will a P0717 or P0735 cause loss of revers also my Infiniti will move forward in neutral for a short distance then pop in neutral thank you very much video has helped a ton great content !!!!
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?
Hi. my car pathfinder 2010 4.0 when changing gear from P to D or from R to D, there is always a delay of 2-3 seconds when shifting to D. The rest works very well. What can be? Electrovalve? I have new, original oil. Could some solenoid valve be responsible for this? while driving everything is ok. this is most noticeable when it's hot. and when I change from R to Drive. thank you for the information
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.
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
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.
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.
Great video! but I have a question. I currently have this transmission in my 350Z and I am getting code 1716 and the car occasionally does not want to go into 5th gear or shifts erratically. Code says it is the turbine speed sensor. can I replace just that sensor or do I have to replace the entire tcm?
I'm in a similar boat...so here is what I found. there are two sensors ON the TCM (transmission control module - the black plastic in the middle of the valve body ). One of those is the turbine rev sensor....I suspect the one farther back towards the rear. When the spinning of the front sensor is too different than the rear one the TCM throws the p1716 code. Technically they ARE not replaceable. Theoretically you COULD find the exact sensor part , gingerly separate the plastic halves (after labeling and removing the solenoids) and remove and replace the two sensors. Not for the faint of heart. More than likely though your tcm is going out and for whatever reason they don't JUST sell that part. So remanufactured valve body or brand spanking new seems to be the way to go that will include the TCM. I found a remanufactured valve body for my G35 for $740 with 3 year warranty.
update: So far so good with the new valve body, but JUST recently started a hard shift from 1 to 2 when cold, no codes. Once warm works perfectly. Going to replace about 5 qts of transmission fluid with hopes of THAT helping.
@@cfauvel Such a helpful video! Would you generally replace the valve body+TCM for a P0717 code as well? I have a 2007 G35 that decided to stop shifting to gears 4&5.
@@shawnpearson646 I’m no expert … not sure what your code is, but the shifts behavior would be from the valve body. The fluid pressure pushes these valves in and out… if the valve gets stuck it has to build up enough pressure to move the valve and it’s usually not smooth hence the hard shift.. How many miles on the tranny? You can try a fluid flush professionally done where they swap out most of the fluid with new fluid. Or get the tranny hot, open up the pan’s drain plug, catch the fluid and replace that same amount … do that a few times.
Update: the hard shifts ( 2-3) got progressively worst.. on 12/31/21 it slipped out of gear for a split second. Had the transmission fully rebuilt this January /2022 with 230,000 miles to the tune of $3185 ( labor included). :-(
