P0755 shift solenoid valve b
I have a p0755 which is shift solenoid b in the transmission valve body inside the transmission oil pan, my question is has anyone here this issue? And is it possible that the solenoid is simply dirty?
Or is it most likely needed to put a new solenoid in there, I don't mind changing the part but it's the cost of the actual part itself that makes me wonder if cleaning it would do the job

It can be just the solenoid or the valve sleeve getting stuck. The best thing you should do is check and see if your car shifts through all the gears,with this function you are most likely to run 1,2-3,4 or 1,2 or 3,4 if I remember correctly the 1,2 are the a valve and the b valve is 3,4 only.

You can test the resistance of that solenoid on an external connector.
http://maxima.theowensfamily.com/tsb/NTB98-043.pdf
Disconnect connector F42 and measure the resistance for solenoid B. The resistance range is 10 to 20 ohms. Connector F42 is loacted behind the parking pawl.
Solenoid B: Pin 1 and GND
If it doesn't measure within that range then replace the shift solenoids using this thread.

They cost less than $90.
If it measures between 10 to 20 ohms then that solenoid is fine.
As suggested add in some trans treatment then perform a non-pressurized 10 quart flushing. You'll find details on that flush in the Fluids & Lubricants Forum (how to flush ATF...)

Thanks for all the help so far everybody,
one question though, is it a better idea to go with the new $90 kit or simply the original kit which is literally $405.00 which I found out abt by calling the dealer today,
Are both the same exact parts?

They're the same. That upgrade kit is collecting dust so they're selling them at clearance prices. I inserted them 3 years ago along with a Transgo shift kit.

I got the new part in today, I'll be installing today as well, just gotta study the procedure a lil bit
Looks pretty straight forward only thing that's tricky is the manual valve shaft thing,

I got everything out now I'm going to be installing it back in, but a question where does that big spring go on the control valve assembly it came out during removal now I don't know where it goes back in,
Can you tell me where to place it?

For that small spring view the top right figure on page 4 of this manual
http://maxima.theowensfamily.com/tsb/NTB98-043.pdf
That small spring is seated behind the Line Solenoid. On the far end of the main VB there are also 2 mid sized springs with ***** on top for controlling the pressure.

Thanks for that, I only had 2 springs come down which were the big large one and the one after line solenoid was removed,
1 other questions, since I didn't remove the transmission from the engine I will have to hold the big spring into place wile reassembling the control valve assembly,
What's the best way to hold it in place while securing the vc assembly back? Simply place it onto the cv and hold it steady in place and tighten the bolts hoping it went in securely ?

Btw any certain way to position that bracket with the bolt for line pressure solenoid? Kinda looks weird when I put it back on, it doesn't go in between the line solenoid right?
#16
When I first disassembled a VB that bracket location got me stumbled.

How many quarts did you fill back in after this install looks like to me it needs abt 10

I must have stared at your pic from another thread for about 10 mins and saying to myself wat is the purpose of it being positioned like this? Because if you see the fsm http://maxima.theowensfamily.com/tsb/NTB98-043.pdf it on page 4 it shows it as if it's literally going through the solenoid

With the pan and VB dropped I only added ~8 quarrts. The TC holds a few quarts of ATF.

The tranny takes a total of 16qts,torque converter takes about 2qts,the rest is on the tranny. The little spring your talking about that goes into the spot where the solnoid goes. The vb has two little metal ***** to that go in the valve sleeve. That's if they didn't come out while you were fiddling around with the other things.

As seen in the bottom left of that photo is an arrow pointing to that loose corner bracket.

I mean't you will need 16qts doing the powerpurge flush on the tranny. The drain and refill you will just need 10qts. The cooling lines and the inner tranny lines take a chunk of the fluid.
