Valve Body Programming

[tomo123]

My 06 PM35 stagea is stuck in 4th gear, the mechanic tells me that I'll need a new valve body; however there's no Nissan dealers thay can programme the new valve body to my car. The importer replaced some solenoids in the gearbox when it was imported, they've stuffed up again that's the reason we think it's the valve body. Can't get another box because like before, it needs to be programmed to the car. Is there anyone in Aus that's replaced a PM35 VQ35 auto box.

so its stuck? not in limp mode? no A/T lights up on the dash?

you've replaced the solenoids before and it sorted the issue (temporarily)?

I presume it's in limp mode, when you first turn the car on it drives fine for about 30 seconds then it jolts and is stuck in 4th. The A/T light also lights up on the dash and yes, replacing the solenoids temporarily fixed the issue.

If you need one, why not upgrade it?

That would be in limp mode, there is no point changing anything until you know the code. I assume it's nearly impossible to find a Consult3 unit up there?

I suspect the wiring is hooked up in the shift mechanism or something is shorting out. Similar faults happen when the trans fluid is too hot, so it could be the temp sensor or wiring. Might pay to drop the sump and check the imprters didn't fluck something up.

The car had this problem when it first came into Australia in June. I took it to get diagnosed and fault codes came up solenoids, it's at a transmission specialist at the moment but they've never seen anything like it before. The work is getting done under insurance so don't mind getting a whole new box if it comes down to it.

Fault codes that came up are:

P1757

P1759

Usually it's just bad connections.

Cheers Scotty, I'll have a talk to my mechanic tomorrow.

[tomo123]

Mechanic couldn't do anything so I had a talk to wholesale automatic transmissions. They couldn't help me with my problem but they said they're gonna contact their Japanese associates and see what they can do for me. The problem I'm having is that the mechatronic unit in my box can only be programmed In japan, no Australian nissan dealers or workshop's can do anything.

[Ben C34]

What programming?

[tomo123]

Either the mechatronic or valve body unit needs to be programmed to the car using the VIN. No one in australia can do this

Aus Nissan dealers have the exact same consult 3+ software, sounds like a load of crap to me. I am sure my mate at Dandenong Nissan could swap it over if it was going to be a problem, that's their job after all.

I have changed over a heap of VQ25det RE5 gearboxes without a drama, I didn't expect you would have issues with the RE5 in the series two, worst case you swap the ecu's in the sump? Mechanically the rest is exactly the same.

Did they drop the pan at all, or was it just too hard? Just have to measure a few resistance measurements, the consult 3 shouldn't be required.

[tomo123]

I contacted the nissan dealer here in Darwin, they also said they weren't able to program anything. If you can get in contact with your nissan mate and if it's possible to change the valve body without programming anything that would be great.

I honestly can't tell you what the mechanic has done, im getting seriously pissed off because of the lack of information I'm getting from him.

[scotty nm35]

It takes 5 minutes for a Nissan mech to reprogram, from what i am told. They just chose to put it in the too hard basket I think.

No way a mechanic would disassemble the auto, they would pay a trans specialist to do that usually. Likely you can swap the complete valve body, but if it is indeed keyed to the vin you should be able to swap the ecus over easy enough after removing the valve body again.

Pretty sure the valve bodies are the same as the series 1 M35, with just the ecu grafted on, it's been a while since I did a series 2 shift kit, I don't remember many differences.

[tomo123]

I'm gonna go in and see Nissan personally, sick of calling around and getting half assed answers.

By mechanic I mean a transmission specialist, he's the only one in darwin so gotta go see him if I want anything done in thay area. I'm actually not sure what gets programmed? Does the valve body assembly get programed or something else? Still waiting to hear back from a transmission place in Vic, gonna see if they can get the stuff programmed in Japan then sent over to Aus.

[scotty nm35]

What was the name of the trans specialist down here?

Are you sure it needs reprogramming? They would normally read the data off the old ecu and swap it back on to the new one once the valve body was replaced, using the Consult3, via the OBD2 connector.

[Leroy Peterson]

If talking valve body swap then how is it any different from a shift kit install? Swapping valve body with no programming necessary
