How to flush the automatic transmission fluid & change the filter in a GMC Sierra, Silverado, Yukon

[@guillaumeroyer9366]

Thanks man, this is awesome. I flushed my transmission like a pro today after watching your video. This is gold.

[@HouseDoctorRay]

Glad you found it helpful.

[@electofiguerasjr6312]

I just discovered your U-Tube channel this weekend and watched about 10 of your videos. I liked them all and appreciated the amount of detail you put into explaining things. I especially enjoyed the tip on flipping over the adjustable wrench seen in the toilet video to change it from standard to metric .LOL Keep up the good work.

I purchased a 1998 Chevy suburban and it has bn previously used fluid.they did not change fluid. This transmission is over filled at least 5 quarts is you're process gonna work? The same way ? Out with the old In with the new?

[@HouseDoctorRay]

Sure but you should still drop the pan and change the filter when you're done. You could at first let it run until you see air then start putting new in until it runs clean. Just don't let it run dry too long.

[@happytrails1963]

Thanks for video! 151k miles on 04 cateye and would like to try this.

I bet this is much easier on your valve body than the other methods, also should I change my shift solenoids

[@HouseDoctorRay]

You'd have to ask Brandon Sloan.

[@NowTheVoid]

I see some people plugging to the actual metal line versus hooking to the cooler, is there a difference?

[@HouseDoctorRay]

Not really, it's just easier on the newer GMs to use the adapter because of the shape of the line ends. The only substantial difference is the way I did it the cooler gets flushed but there is minimal fluid in there.

[@NowTheVoid]

Watching the whole video was worth the "German torque" joke. Goodntite

[@mikereeves7827]

What is the purpose of the adapter? Im assuming it is a plug and do you remove it when putting the hose back?

[@HouseDoctorRay]

The adapter is used to connect the clear hose to the radiator. The upper port of the radiator is the return to the transmission. Dirty fluid gets pumped out as you put fresh fluid in.

[@mikereeves7827]

So the fluid comes out of the radiator not the disconnected hose?

[@HouseDoctorRay]

That's correct and GM has quick disconnect lines that require an adapter.

[@carsunlimited4397]

Just bought a 03' Suburban 1500 with 242k miles on it, I don't have any service history since it was an auction car, it runs and drives but idk should I change the transmission fluid? Any advice?

[@HouseDoctorRay]

Right at the end of the video a link will pop up on the upper left of the screen ( 3 cups of fluid). Watch that and decide for yourself. Mine was just over 200K and never been serviced. I only did occasional light towing in those 200K miles and my fluid wasn't burnt or dirty. My opinion is changing the the fluid can never make it worse but I'm just some guy on the Internet. Any GM dealer can pull up all the service records if anything was ever done at a dealership.

[@irishuwould5185]

Instead of sucking the old fluid out you can just run the truck and wait till stops pumping and turn the truck off right away

[@HouseDoctorRay]

OK. Now I just want to smack myself. You're right.

[@sdfljkasjdsdf5371]

You mean, run the truck without putting new fluid in at the same time, until all the old fluid is out?

[@irishuwould5185]

@@sdfljkasjdsdf5371 you can do it either way. All at once but you gotta be quick or just shut it off then refill and do it again. I’ve done both ways. If I have a helper I’ll do it continuously, they just hand me the fluid.

[@moycorral7870]

So I can change my filter and drain the old oil and seal it back, turn it on without adding any new oil till all the old oil comes out turn it off then add all the new oil?

[@HouseDoctorRay]

Better to run it with the old filter in it. Let it pump the old fluid out and add new as it goes down. Then put it in new filter and fill until the level is good and the fluid isn't foamy. Drive easily and recheck fluid level.

[@jamesmayo35]

I did the filter and replaced what come out in the pan at 110k. I am at 210k now and think I will just swap out some fluid with the syringe. If it is still going strong at 250k I might give it another filter.

Still going... It should blow up any day now. Seriously, I did a flush on a '15 six speed at 130K, it's now at 175K and probably due for another flush. The one in the video doesn't get driven much but it's still fine except for the battery dying from lack of use.

[@michaelgreene5525]

Would it be ok to suck fluid out of pan then drop pan change filter then do the flush or does it need to be done in this order?

[@HouseDoctorRay]

The flushing gets the old fluid out and it's difficult to get the right amount back in. It's best to drop pan and change filter after so your new filter doesn't get dirty and you can get the proper amount of fluid in the transmission.

The gears on my 2003 gmc sierra are slippery after doing this, the gears can't connect anymore

[@HouseDoctorRay]

Put it in 2wd, jack up rear wheels and chock the front wheels. Start the truck and run the shifter through all of the gears at idle. Recheck your fluid level. Are you sure the filter was fully inserted and the shifter cable is on? If your fluid is foamy you have to wait until the bubbles dissipate before you try and drive it and get the fluid level right.

There will be a port near the top to add fluid but you'll still need to access the inspection port on the side to make sure the level is correct.

What I am calling the vent has a rubber plug in it on the Rt side of the transmission at the top of the heat shield for the exhaust. Is this the port you are talking about and where is the inspection port located?

Can changing gears during the flush F-up the transmission? That’s what this idiot did… I let a few quarts drain out in a few gears with the e-brake applied. My 2005 Sierra won’t move in drive or reverse now. I also didn’t find that fancy attachment you had to attach the hose to the radiator for the flush. I just had a 3/8 hose to shove into the radiator fitting to do the flush.

[@HouseDoctorRay]

This is sketchy and try at your own risk: Warm it up and check fluid level. Shut it down chock front wheels. Put the rear axle on jackstands. Start it back up. At idle put it into low gear. If the wheels start spinning, run it through the other gears at idle. Make sure to hit the brake before going into reverse or park. Put into park and check fluid again. It's possible the filter wasn't inserted fully.

[@theroach02x]

End result was great! I just had to top off the fluid. Someone said the transmission won't engage from park to reverse or drive if fluid level is too low. needed 7 more qts of trans fluid. Truck runs as good as always at 290k miles. I put almost 6k miles on it since the flush. The flush would have gone a lot smoother if I just had the radiator attachment you had, the clear hose & a 5 gallon bucket instead of the oil drain pan I had.(something clean & specifically for that purpose)That way I can clearly know how much fluid came out. For anyone doing this for the 1st time.. all those parts are probably at Lowes. Clear plastic hose for sure & I know I saw the correct 3/8 attachment that may fit the radiator & tube. The 5 gal bucket was a cheap there. My worksite was a ghost town so I took my truck for a spin, cycling through all the gears once I was comfortable with the fluid level. I did that without pressing on the accelator at all.. that way fluid will cycle through the gears of the transm before driving at high speed.

The return line from the radiator is what lubricates the transmission, so you ere doing damage which is not smart. Rethink your strategy.

[@CharlieAtkins]

You are 💯% correct, and people just don't understand this is NOT how to flush an automatic transmission... Running the unit without return fluid going into the lube circuit will cause damage to the bushings in the transmission and do more harm than it's doing good... If you don't have a true flush machine then just drain and fill. 👍

[@Califamilymanprepper]

So if you have 2 people adding the transmission fluid into the vehicle while it's running. One thru the dipstick, and one on the return line. Won't that take care of this concern. Or not. My transmission gage runs hot when I'm towing my trailer, so I'm trying to figure out the easiest way to fix the problem. Any ideas would be much appreciated

[@HouseDoctorRay]

If you have a GM there is a thermostat on the side of the transmission where the lines hook up. Like anything else they can go bad. If you don't already have one you should also add an air cooler after the radiator if you're towing. SureCool is pretty popular mod but I have no experience with it.
