The issue could be a bad wiring harness; your stoned friend there failed to test both solenoid plugs for continuity; or it could be your torque converter; though that would sound a different.
What kind of ATF transmission fluid do you use because yours look really clean ?...... And did he put any type of silicone on the gasket or did he just put the gasket on without ant type of silicone gasket seal ?
Nice video. I had an 83 S10 prior to last year when I got a used 2004 Envoy XL. It has the 4200 and the same tranny. It seems easier to fix than my S10 would have been.
Had the same exact issue replaced the whole transmission with one I had from parts car did the same thing. After I went threw it I found information on all data that said to check your timing chain turned out it jumped a tooth advance so top end it would die on its face. Probably don't have it by this time but hope that helps.
I have same issue want to knw should i just buy a new car wont drive past 60 doesn't have money to change all the solenoid parts and find out it was transmission was real culprit
That's impossible for me to tell you. But a good place to start is your transmission pan. If you open it and there are no metal shavings, its probably your solenoids.
Mine is 2 wheel drive, but my guess would be no. Unless there is a safety feature that protects the 4WD system from damage if the the 3-4 gear clutch packs are toasted.
Same thing just happened to my 04 envoy. I noticed about a month or 2 ago that when it shifts gears, it makes a high whining sound before the shift. I ended up changing the filter and fluid but it started doing it again not long after the change. Just the other night when I was driving, it made that whining sound before the shift and just kept doing that. Any acceleration just made the engine rev as if I was in neutral. R D 321 all rev as if in neutral.
@@zaresdad No, everything I tried didn't work. It was determined that I just need a whole new transmission, so the car has been sitting infront of my house for a year now.
@@CarsAndCoffeeKings I actually have a neighbor who came by last night and gave me half for it and supposed to give the other half and pick it up today lol. Only getting $1000 for it, but it'll feel good to get it off my hands.
I don't have an answer for you... but there are more solenoids... one is TCC solenoid... Torque Converter Clutch I think. Did you get any codes on a scanner? I've never had even 1 trans code pop up. I have an 02 ZR2 Blazer with around 173K on it. My eye caught your vid because I'm thinking of getting an XUV!!!!
My sister-in-law has a envoy it was doing the same exact thing as your car my son pulled the pan and filter had a whole lot of junk in it he bought solenoids he saw videos like you are showing I said to my son just get a transmission from the yard I said after we install the transmission I said change the filter and solenoids the boneyard we got the tranny from has a 60-day warranty so this weekend my son and I are going to install the transmission in my sister-in-law's car and see how it goes sounds like maybe your clutches got burnt when it was having the shifting problem I would look into getting a transmission from the boneyard it was $995 I don't know what a rebuilt one would cost probably double that.
send the ECU to get reprogrammed all they have to do is turn off pulse width modulation for the torque converter lockup . it will be on or off and it will stop hunting around .
Well just replaced both solenoids. Found long pieces of metal like some sort of retaining clip or c clip gave out. Other than that it runs great now. 213k miles
My 2013 RAM 1500 has done this for quite awhile now, but when the engine surges like yours i gain speed. I’m looking into replacing the shift solenoid as it gets annoying quickly.
Cars & Coffee Kings I wouldn’t be surprised if mine had that too, but my fluid has been great with no metal or anything in it for the past few changes. Don’t know.
@@CarsAndCoffeeKings did you end up knowing what happend ? I have a 2004 tahoe with the same problem rpm fluctuating and doesn’t go above 30 with out the engine sounding like its being forced
Its a very common issue with the 4L60E. The grime gets built up around the check balls in the trans valve train, the get stuck and dont let fluid get to the gears so your clutch packs burn up. Its a $3500 fix if you take it anywhere. I ended up selling my entire Envoy to Vroom for $2500
@@hank8809 did you ever find out the EVAP issue? I have P0440 code for EVAP and transmission is very weird. Seems like it's slipping, reverse isn't working right either.
Nice video. I have the exact same truck but a slightly different problem. Happened today - going 70mph on the highway and the truck just felt like it went into neutral and will not engage anymore. The shifter works but not difference in going from P to R to D or 1,2,3. Any ideas?
@@CarsAndCoffeeKings Really? But the shifter moves through all the gears. It's not stuck. It simply doesn't engage like a clutch gone dead. Same linkage solution for that?
Yes, that my guess. You can still move the shifter becase the cable that runs underneath the truck and into the console/shifter has either come undone or broken.
@@CarsAndCoffeeKings ok. Thanks. I'll look for a video on fixing it. Is there a part number if I have to replace it? And thanks for all your help and quick responses.
How many miles do you have to be at in order to change your transmission fluid I was told you have to have 300 thousand miles before I can change my transmission fluid is that true
I mean, you can change it as often as you want. But 300k miles is WAY too long to wait. You can google the maintenance for a 4L60E transmission if you want, but id suggest changing it at least once a year or every 15k.
How did you determine it was the solenoids? My truck overrevs 2nd to 3rd and I either have to back off the gas for the shift or go with hevy acceleration and take my foot off the gas and watch for the shift on the tach before I resume.
I watched a few RU-vid videos and that seemed to be my problem. Unfortunately it didn't fix the issue. I saw no difference. It looks like my 3-4 gear clutch packs are burnt out. Also a common problem in 4L60E
My guess was the A and B shift solenoids but after replacing them both to to avail, I think not may be my 3rd gear clutch pack. But that would also be strange because there was no clutch shavings in the pan.
@@CarsAndCoffeeKings I only have first and second. I can only imagine how much they are going to charge me. I love my truck.... but it's just being a money pit for me now
@@vincetetuaniii9732 If it is just your solenoids you can easily replace them yourself in a driveway. I got my parts off amazon for $40 plus $20 for transmission fluid. We have a video of us doing it.
Nope, it turned out to be more expensive to repair the transmission than it was for a down payment on my new GMC. Sold the Envoy, bought a 2017 Terrain SLT
Sounds like your shift linkage. Very common issue, I had mine go out about 10yrs ago. The cable may just need to be reattached then adjusted. I'd check that first. It's not expensive to fix, $20
I have a 2002 and and a 2003 trailblazer and my trailblazer is the same way and I can take my positive terminal off for around 25-30 minutes and put the terminal back on and it will drive and shift perfect til check engine light come back on and it went right back to the way it was so I change the shift selanoids and it runs perfect and strong and I drive it daily but if you try this and your does the same I wouldn't try to take it far because the computer will recognize the same problem in just about 10 seconds or sometimes a lil longer and trailblazers are alot quicker than people think so it will make it threw every gear and its important to test and see because it might have additional problems and like the other guy was saying about the linkage but it's easy to hear it shift or just see if it will role while it's in park and if not try it in neutral and if it rules then. Take the terminal off and give it as much as you can and I'm pretty confident it will move. This is the most common problem of all with these things but the engines are really good with regular maintenance. Mine that I just fixed has 326,000 on it and I can throw rubber down and even shock some vehicles. Hope this helps you and I'm confident it will and they are really cheap and easy to change just not much clearance if you try using the jack that's under the seat. Use a 3 ton and it would be worth the trouble and money to change the filter and put a new seal on it just to cover your ass. Good luck
Yes, its a common 4L60E trans issue with the 3-4 shift. Its a metal check ball thats inside the trans that gets grimey and sticks, causing the trans to not send enough fluid and burning up your 3-4 clutch pack. Its not cheap or easy to fix.
You have the wrong filter , you have the deep transmission pan you need the filter for a deep transmission pan the one you put on was for the shallow transmission pan
Ok, but it's doing the exact same thing, regardless. At this point we've got it narrowed down to the 3-4 clutch pack. The filter fit just fine and the trans doesn't seem to be starved for fluid at low RPM. It just won't shift 3-4. What makes you think it's the wrong filter?
Because I was looking at the filter you was putting on and I noticed that you have the deep transmission pan that why the filter that you put on looks difference from one you took off from the transmission
AutoZoneThis product is a fit for your: 2007 GMC Truck Envoy 4WD 4.2L MFI DOHC 6cyl Part Number: SU9579 -- Transmission speed sensor reports transmission output speed to the on-board computer When not replaced, transmission may not shift out of low and vehicle may experience inaccurate transmission shift points, high fuel consumption
Mine drives like I’m constantly towing something heavy. It just recently started to drag when I turned left and right. I also put it in reverse and it will just slow down like something is stoping me. I replaced the same solenoids and it still did the same thing so I’m thinking it’s the entire shift solenoid set under there (kind of looks like an H) and it’s about $150 online so I am going to try that
