Thats a really good point, and one I hadn't thought of. I think that the engineers and designers at GM, took this well into consideration, and surely also did some lab testing to get a full understanding of the effects of the exhaust temperature on the transmission fluid. There's probably actually no way that they overlooked it. With that being what likely happened, it probably helps warm up the transmission fluid during a cold start up, because, well if we relied on the torque converter and friction alone to heat the fluid, and also I guess the coolant tank of the radiator. These as well as the exhaust pipe, fresh out of the Cat, each affect the transmissions ability to regulate a certain temp. This exhaust pipe, also had to be tested for the reduction in size that it has there by the pan, and lab testing had to be done to make sure it was not too much of a restriction. As long as our transmissions remain full of fluid they will be ok. Cool observation tho!

@@YANGNIMOG thank you

@MakeItGreatAgain55 good question. It would seem to me, and I could be wrong, NO. The only time that the TEHCM would need to be reset to learn again, would be if new clutch packs were installed, or if anything in the Hydraulic Circuit was disrupted such as the oil pump area, pumping vanes, etc... If you are cleaning the TEHCM and also replacing the Pressure Switches, I would be more concerned that YES, it would be smart to probably reprogram it. But just to remove and clean it like during partial fluid change(drain the pan and replace the measured lost oil with new fluid), I would feel fine with just a reassemble and test drive.

@HVACRServiceTech Thanks for the fast reply! I just did a filter change on a used GMC Denali XL with the 6L80. Check engine light said the 1 and 3 selonids are stuck open, causing shift problems. Simply changing the fluid with a new filter made a world of difference. It is very smooth shifting during the test drive, but now (3 days later), it read that all the selonoids are stuck open while driving the 10 miles into town. We pulled over and parked it for about two hours. When we went to pick it up, it started and drove perfectly and didn't need to trailer it home. Drove it today and it still seems fine but had a little hesitation going from 2 to 3rd. As a precaution, I'm going to change out the fluid and filter once more and clean the valve body and TEHCM as you did in the video before deciding if I need to do a complete rebuild on the tranny. Again, thanks for you time and great video, it helped me out!

@MakeItGreatAgain55 no problem. Did you see my video on replacing the pressure switch films? I think that you should try to change them. I believe in the video that I uploaded, I included footage of me cleaning the actual switch contacts, under the Orange Films. If you haven't had any metal shavings appear on the magnet of the pan, I would wait a little bit before doing the overhaul and rebuild-unless you want to for the experience and it's worth it for you to. But if you're trying to avoid a rebuild, buy the kit off Amazon and change the 4 films, clean the contacts, when you do that cleaning. I'll find the right kit on Amazon and reply here with the link for you. And if the films are old anyways and still sealing, they're gonna fail soon anyways Better to change them now for many reason and the chance that it will fix your issue

Worked out great. I did find the option to reset the adaptations. Shifts so much better. We'll see if it stays that way. My original issue was WOT would shift really late, and under easy driving it would almost skip 3rd and go right into OD.. the person before me must have drive this thing slow all the time. I would've reset anyway after a fluid change, but especially after testing the lock up solenoid was way below recommended OHM reading I decided to replace the part. Only $20 part. I'm very happy with the Foxwell tool. Same one in this video. I would do this reset before having a shop mess with it.. but atleast change the fluid/filter/seal/gasket.. as it says in the tool procedure before reset.. you must have changed some components. Take care y'all.

I worked on a 4l60 once, but I did much more in-depth research on the 6L80. You should educate yourself on the sticker code and how they apply to the GM family. And that info will help you better understand if this can work. Seems the chances are good that they will because of the close year range and the fact that they would not have a TEHCM.

Not too much I don't think

Thanks. You too

@@jesss5588 I usually do move it because I just don't feel like waiting on them to move it so I end up moving it myself and it's faster. But that is only because I want to. It is their job and their responsibility to move it

@@GunnerSentinel does it now? Lol. That's just the way I would do it. You're irritated by literally about 90 seconds worth of time, so much so that you felt you needed to post a comment to let me know. It was a 55 min drive, and when I got the call, I didn't leave for about 20 mins. I made it within the required 2 hr time frame. The 90 seconds is worth my time. You can keep going it your way, it won't irritate me. But that's how i do it and will continue

Thanks man

@@BLUE_COLLAR_REFER oh yea absolutely. Just have to splice them in because the plugs are different good each one.

@I_Lucid_Dreamer aye. Yea that's the call you sent me last night. Oh hey. , I just heard back. I got the offer letter just now

@KenDeltano I'm sure there is a good reason, to make them out of plastic. But I don't know what that reason is. I work in the service department of Hussmann, so idk what goes on at the Manufacturing side of it. You know something crazy?... I have to order Hussmann parts from United Refrigeration. Lol.

That's just the price advertised by my supplier when looked up online by anyone. When logged in the price cuts by 50%

@@HVACRServiceTechwhat app? I do resi not commercial…

@@brandoncorrea511 that is the United Refrigeration Website. Www.uri.com

Dude I swear by the steam gun for fridge /freezer evaps like this. Goes so much faster!! I learned it about ten years ago from an old timer and I never looked back. A hair dryer just pisses me off nowadays.😂😂😂😂

Totally agree you can get a bissel at Walmart for 39$ or Harbor Freight has a Bauer 39$ very portable.

@@harbosonius I use the Wagner for sxs 's as a backup while using the Bissell and it cuts down on time. I had to cobble a Dc fan to clear all the steam so I can see. Especially if I can't get the evap fan to stay on in diagnostics mode.

Why does co2 rupture when low side is closed? Don't work with co2 but have a certification to work on it and never seen this or heard of this.

@ the pressure build up in the case will rise because of the ambient temp. The type K copper will burst if the pressure is not released in time. The only instance we have had that i have heard of is a reach-in frozen food case that burst because the case was pumped down and isolated. This case was also divided from the adjacent cases and the case temp rose high enough to allow the trapped refrigerant to build up high enough to reach the burst point of the copper. The case temp most likely reached above 65 degree

@johnstrh1 it can be alot more at times. Depends on if you work for a major company or not. The big ones can be busy 24/7 so when you're on call it's brutal.

@@ValDominator plz, do explain why you think that...
