.
