Very cool to come across this video after I just had the transmission in my 350Z opened to fix the broken circuit that was mentioned in the video. I'm not mechanically inclined aside from smaller, easier access things, but it's always really cool to learn about what vehicles work!
Hello. I have a 2010 pathfinder 4.0. When I put gear in D I have lags. Always about 2 seconds. R turns on quickly and without any problems. Changes gears smoothly while driving. only D has delays. If I increase the engine speed before engaging D, the gear will be engaged faster. what could it be? What do you think? electromagnet or something inside the box? . oil replaced. it wasn't very dark. the oil level is also ok. I will be grateful for your help
Truck i just got will go into gear and pull for a minute..then stop pulling..if i turn it off and wait a couple minutes and restart..it will fall into gear and pull again..when i connect scan tool it says no communication..help
The Saga of my transmission. about 2 years ago I got a code for P1716 Turbine Revolution Sensor. The transmission had a less than 230K miles on it. I replaced the valve body to the tune of $740 for the part and did the work myself. That lasted less than a year, until 12/31/2021 when the transmission would jump into N. I suspect that the high mileage on the transmission meant that clutch pack material clogged passages in the valve body. Managed to get back home and parked it. I got the transmission fully rebuilt on 1/12/2022. Last week 12/08/2022, the transmission threw the code P1767 HLR Solenoid. The same transmission repair shop fixed it under warranty. Apparently there was a faulty ground somewhere on the valve body, and they replaced the valve body entirely. They suggested that it was due to Florida's salty air that corroded the ground wire. I'm struggling to understand how salty air could get into the transmission where the valve body lives to corrode anything in there. I think they said Ground Strap, then that would be outside the transmission, and if so why replace the valve body? The car now has 239K miles Going to re-watch Part 1 and 2 of this video. Seems like the valve body is the weak link in these transmission. Seems to me that putting a TCM in bath of hot transmission fluid for thousands of miles is not the greatest of ideas.
I have a 2005 Nissan Titan. With the transmission, its like when it should take off from a dead stop in first gear, it’s takes off in the highest gear it has. Once I get going a bit it is fine but never shifts. Is that possibly valve body issues?
Not sure if you can help me but My front brake solenoid went bad. so I took out the valve body and replaced the solenoid. Put everything back together and reverse works but when I put it in drive it stalls instantly. I’m guessing it’s trying to go in drive and reverse at the same time or something. I thought maybe the wire harness got pinched but I didn’t see anything when I took it back out. I don’t see anything wrong with the valve body but I don’t really feel like putting it back in and doing the same thing. I do remember touching the gear selector plunger and had to line it up to put the valve body back in but everything looks right. Not sure what it could be
@@JayJay-pm6yf yes. I took it back apart and cleaned everything very good and inspecting everything and testing continuity between the tcm traces to the solenoids. Everything seemed good then I took all the solenoids out. Cleaning them. Carefully put it back together and it was fixed. So not sure what it was exactly. Hope this helps
Question: To replace the vehicle speed sensor you have to crack open the tail shaft right? and does there need to be some silicone between the main body and the tailshaft? I'm replacing the valve body in my G35 and figure whilst I'm there best to put in a new Hitachi VSS.
Hey how are you doing I was inspecting a valve body from a g35 and I noticed where the turbine and intermediate sensor are one of them had a melted top with kind of a slant not a perfect cylinder shape. Would that cause a transmission problem I feel stupid asking as a mechanic but I didn’t know what they were till now
Excessive heat from a slipping clutch can melt the plastic housing but if it continues to work without setting a corresponding code it can be considered serviceable.

Glycol Coolant and water contamination, a common issue and is why they get corroded.
I've been doing a lot of research as I have shifting problems too, 06 G35 automatic with 260k miles!
Turbine Speed sensor code.
@@PlatinumPaladin915 probably time for a full rebuild...250K is nothing to sneeze about. It served you well.
@@PlatinumPaladin915 yep, but not in my case.
Where or is there a spot on the 04 infiniti g35 coupe automatic transmission that says what transmission I have?
@@austinbradley3411 oftentimes it specifies as part of the VIN number.
Great video 🙏🙏

Hi what trans cooler brand external cooler fr a 2009 Nissan titany
Hi
I had a transmission rebuild 2000 miles ago. Nissan 2005. It started leaking oil so the replaced the seal and it still leaking. Please help me

Yo I had this same problem and then I get a new trans from junkyard and put it in today and it still didn’t work. What fixed yours?
@@JayJay-pm6yf yes. I took it back apart and cleaned everything very good and inspecting everything and testing continuity between the tcm traces to the solenoids.

How do i fix a p1774 code? For infiniti g35 coupe?
I replaced the valve body and now the accelerator won’t react?
@@Canwekeepitreal I would start out with plugging in my scan tool.
TY VM REALLY LIKE THIS
I have a infinity qx80 2016 has code p0720 oss n p0500 vss, what can i do to check it?

Yes, you have to crack open the tail shaft. You don't need silicone. There is a tail housing gasket (ADAPTER/EXTENSION HOUSING GASKET).
@@ThompsonAutoTest Well I ended up NOT replacing the VSS. So far so good.
thank you
was this in the 2003 350z’s?

@@ThompsonAutoTest I eventually swapped the transmission and sold the vehicle
Can I switch a 1 plug valve body with a 3 plug valve body?
@@julianoropeza8708 No
Where is your shop? I would really like to send you my transmission
Not having a shop.
My guy using a speed ratchet instead of an impact. O.G.
Need help..you seem to be the man to ask.
