722.6/Nag1 Rebuild, The Valvebody

[@imt5802]

Well done Gary, I could just sit here and watch (the Bob Ross of Transmissions), eat Dinner and still learn something! It's just amazing to see how you're doing your thing, taking things apart, clean them up, making them better than before, some grease here some O-Rings there, using torque that feels good, and "just like magic", done is the Valvebody! Thank you very much!

[@claycoates5056]

I have done many transmissions and i still get freaked out whin i do a valve-body I had a bad time with one about thirty years ago and found the problem but still get the willy's going them i do not do them all the time just as a hobby to help others and like all other things whin done gives that feeling of wonderful satisfaction Thank You for your time to share your know how

Hi Gary, amazing video. Could you please give me more info about this red can sprayer?? Is it custom made o buyed ? I'm seeking for some like this a lot of time. Only saw a few little refillable bottles but too much expensive and last only a few seconds. Thanks in advance!

Hello Gary thanks for your help! What kind of stone is that you use?

[@GaryFerraro]

Think i got from Amazon, fine one side course other side

[@1stedfast]

Thank you for sharing your knowledge. What is the blue top selenoid from Mercedes do or change, I'm looking to get a firm shift next time I drop the pan

[@GaryFerraro]

blue tops are for the E55 AMG only i believe, you can't replace them if a brown top is there. Firm shift maybe a shift kit

[@dzevadcosovic4878]

Hello Gary, on the basis of which criteria do you decide to disassemble the aluminum part? Why don't you simply change the plastic part itself? What should happen to decide to disassemble the aluminum part as well, it seems a bit complicated?

[@GaryFerraro]

I always disassemble the valvebody to clean it and make sure all valves are moving free

[@dzevadcosovic4878]

@@GaryFerraro Hello Gary, I didn't expect a quick reply, thanks for the reply. I wanted to ask you for another answer from you. Auto diagnosis Autel 806Profi showed that I need to change the electrical part of the automatic transmission 722.6. But while waiting for the ordered spare parts to change it, I noticed the car in the parking lot after ten meters, when I stop, it won't move forward or backward. At that moment I can't give more gas? When I turn off the car and wait a bit, I can park again. My question is whether it is the result of an electrical fault or, something else? May I embark on an adventure with the car to drive slowly 4/5 kilometers to the garage This time I will give up, from checking the hydraulic part of the gearbox. I will wait for another chance. But all praise for your work, you very clearly explained the problem of the automatic transmission. Now we too can be masters of the automatic transmission 722.6. Best regards Gary,

[@TigerRacingProducts]

I have a 2-3 flare and replaced control valves with a sonnax kit with orings. The issue still exists. Is there something else that controls the pressure or movement of the 3rd clutch pack? Great video BTW. Thanks!

[@GaryFerraro]

There are the solenoids, you also may have an internal problem

[@TigerRacingProducts]

@GaryFerraro ok. Thanks! I'll check them out. Appreciate the info and videos. 💪

I like your videos. I’m working on a w5a580 assuming it’s the same transmission. The vehicle is a Jeep grand Cherokee. The tcm was stuck in limp mode and noticed when start it up the voltage to solenoids went down to 2.6 volts. Changed the tcm, it’s shifting now but when it gets up to around 55 it acts like it’s in neutral and stops pulling until it slows down to around 30 then it pulls again. Looking at live data from my scanner it shows 3/4 solenoid set even when it’s idling in park. Do you think it would be in the valve body?

[@GaryFerraro]

are there any codes present when this happens? does this stop moving when hot?

[@jeffreyroe3176]

@@GaryFerraroit’s throwing code p0730 incorrect gear ratio. This problem occurred when my daughter was driving it was stuck in limp mode, wouldn’t go over 40mph. I scanned it and said p0743 tcc solenoid circuit. I checked live data in original tcm and noticed it wasn’t sending 12 volts to tcc solenoid. I changed the tcc solenoid and the tcm. Now checking live data it shows 3/4 solenoid set as soon as I start it up. While driving it will get up to around 55 but then it acts like it’s neutral and seems like there’s no action from gas pedal until it slows down to around 30 then it will start pulling again.

Good morning Sir. I have been watching one of your videos that details the disassembly of a Ford C6 transmission. Quite honestly I need some advice from you. I’ve owned my early mustang 47 years now. I recently had to replace the gear selector shaft seal. The problem I have is confusion about how to position the park prawl actuator rod to then be able to reinstall the valve body. I did take photos prior to removing the valve body but I imagine those initial pictures didn’t focus enough on some of the details of linkage configuration. Also I noticed that the band wedges that hold the band together, one side, the side where the band adjustment screw is was not positioned properly so I loosened the screw and repositioned it as it should be. Question is how do you feel about torquing the screw to about 10 foot pounds then turning the band screw out 1 1/2 turns? Should there be slight slack on that wedge when it’s adjusted properly? I appreciate your input thank you

[@GaryFerraro]

Thats fine, but after the 1 1/2 turns out make sure the band is not to tight, check that before you lock the nut down

[@arnaudsaulzet1278]

Bonjour, a combien de Newton vous fermer la valve body? Un grand merci.

[@danmcmahon1656]

Gary - I have an opportunity on a NAG1 and the owner says a mechanic told him what's causing limp-in mode is 'Transmission Relay Sensor. It's the sensor that tells the car which gear it is in.' Does that sound like conductor plate? I assume this can be done with the transmission in the car? Thanks

[@GaryFerraro]

do you know what the code number and definition is? I would like to know that

[@hoangan5262]

After you replaced the conductor plate. Did you need to reprogram the system?

[@tonydiesel3444]

If it went in to limp mode

[@brandonharber2439]

Are you calling the lock up solenoid the same as the TCC solenoid?

[@tonydiesel3444]

I've already done transmission service and new conductor plate transmission works fine but every once in awhile when you come to a stop it will seem like it is in between gears and not want to shift I got the fancy kit when the conductor plate was replaced the O-rings and screens were replaced as well any idea what this would be

[@1stedfast]

adaptative software

[@stormrider01]

In my case the lock up cellinoide was changed but I still have a jerking when the convertor clutch lockes up. What can the problem be? I chasnged the whole oil and my shiftings are perfectly smooth.

[@GaryFerraro]

could be converter or maybe problem with valvebody. Any codes?

[@PaulieFein]

What's the purpose of flat sanding both pieces of the VB? Is that necessary if you're changing a conductor plate?

[@GaryFerraro]

Not if changing plate. I do this to try to avoid cross leaks

[@dzevadcosovic4878]

@@GaryFerraro I do this to try to avoid cross leaks?Can you explain that a bit? When the plate is changed, how do you know that the other parts also have to be disassembled in order to sand them lightly and clean them. What is it criterion for that, When changing the plate

[@akandwanahoraymond7581]

Hey Gary. NAG1 in jeep commander with a 3.73 axle ratio. I have changed TCM, whole transmission, FDCM and conductor plate but there still remains a P0734 'incorrect gear ratio in 4th'. Any ideas? Could it be a solenoid issue or electrical connection? Do I need a specific VB from a jeep and not MB? I did change the rear speed sensors too since output speed is read off them. Note; there is slight bump when I engage Reverse.

[@GaryFerraro]

what happens on 3-4 shift?

[@akandwanahoraymond7581]

@@GaryFerraro in liva data, i observe that it will engage 3-4 successfully for about 3 cycles. It goes all the way into 5th. A down shift to 4th after that is when i feel some flares in the transmission and it goes into limp mode. After that, 'current gear and target gear indicate SNA or signal not available'. When I get to traffic lights or some halt and try to set off again, the revs are high and the power is very low (probably stuck in gear 3 and slipping). Turning car off and starting off again resumes normal transmission and cycle repeats itself .

[@akandwanahoraymond7581]

In addition; freeze data suggests that the trouble is triggered in 4th gear. There is no DTC of any solenoids indicating faulty. However, once i saw a p0778 while resetting ecus. It's only come once. I have been trying to fix this car for 2 years and used scan tools every time. Given that it appeared once out of atleast 50 diagnostic tests and never returned, I was curious if there could be something I'm missing along those lines.

hmmm not sure, they come in the overhaul kits but not sure if sold separately

[@PaulieFein]

I noticed at 25:03 you tore open a bag of O-rings for the shift solenoids. I looked online for such a kit but with no success I just replaced my CP using this video as a guide, but my transmission is still coming back with the same codes, plus now the converter seems to be slipping. I was meticulously clean too, but I did not split the VB, just swapped the CP, and both Line & Shift Pressure Solenoids - Blue Tops (updated part number). Do you think dissembling the VB, and thoroughly cleaning, replacing O-rings, and possibly the Lock up solenoid might be necessary?

[@GaryFerraro]

what code are you getting? did this come through with blue tops originally?

[@PaulieFein]

@@GaryFerraro P220A, and P2200. These were read using Star. I did have the codes with the old blue tops in, same codes returned now with the updated blue tops. And now the trans slips if I goose it and goes back to limp mode
