Transfer case in my suburban 2500 makes 2 loud smelling noises inside transfer case. So intense you can feel it on the ground around the vehicle. And then goes back to 2hi. And that’s only when I try to go to 4lo. 4hi works fine. And since that happened I have a serious vibration going up hill and when I turn. When I turn it is accompanied with a clunk. I had my torque converter replaced a month ago. And before that my 4x4 worked fine.

Thanks

Well that explains the pinhole that I found...

AH.....what is our number?.........I don't know either but you made an excellent presentation.

I rebuilt the NP246 on my 2007 Tahoe 5 years ago, about 25,000 Km since. At the time, I replaced the rear case half and installed the case saver. The problem I am experiencing now is the clutch is NOT slipping at all. When in 4wd, the front and rear are locked together pretty tight. Serious tire scrubbing when turning and I can really hear the front diff complaining from the gear train straining. What can I do to get the clutch to loosen up? What can I pour in there to encourage some slip? Yes, it has and always had blue autotrakII in it.

Some 2004 2500HD had the 246 as well. 6.0L 4l80 np246, never had an issue, I had it in auto4 for 17 years straight, never had pump rub, so maybe it isn't a 'will happen' issue, but helps advertising

Do you need to remove transfer case from vehicle to repair pump plate problem?

What other transfer case can I put in my 02 chevy tahoe? Mine is all jacked up and I have bought 2 different ones that ended up being piece of shits as well. I want to put an upgraded case that's stronger in it. I found a guy selling one who said it was a 246 but when I went to look at it it wasn't the 246 and the only tag I could find on it said daewoo I found some part numbers on it looked it up and it showed it was for a 2014 Chevy Silverado and that's the only year it show that it came in. From the outside looks like a better case but hell I don't know. Is there any way that to make it work? Also seen a guy on one of the forms who sells a transmission output shaft that you put in the transmission and you can bolt up a heavier transfer case off the 4L80

Hello good video, thank you for sharing this message, I have a 2004 chevy suburban z71 and the Transfer Case one day released all the oil. I have never used it again .... at the moment it has pots and I will need replacement of the aluminum rear case and the metal plate between the pump and the middle of the rear case to reduce friction and vibration, ask. You have a website to buy everything I need ... Thank you. Tomorrow I will still check well to see if I see everything in the transfer case ...

What if the rear shaft of the transfer case can be moved with just your thumb?

I don’t understand I put the case saver and my snap ring just won’t seat. I push tone wheel but won’t go far enough for rear snap ring to lock-in place

I put the new case saver from merchant automotive in mine yesterday with the rebuild kit

Did the 226's in the Envoy's have this same issue?

Was this issue corrected on 07 & ⬆️ ?

What would make it pop and make noise in reverse long after disengage four wheel drive

Does this include the Hummer H2?

What the chances my 2001 gmc sierra won’t move because of the transfer case it shot ? It had no fluids so I refilled it but now my truck won’t move untill it hits almost 2500 rpm’s in drive or reverse.

Will a NP 246 back housing match a 262

Where can I buy the plate?

Hi from Alberta, Can someone please helpppppp, I have a 2009 Escalade ext awd, I have to sun gears seems like only 1 will fit at a time is there a trick to get the suns on.?

How bad is a trailblazer 4.2 ? Is it real bad to change the TC IN MY 2006 ? Thanks

My 246 works great when key on engine off with it running it won't come outta 4 low

Hi, I have a question, a bad transfer case can make my truck vibrates when I relace the accelerator while driving?.

What fluid goes in it ?

If I could give this 2 thumbs up I would is it possible to see a video of the full rebuild

Could thi cause a vibration at 45 to 55 and again at 65 to 75

Does 243c have this issue?

I don't understand how these metal type transfercase saver are able to do any good. Apart from taking out some slack, there is still metal riding on the housing, except now it it the transfercase saver metal. I have the feeling any non-metal type transfercase saver is the better solution.

Do u sell a kit ?

I have a vibration coming from my transfer case when I put it in 4 wheel drive from around 100 km/h and up , feels like a loose chain , don’t know if it’s something you’ve experience?

I have a borg Warner 4406 that leaks at the input shaft. I have replaced the seal and it still leaks. What else could be causing this?

Can I drive it without the front drive shaft attached? 03 Yukon 4x4 is the vehicle don’t have the money for a transfer case as this is my daily any temp fix?

What would make my truck when I accelerate it Slams on the brakes I've never ran into this problem

How much for a new transfer case

Rebuilt my transmission, transfer case didn’t leak, worked fine, decided while I had that heavy bitch out to break it open and found out the pump had wore about half way through, put the case saver plate in and saved that case

My 02 awd yukon tcase had the pin holes, got the new housing and pump plate. But it leaked immediatly after getting it bavk from shop think i ran it to low now shift fork tabs r melted

What I want to know, is how to easily change the fluid when the case has no drain plug?

What causes my transfer case in my 03 Chevy to slip out when I come to a stop then I go it slips out makes a noise then goes back in

Did one of these in my truck because of same problem, made a really loud whining noise I could hear over my radio...second brand new one I got is doing the same fkn thing...fkn pissd

They could have had areas where to mount that plate permanently with fasteners to the case. Seems like a bad design.

They split the year in 2007

Now if you service the fluids at 60,000 miles,less problems occur.its junk because the fluids were never changed?

not suprise this isn’t a recall 😂

Okay I have a 1993 four-wheel drive Chevy Suburban I like when I go down the road when I accelerate my truck just Slams on the brakes all by itself what would that be transfer case rear end

Talk close

In other words Chevy trucks from 99-07 are terrible because the transfer cases leak and run dry and self destruct ..

Let's go Brandon

Audio sucks

I could barely understand you with all that huffing and puffing going on
