I own a 07 G35x
last month I got an p1757 code-front brake solenoid
car goes into limp or safe mode...
did my research and concluded that the issue was within the TCM. The circuit or band snapped causing the solenoid not to work.
Went to several tranny shops and they were quoting me prices over 2k
some even advised me to replace My tranny. Lol
anyways i had someone who claimed they knew how to remove my valve body and repair the tcm issue.
To remove the valve body he should have just removed 11-12 bolts. This fake mechanic had over 25 bolts out and the valve body still wasn’t removed.
Story of my life.
Finally the valve body is removed and he gets access within the TCM to solder the circuit.
Install was a mess!!!!
He didn’t even know which bolts went where and I even have 6 bolts from the valve body.
Finally I told him to wrap up and put the pan up because he was lost.
Pan goes up, oil goes in and the moment of truth....
started the car and nothing
P1757 went away, however the car isn’t drivable so I’m not sure if that code will return but now I have a U1000
car wont start with the button
only time the car starts is when I jump the starter and by pass the ignition system. Even with The car started the car barely moves; its very Sluggish. When I put the car in reverse I lose all Rpms.
Anyways I wanna just get a used valve body but I’m having a hard time finding my exact part.
Called infiniti the exact part number is 31705-17X6E RE5R05A
im checking online but I see three different designs for RE5R05A
can someone help me find the exact part I need.
Thanks

 

Afaik there are 3 types of valve bodies, so you could be SOL if you order one you can't return.

 

Im assuming you don’t know which one I need...

 

I don't. It could vary depending on if the lefty or righty was working that day (not serious). You'll need a picture of yours and then need to order it based on that. Valve body stuff is challenging. Internal auto trans parts take a wizard to understand.

 

Sounds like a mess. The U1000 is a can bus communication failure, probably why your car won't start. Something may have been bridged when soldering and hopefully hasn't messed up your car ECU. If the valve body was installed with 6 bolts missing that could be why the transmission isn't working correctly. The valve body is multiple layers and the bolts hold them together to seal, the bolts also seal the valve body to the transmission case for pressure in and outs. Leaking anywhere will keep it from working correctly. The valve body in your transmission (RE5R05A) is pretty hard to install and must be aligned just right with the shift linkage. It is easier with two people. Another valve body tip is there are several bolts that go through the valve body and have nuts at the end. Always remember "Nuts at the bottom" or your valve body will interfere with the linkage and will have to be pulled back apart.
