Done! Sucessful test drive around the block! cleared the coed and it didnt come back.

i put a tiny bit of black rtv around the pan, if anything it helped hold the gasket in place during install.

I definitely had a brief moment of panic once i dropped the valve body, but it was still connected by the wiring to the trans. this thing is somewhat heavy, 15bsl if i had to guess. so i got tired really quick while trying to disconnect the wiring harness. but i finally got it right as i was literally at my last bit of strength. all the while atf dripping all over melol it was not fun!

but, it went back in much easier.

almost 7 qts of atf came out, which was a bit more than i expected. it just kept dripping out. initially about 4.5 qts came out, then another 2.5 after i dropped the pan and started removing the VB.

i had just enough to get it topped off with the same amnt that came out.

Wow man, im always blown away after doing stuff like this, it might be difficult and stressful, but it sure feels good afterwards.

Thanks for all the help from this forum, I literally wouldnt be able to do it without you guys! ok and youtube lol

now, i just hope this lasts for a while. I keep reminding my wife i just saved $4500.00, and that i need new tires... .

drove another 5 miles to Hungry howies!

felt nice, no SES!!

I would say it’s best to remove the retainer clip and push down. That way you just push up when installing the new one. You will have to pull the harness up with pliers or figure out a way to pull the harness up from both sides until you can get the retainer clip on. There are two indents on the harness. Take a picture of how high up the harness is now for reference (I had mine too low the first time and trans fluid squirted out through there).
For mine I just put the gasket that my rebuild kit came with and I just put light thread sealant.

I couldnt get the connection coming up out of the trans body to come loose. so I ended up leaving that whole thing in place. not that it was any easier to disconnect it from the inside either!

So far I have put about 200 miles on the trans since the VB/TCM swap. I did about 50 around town, and then just today loaded up the X with wife and dogs and everything for a day trip to the mountains, went up over guanella pass, so lots of up and down fairly steep grades. trans did fine! It does shift abit different than before the swap, but i suppose that is due to the adaptive learning of the tcm?? either way, it seemed to do fine in and out of O/D, I did have to shift it down into 3rd a few times up long steep hills, but i had to do that before. temps stayed under 210 at the highest, usually around 180.

this was a good test for it. I need to rebuild confidence in my rigs reliability. planning a multi day "overland" trip in sept so i need to gets some miles on it before then!

Welp. P1757 back again. Drove like 2 miles to drop off some donations at good will. I felt it stuck in like 4th after coming to an almost stop. Looked down and saw the ses light come on. Pulled over and scanned it and sure enough. I did clear it and turn off the truck. Upon restarting it's functioning like it should and I drive it back home. Light didn't come back on which is odd. Seems like if the thing broke it broke no?? Idk but now this suck man I really have no confidence in my truck to take it and do the stuff I want to do. I might finally have to replace it. I guess I should pursue a replacement from the valve body seller Street smart. I'm pretty sure they will just send me another rebuilt one. It's not super hard to swap out. But... What confidence will I have that this won't happen again? I'd say I got 1000-1500 miles on it before today. Hard to say as my clock has been reset. Uhh .. in at auto zone now dropping off the starter core. Hope it gets me home!

Did you check the voltage reading prior to installing like I mentioned when you said you had ordered it from StreetSmart??
if not, check the voltage on the solenoid. If it’s off and not like the others ( I forgot what’s the correct reading). Also, check the pin connection that leads to the solenoid, It might be broken. If you do request another valve body/tcm it’s going to be another reman

No i didn't, I said before thats little outside of my comfort zone, maybe ill try it on this next one if i end up replacing it AGAIN.

idk man i may end up just trading this thing in on somethin else, as much as I love my X, im tired of worrying whats going to go wrong next.

not really sure at this point. I drove it like 15 miles after clearing the code and it drove fine.. but even still im just waiting for it to happen again.

 

[mtnbound]

StreetSmart is sending me another valvebody.

the thing I dont understand is how i could get the p1757, clear it and it hasnt come back. anyone ever had this happen before?

 

[mtnbound]

New valvebody arrived today, going to drop the pan tomorrow morning and swap them out in the afternoon, have to do something at noon and it will be nice to let it drip for a while before i get under it.

this time i think im going to create some sort of stand to lower the valvebody onto so that i dont have to hold it up while also disconnecting the wiring harness.

i've got a few spare 2x4's that i think i can make into something that will do the trick.

gotta get some more atf but thats about it.

 

[mtnbound]

I forgot to update. I reaplced it and its been working fine since, about 5-600 miles i think on it now?

the second time i swapped it out was much easier as i knew what i was doing. I used a plastic storage bin to hold up the valvebody while disconnecting the wiring.

lets just hope this time it lasts!

Hey any further updates ? Still working out okay?

 

[Elcid]

Hi I am having the same issue. Where can I get the parts for it?

well, Its been working fine until yesterday. SES flashed and it was the p1757. i cleared it and drove 150 miles through the mountains home and it didnt come back on.

but, now im sure its just a matter of time... so im already trying to decide if i want to replace the valve body AGAIN, for like the 3rd time... or just like replace the whole truck. i think my timing chains need to be replaced, and something is wrong with the steering, either a bad tie rod or worse...

I just took it on a road trip through the Rockies with a good bit of off road driving as well, and i think it was enough to push a few things over the edge.

I also really want to upgrade the suspension, mainly upgrading to aftermarket UCA's. but i dont want to do that if its going to need a bunch of repairs.

 

[mtnbound]

just went for a drive to the store and back. no SES, trans feels normal, but well see how long that lasts.

got under the truck and checked it out, the pass side tie rod end has a good bit of play so thats probably the root of the alignment issue. i think it was on its way out before the trip and it just couldnt handle the off road miles.

that isnt a huge deal. im tempted to go ahead and just get that delt with and worry about the trans later.

 

[mtnbound]

it came back agian, cleared it and its gone but m sure its only a matter of time.

Ironically it came on as i was test driving my truck after working on the suspension/ steering. got that all taken care of and then this reared its head again

 

[mtnbound]

valvebody was sent off to streetsmart( not sure if thats the smartest thing to do AGAIN) but they got it on 6/6 and its on its way back to me today, 6/10. so thats a good turn around, im hoping that since they do alot of these they know what they are doing. im guessing they either replaced the TCM or soldered the one i sent it. they told me that these things are getting hard to come by( good ones) so thats why they had me send mine in, they didnt have one to send me for exchange... something to keep in mind going forward for us that own these trucks.

they did the R&R( return and repair?) for free which is pretty cool as they have a 3 yr warranty on the part i bought from them like 2 years and 10 months ago or something lol, so its almost at that point where i feel like alot of companies would try to deny coverage.

hopefully ill get it back in a few day, get it in with some new fluid and be G2G at least for a while. i swear if i get another Nissan truck its going to be manual, no TCM!

 

[mtnbound]

I got it back yesterday and got it installed. have to wait 24 hours for the gasket maker to seal, which will be in a few hours, then I can put the fluid in and go through relearn procedures.

fingers crossed!

 

[mtnbound]

uh man, this thing just wont end. so i got all the fluid i had, 5.6 qts in it, i think it needs more, i looked back in this thread and last time i needed 7 qts. its not quite shifting how it should be and seems to be running little warm, but im hoping it just needs another 1-2 qts of atf.

it did pop a p1759 after about 2 miles of driving, but that was with only 4.5 qts in it i started there and went up by half qts until i used it all. i cleared the code and it hasnt come back but that obviously has me worried. this all started with a p1757, so i was not happy to see a diffeerent one, p1759, however the description is the same, front brake solenoid.

uh man, i just want this over with. tomorrow morning ill get some more atf in it and see what happens.

 

[mtnbound]

got up to 7 qts in it and its working again! the 1st to 2nd shift is still alittle harsh but i think its the tcm needed to relearn the shift points, its getting better each time i take off from start.

it was hesitating from a stop, but that is gone. no more codes and after research it does seem that the p1759 could have been caused by low fluid pressure.
