I managed to replace all clutch pistons without any of the special tools. My special tools were a pair of welding vicegrips, a 3" PVC pipe coupling, 2 small bar clamps and two small pieces of flat steel about 1.5 inches by 3 inches by 1/8" thick.....and a lot of thinking. 🙂
literally just based on the back plate view of the valve body at 8:22 saved my butt SO much time and hassle trying to fit all the pieces back together.
Nice job...especially the explanation on how to test the valve body and failure points...TCC valve. Not sure if you gave all or any of the torque specs as you were going through...but would be good if you did. I know all of the valve body is 12ft•lbs
I just finished installing my first rebuilt 6f50, whether or not successful, I hope you can please help. I was careful to make sure the snap rings were in the right location. I built the clutches out using the configuration of the old ones. The one issue I had was the end cap snap ring was really hard to get in. I had to keep the diaphragm lined up to prevent it from trying to get in the snap ring groove. If I didn't have other tools holding it as I went along it would pop out where I had already got it in. Finally, I got it with the help of my brother. The diaphragm was centered, but it seems really tight. I replaced the valve body (Sonnax reman) and solenoid body (Motorcraft) as well, with no programming of the strategy yet. After letting it run for almost an hour and doing the Sonnax recommended shift patterns sitting in my driveway. The shifts felt good, and I decided to see if I could get it to do an adaptive drive cycle, all was seeming ok, with little flare from 3rd to 4th, but not too bad. The road wasn't long enough to reach 50 MPH @2,000 RPM, seems like it may have got up to 5th. I then turned around, after putting it into reverse, which was a little harsh, it seems stuck in 5th or possible overdrive. I came home, less than a mile of driving with it still in this high gear. At home I noticed a noise coming from the Tranny, like something rubbing in a rotation, every time it rotates it hit something, it stops in drive and starts right back up in N or P. I did put a rebuilt F76 reman converter in as well. Any help you may have will be much appreciated. Thanks for the video. Jon
Thanks for the great information tutorial video. You really help me out a lot. I have some bad pressure switches on this 6T75 Gen 1, 2012 Buick Enclave. I have a question. If just replace the pressure switches, do have to replace the solenoid filter plate if I don't touch it? Thanks again...
I'm somewhat mechanically inclined. I've done roughly 80% of all my own automotive repairs and never had issues with my work. Transmissions sorta intimidate me. I'm sure it's something I could apply myself and learn, but good gosh that's a lot of moving parts. I wouldn't have a clue how to put all that back together and I guess that's why it cost so much to have one rebuilt/remanned. I tried to rebuild an old Ford F-100 transmission back in the 90's. Probably considered an easy one, but I had parts strewn over 15 ft and couldn't begin to figure out where all the pieces went. I admire this craft. I think it takes know how and talent.

Hello Sean! Please write how to correctly install the Teflon rings (seal) on the central hub, which contains the drum 3 5 R. I don't have j 466 20-1 20-3 b 20-2 (J-46620-1).

Found this video to be the MOST informational on the 6T70 and valve body. If I end up replacing my valve body or 3-5-R wave plate, this will be my goto. Thank you sir for taking the time to provide this. Was hoping for an opinion. I have an 08 Saturn Aura XR 3.6L. P0752 Shift Solenoid Valve -Stuck On.

Any help with the park-to-drive delay then lurching would be REALLY appreciated from ANYONE.
@Jimmy S Thank you sir. I ordered the diaphragm replacement kit. It was cheap and I can return it if it isn't the issue. Thanks again for your time and the reply.
Chrysler uses 2 wire hall effect proximity sensors for the wheel speed sensors. They toggle between 2 milliamp current levels (6 and 14mA IIRC which makes sense as commercial/industrial gear commonly uses 4-20mA signaling) as the reluctor teeth pass. You can actually hook an LED in series with these sensors and watch it toggle between the 2 brightness levels as the wheel is rotated.
Hello! The training is just super! But there are a couple of questions: 1 What is the force when tightening the threaded connections (valve, valve body)? 2 What can replace the door-ease stick lubricant for piston seating. We don't have it. Best regards, Yura! Ukraine
The valve body bolts and the end cover bolts are torqued to 12 Nm (106 lbs in). As far as door ease, I'm not sure. Sonnax sells what's called the "slippery stick" which is the same thing. Maybe your parts supplier can get Sonnax stuff. Honestly, you won't need it for the pistons in this transmission. You could just use petroleum jelly (vasoline).
@@siuautomotive Thanks! Everything is ingeniously simple! Thanks to your video tutorial, I myself will try to repair the automatic transmission of the transmission (Lincoln MKX 2007 began to slip 94000 miles, 6f50). There are few good specialists in automatic transmission repair in Ukraine. I bought repair kits transtar, transgo, sonnax, wavy disc, made a press.

Best regards, Yurii
First off, great video, thanks a lot for this. But I do have one spot where I'm a bit confused. Near the end, when you're dropping the valve body in, I'm a little mixed up with the bolt lengths and locations. You show 8 of one length, 2 of the shorter ones. You drop the valve body in place, then when you cut to the shot of the bolts all lined up to show lengths, there is already a bolt in place that hold that spring type arm with a roller on the end. You don't really show where that bolt came from, and then in the torque sequence shot its one that is being torqued. Hopefully I'm just a goof and not seeing the obvious lol. Only came across this as I had somebody "help" me on the bench, and now all my bolts are mixed up for the valve body and tecum, so I'm trying to use your video to sort it back out. Thanks again
Thanks for the compliment. Hopefully you get it back together fine. Sorry if that bolt arrangement is confusing. Go to my website that has the autotrans curriculum. Find the 6T70 lab manual and I ID all of the bolts and their lengths. www.automotivetextbook.com/automatic-transmission-curriculum/

Hi dear I have 2018 explorer and control transmission opened with random steel ball I don't know where is place There's 8 holes and just 5 steel ball which one is neglected?
On a 2018 there should be six total according to my service info. The best I can explain is that if you have the valve body with the worm tracks facing up, and the manual valve facing you, the two spots that could take a checkball, but don't, are located in the bottom two spots closed to you on the left side of the valve body. It would be the two spots closest to the lower left corner of the valve body if the manual valve was toward you (6 o'clock position). Sorry, but that's the best I can explain it.

Hello! Please help with information on the operation of the automatic transmission thermostat: 1. How to check its operation (removed from a car). 2. The need to replace it with a new one during the repair of the automatic transmission, or leave the old thermostat. 3. Teflon rings in the Transtar set for 45 mm - 5 pieces and there is 1 piece for 65 mm. Where it is installed at 65 mm .. Tell me what should be the correct dimensions (on the outside) of the Teflon ring after replacing it with a new one using the installer on the hub of the rear cover. I will be very grateful for your help. Regards, Yura! Ukraine
Hello Yura, regarding the thermostat, I think I wouldn't worry about it if the transmission didn't have any overheating issues and the transmission failure didn't involve the torque converter failing. If it did, I would replace the thermostat/bypass assembly. Once you get the transmission going, the bypass will open when the transmission warms up, and you'll feel the lines carry warm fluid to the cooler. That larger seal is probably the stator support to torque converter seal. Regarding the outside dimensions of the installed seal, I don't have that information. Just make sure the seals are compressed enough to fit back into the end cover. Then keep the cover on the seals until you are ready to assemble the parts into the transmission. If you don't have a seal resizer, you can use your fingers to squeeze them into the grooves. Then you can wrap something around the seals and use a hose clamp to squeeze them into their grooves a bit more. The teflon seals have a memory, so they'll stay compressed for a bit. If you do one at a time, then try the end cover, you can get a feel to see if they are grabbing the end cover with a little bit of tension.

When upshifting and rear wheel lock during upshift could that be a clutch not overrunning?
can you replace the wavey plate with a regular steel plate to eliminate brakeage of the wavey plate?
I've replaced the TSS and now have developed a leak from the sensor. Can I replace the o ring on this sensor?
