Great video man! Perfect break down of the transmission really helped me out! I had no reverse like you mentioned and my rev clutches were al burnt out
Great video, thanks for posting. I have a 07 Sorento with the same transmission. I have an intermittent problem where car seems to go to limp mode and struggles to rev above 2,000 rpm with no kick down. Happens sometimes but not always. I changed the fluid in the pan (6 litres) and the problem went away for around 4 months. It's now returned and I'm thinking of doing a full flush and filter change. There are three bolts on the filter which have nuts at the filter. Any problems tightening or removing these when changing the filter? would you advise a full flush with 140,000 miles and pan fluid changed twice previous? Appreciate your expert advice! BTW No codes shown with a Foxwell scanner.
ecm inside the transmission ? there can't be any good reason why it's in there. I will take a jatco 3n71b any day of the week over this over-engineered garbage. My hat's off to you for patching this stuff up. The nissan dealer probably would charge much more.
Gary Ferraro To be exact I have a 2005 4x4 and my issue is that while driving for about 20-30 mins it just seemingly goes into neutral. Limp mode is what I told it is called. Then when the engine cools down it will drive normal until same thing happens again. So per auto zone I bought a transmission speed sensor to hopefully remedy the problem but I have no idea where it goes on the transmission. So that’s what I need to know. Where?
I reversed my pathfinder 07 went to put it in drive it clunked loud and went in 3rd gear or second do you know what it could be I already bypassed the radiator months ago bc it failed but I caught it in time what would make it skip first gear
When doing a valve body swap while the transmission is still on the car Can you change the output speed sensor? Or does the transmission have to be removed to change the output speed sensor?
Hello, I have an Pathfinder 08 that starting to act strange when gearing. Car drives smoothly when cold up to 5th gear, that keep slipping from time to time... But when drive car hard it goes into Limp mode cannot go into 4th and 5th..Sometimes the car shudder from 1th to 2nd gear not always. Also when in to Nissan dealer and scanned car, said all gears where slipping. I have no engines light and errors... So what i asking can this fault only be the Vavlebody or do it sound like I need a complete overhaul? Filter was clean and oil look ok, but little bit brown... Had littlebit coolant 2 years ago in transmission and now radiator is bypassed. suggestions would be great and much appreciated.
If there are no codes, you may need an overhaul. Are you sure no codes? By chance does it look like water may have gotten into the trans, earlier pathfinders the radiators would go bad
Have 4 codes, everyone say Gear slipping 2-3-4-5..Dont have the number of the codes have to call again, and ask but the mechanic said these codes where not related to electronic, but engine sensor and gear speed sensor not reading same value. Yes I had bad radiator before but thought I had fixed it by flushing the transmission.
Once the water gets in there its only a matter of time before something happens, if you can, can you get the code numbers and let me know what they are
RE5R05A Code P0732 Gear 2 Incorrect ratio RE5R05A Code P0733 Gear 3 Incorrect ratio RE5R05A Code P0734 Gear 4 Incorrect ratio RE5R05A Code P0735 Gear 5 Incorrect ratio Is the codes im getting... What I understand from you I think I need a complete overhault. Car drives smootly normally from 1 to 4th but sometimes car acting all strange... From my mecanic point of view I would not say friction plates because most of the times car gears fine... but more Valves in valvebody.
Wow the computer is seeing a slip in all ranges almost, have you cleared the codes to see what comes back? so you have an issue in 5th? does it slip going into 5th? Still not liking the fact that water was in there at one point
My Auto 2008 g35x throwing p1757. Removed vb no contamination or signs of metal conductor breakage. There is the front brake solenoid showing no ohms so its done just the one single solenoid. Please help should i buy a single solenoid for $80 or all the solenoids for $150 or complete vb replacement $1k ?
Gary Ferraro, I have a supercharged G35 coupe with this trans. It is slipping in 5th gear (free revving) also it shifts fine going round town but if I am on it it doesn't want to shift. We upped the line pressure and the car would not move itself. We then lowered the line pressure back to stock and it would move normally again. What is the issue? Possibly a bad solenoid, pump,?
3-4 shift is good. I took the input clutch out before and put it back in. Possibly I didn't put it in all the way? I heard a hard clunk when I did and the front pump plate slid on easily and bolted on easily. The only issues I have is shifting from gear to gear at full load high rpm and the 5th gear gone. I have my old valve body, I have a shift kit in the current one. Should I switch valve body solenoids and see if thats the issue?
Correct the 06 Titan came in with po717 code. Found the input drum cracked on the weld of the input drum. I replaced it , full overhaul , new tcm with vb . Had to get the same converter rebuild because no converter core available.
Great video. What exactly did you use to get the last piece out with, the piston. You looked for a tool then video cut to the part being out. Also can you do a build video? I am working on this transmission.
+Robert Ellsworth I used a foot press to depress the springs and snap ring pilers to pop out the snap ring. The foot press i use everyday to disassemble clutch drums. Gary I will keep the rebuild video in mind, i currently do not have one of these units in the shop. What problem are you having? is it a pathfinder? any water intrusion?
+Gary Ferraro Yes a Pathfinder, yes water intrusion. I have already tried replacing the valve body. it still slipped in 4th. I have it all torn down. Most of the frictions are bad. I bought it knowing it had transmission problems. This is my 3rd pathfinder. I got them very cheap because of the transmission issues. The first two I was able to just replace the valve body. Each are still going 20k+ miles later. This one I didn't get so lucky. I work on cars daily but have never gone farther into a trans other than a valve body. I have good service manuals but listening to someone and follow along is so nice. I will try to get that piston out. then its clean and reassemble. thanks
+Robert Ellsworth you have an overhaul kit? when trans filled with water the seals swell, makes it alittle harder to get the pistons out, once you get the snap ring out, try using air to blow the piston out.
+Robert Ellsworth Blow air into the apply port(bottom of case where valvebody sits) see if the piston will blow out, again with water intrusion the seals may be swelled and might be alittle hard to come out, also if the piston pops up on one side use pliers to grab the piston to try to get it out, may have to walk it out.
Hi I have an 05 nissan pathfinder. I believe it is in limp mode/safety mode. I cleared the check engine light code 1767 for the trans Brake problem and it drove fine. I turned it off at a gas station and when I started it up the check engine light came back on and it started limp mode again. Do you think it needs a new valve body? Tcm?
Very possible, but first you have to check the condition of the transmission fluid, every 2005 Pathfinder radiator goes bad and water enters the transmission, may look like a strawberry milkshake. Has the radiator been changed out yet?
No, The valvebody will have to be programmed in order for it to work correctly, a used valvebody will not work, either a new valvebody from the dealer or a pre programmed one with your vin number can be used. Where are you located?
First, make sure fluid looks ok(no water intrusion). P1759 i think is front brake solenoid. The TCM is inside the unit as part of the valvebody, If fluid looks ok, you can drop the valvebody, ohm the solenoid, if it ohms ok, then you nwill need a computer/valvebody, which should really come from the dealer, these have to be programmed now so you cant go used, it wont work. Thanks for watching, please subscribe
Hey Gary, I just bought a used Xterra with auto tranny. I bypassed the radiator so that only the external tranny cooler is being used to cool the atf. Is there any harm in just using the external tranny cooler without going through the radiator? By the way, my radiator hadn't failed yet and my transmission fluid looked fine and operates as it should. I just did a drain/re-fill as well with 12 qts (4 qts each time after driving awhile).
Hi gary. I have 05 nissan pathfinder SE 2x4 and its showing the codes p1764 and p1774 The transmission slips not moving forward/reverse. A mechanic is recomending me to buy a new transmission but i would like to take it some where so they can repair ir what would be your recomendation. Thank you
Hello, These transmissions are very expensive to rebuild. The transmission computer(TCM) is located inside the transmission, for that reason its very hard to get a used one because the computer/valvebody would have to be programmed to the car and that really cant be done. Question, Have you ever had a radiator put in this truck? These are known to go bad and what will happen is the transmission will get full of antifreeze/water. Being the fact that this truck does not move, you probably have a clogged screen from something coming apart. Where are you located?
My 06 Pathfinder will not shift out of first gear when driving, but shifts into reverse just fine, transmission fluid levels good and clean, no smell. Dealer is suggesting complete overhaul but tranny is not throwing any codes and so im inclined to believe it is some sort of sensor issue, but im a girl so no one is taking me seriously lol. Any suggestions would be great and much appreciated.
Hi Carole, Do you have a check engine light on? The TCM on this trans is inside the transmission. When did this start happening? did you have any work done and now no shifting? Have you had the car scanned yourself? where are you located? Gary
Hi Gary, Thanks for following up, nope, no check engine light and accelerates smoothly, just will not shift into 2nd gear. Reverses just fine. I am in the US Virgin Islands, so finding an authorized dealer is an issue, especially since many of the mechanics just want to switch out the tranny without actually considering other options. The car was scanned with a standard ODBll scanner, but I dont believe it could read Transmission Error codes, but in any case there were no stored codes found. Did recently have to change the oil sensor plug but that was it.
Good job
Great video man! Perfect break down of the transmission really helped me out! I had no reverse like you mentioned and my rev clutches were al burnt out
Great, glad i could help and thanks for watching
Gary, Iam a long time viewer of Ur videos, U are very very informative, my questi9n is can U explain how t9 relearn a 45 RFE WITH MY SCANNER
Do you have a snap-on scanner?

Awesome.. Can you post a video putting this particular transmission back together?
will keep that in mind, when i get one in
Great video. You’re the best.
Thank you
I live in New York with that exact same transmission. How do i contact you if I ever needed work done to my transmission?
I have the same trans in my g35 but with a external TCM. What would you advise replacing or upgrading before going boost?
ecm inside the transmission ? there can't be any good reason why it's in there. I will take a jatco 3n71b any day of the week over this over-engineered garbage. My hat's off to you for patching this stuff up. The nissan dealer probably would charge much more.
Thanks, i actually have one of those jatcos on my shelf, havent built one in years
Are the jatco trans in the mid 2000 Nissan Armada? Are they garbage as well?
does a P0500 / P1574 code for VSS on 2003 nissan 350z have anything to do with speed sensor mentioned at 13:10 ?
Good work Gary
+احمد محمد Thank you
Enjoyed your video. Can u tell me exactly where the transmission speed sensor is located?
on the valvebody, it's part of the TCM, If you have speed sensor codes, the Valvebody/tcm will have to be replaced
Gary Ferraro

How many bolts to remove the valve body? Is there a diagram with them marked? Can I do it while it's still on my car?
There are probably about maybe 12 bolts to come out, can you see which ones on the video i take out, can be done on the car
When doing a valve body swap while the transmission is still on the car Can you change the output speed sensor? Or does the transmission have to be removed to change the output speed sensor?
Shouldnt have to remove the trans, if its 4x4 remove the transfer case, if 2 wheel drive, remove the tail housing
Tell the Cust to fix and dump it
Quick question to anyone that knows. Could i use some angled m14x1.5 to an6 fittings to make cooler lines for this trans without any issue?

Generally the solenoids are good, the computer goes bad alot more often, If you have a dead solenoid, i would just replace the one solenoid.
If you wanted to put some fluid over the valves that would be fine, i do that on certain valvebodies
Can you use a Nissan Titan transmission in a infinity QX56 supposedly they do not interchange but I see no difference
Valve body are not the same, internals may be, but i would count the teeth on the sun gears, clutches may have different tooth counts as well

3-4 shift is good. I took the input clutch out before and put it back in. Possibly I didn't put it in all the way? I heard a hard clunk when I did and the front pump plate slid on easily and bolted on easily. The only issues I have is shifting from gear to gear at full load high rpm and the 5th gear gone.

ok, as a test you could try. So this happened after you had it apart and put it back together?
This is a used transmission I put on that was working fine from a donor car that was wrecked.
Hello, i Have same issues , whow You rezolve IT?
Gary. Have you ever had a p0744 code after rebuild? New vb tcm and overhaul plus rebuilt converter. Tcc slip lock up like no lock up
xtremegearheads o-ring on input shaft?
You mean the o ring on outside . Of the input shaft that sits in the converter.? Lock up o ring . Possibly I put wrong one
xtremegearheads possible. Wonder if you have a bad converter. Didn't have this problem before correct
Correct the 06 Titan came in with po717 code. Found the input drum cracked on the weld of the input drum. I replaced it , full overhaul , new tcm with vb . Had to get the same converter rebuild because no converter core available.
There are different input shafts, v6 is one height and v8 is another, did you happen to measure?

Just a update-the number 16 torrington bearing has been eliminated.
The one under the center support correct
where r u located i have code p0717 on this transmission
Im in new york on Long Island, Are you in new york?
Gary Ferraro. nope im in las vegas nv
The P0717 code is a speed sensor code, you will probably need a valvebody/computer to fix your issue

You should be ok, coolers come in different sizes for cars and trucks or SUV'S . just put a larger size on
Great idea. Thank you sir.

Thanks for the hail up from NY. The Ford Dealer will take it Monday so will keep you updated.
Ok, let me know
he must not build many of these transmission ,he is slow
