Really nice explanation of the inner working of the TC, thank you! I just have to correct something. At 6:25 if the 4WD is disengaged, the chain will still be spinning since the front diff and its shaft is not disengaged by the wheels.

[@autotech4103]

You are right, this truck does not disengage the front axels. Good find!!

[@peterunderwood3447]

Another important feature is torque multiplication. And often they are around 2.73:1 ratio. Which is a Little more significant than 2:1 in the example. Great cutaways to show operation.

Great explanation, my RAM 1500 except those 3 modes have also 4-Auto mode which in my conclusion operates most of the time on 2 rear wheel drive (2 High) but can enable front wheels in case of loosing grip(4 High). I drive on this mode all the time which means the chain is not moving by 99,9% of time. Does it mean it is not lubricating upper part of transfer case?

How can you explain, other than "bad input shaft TC seal", the fluid can migrate from a automatic transmission into the TC?, talking about the olds TC with vacuum switch, maybe the vacuum plays a role in the issue?

[@autotech4103]

On those old transfer cases the problem really isn’t the input seal but the vacuum switch. The vacuum switch is suppose to be sealed and not apply to the case of the t-case. The t-case vent gets sucked closed and pulls fluid by the output shaft of the transmission through the input shaft seal of the t-case. Replace the vacuum switch and the other problem may go away without seal change. Kinda a cool automotive problem……

Hey Eroom, the oil pump in the transfer case is used to get oil into hard to lubricate oil such as the planetary gear set and the main shaft.

I haven't seen clutch packs in a transfer case but like anything prove me wrong. Muffler bearings do exist.

I have a 2000 ford ranger that will shift and operate in 2 high and 4high , but when shifted into 4 lo there is a repetitive clunking noise while in 4lo operation . Would you have any ideas why? It is a new to me used truck and I’m slowly learning more about its engineering . So far I have been hesitant to run it in 4 lo to see if the knock / clunk goes away , not wanting to get stuck in 4 lo permanently . Any advice would be highly appreciated .

[@autotech4103]

4low is often difficult to shift into and out of. Make sure the transmission is in neutral when shifting into 4low or creeping slowly ahead. I would guess your clunking is it trying to engage still. Does it drive at a very slow speed when 4low is selected?

I’ll make a video in the coming days as I should have a couple AWD vehicles in the shop next week. Think about it as a differential between the front and rear driveshafts.

What happens when you tow this type of setup and the front wheels are spun freely with the Tcase set in 2H. Does it affect the tranny at all ?

[@autotech4103]

This is a standard trans, the rear driveshaft will be spinning while being towed, the front driveshaft will be turning while being towed. In 2H the power from the rear spinning driveshaft will turn the output shaft of the trans. Because the trans I assume is in neutral the rest of the gears will not spin. The output shaft bearings will be spinning without lubrication so damage will occur. With the tcase in neutral the power will not spin the transmission output shaft

I have some vibration coming from under my feet going around 65mph. Jeep dealership just replaced the transfer case too. So, it's a new issue after they installed it.

If i'm to assume the transfer case they installed was installed wrong or a lemon, what components would be causing vibrations and grinding noise?

[@autotech4103]

Vibrations can come from any driveline components that are loose or damaged but it’s usually a seized u-joint on the driveshaft. If we assume the transfer case is the issue the grinding when you let off could be a loose or skipping chain. I would rule out the driveshafts soon in case they fly apart. A lot of damage will occur when a drive shaft or tcase comes off going down the highway

I'm asking because I test it out alot to make sure it's working and every time I put In 4hi. Only way to disengage fully. I have to back up and turn left and or right and listen for the click to let me know its fully disengage. I read the manual and it says that's normal some times. Why can't it just disengage the same way this example did. You didnt back up one time to disengage. Fyi I did have it rebuilt due to plastic shift fork going bad. Now it has the metal shift fork. Otherwise if I don't back up it whines. I'm only asking because I rarely actually use those buttons. I thought the transfer case is working and moving all the time. Never knew it only works when your using 4hi or 4low.

[@autotech4103]

Correct me if I’m wrong but the 4hi and 4low options are “lock” options. This allows your differentials to lock for extra sticky situations. The backing up is required to get both front and rear differentials as well as the transfer case switched fully. Since your Hummer is always in 4WD it’s not really a downside. If you get stuck you can put it in a 4WD lock position and then disengage afterwards. Good on you for shifting it as routine maintenance. Transfer cases do get sticky, especially in 4WD low.

@@autotech4103 I just watched the video. That was really cool to see. I always wondered how it did it. So basically from what I seen and what you explained is the transfer case just disengages the planetary gear set. Really cool to see. Thank you for answering my question! You earned a sub!

[@rosshunter4626]

Will the chain turn with the front driveshaft when in 2WD? Does it freewheel until 4WD is engaged?

[@autotech4103]

It depends on the vehicle and how that manufacturer manages their 4WD. The easy answer is no, not usually.

[@rosshunter4626]

@@autotech4103 thanks, I have a 2010 Jeep JK that is making a mechanical noise like an intermittent chatter in 2WD when additional torque is applied and was trying to narrow it down. I think I have a bad rear driveshaft or maybe the chain is loose or a bearing is bad. All are expensive so I'm trying to get it right the first time.

[@autotech4103]

@@rosshunter4626 you can remove driveshafts and feel tight, seized or loose u-joints. Start there. Its cheap and easy to diagnose.......

Please explain with central diff lock

[@autotech4103]

Locking differentials don’t have much to do with transfer case. I assume you are asking about locking differentials that you can lock by a switch from the drivers seat. They use mainly air or electric to “lock” your two axel side gears together so they turn as one. Locking your differential takes away from your ability to have wheels turn at different speeds making cornering almost impossible. Locking differentials that are switched from the drivers seat are good for off road machines for gaining traction in a straight line. Differentials with limited slip do pretty much the same thing but do it automatically when you start to lose traction. Limited slip are meant for on road vehicles wanting to gain traction.

Hi mate hope you okay. I really need someone to help me because in my country no one knows what is this and im so sad with that. I have a problem in my G class 400 cdi year 2003 chassis nr ( WDB 463 333 1X14 1219 ) When im about to stop on a trafick or whatever and when gear is about to go from 3-2-1 i hear some vibration in my car and the gear box its not changing gear in the perfect time when u about to stop. Its feels like someone is hitting you from the back. Please let me know how do i find that part . Best Regards

[@autotech4103]

Is this after you are driving at highway speed? Could be a torque converter that isn’t unlocking??

[@SaimirAllaraj]

@@autotech4103 yeah perfectly. When im pressing that gas harder or when im forcing that car there is this problem. Can you tell me what is this please ?

[@autotech4103]

@@SaimirAllaraj not over messages. It needs to be properly diagnosed. Could be control circuits, bad parts, solenoids…….

[@jorangel87]

How about 4auto ?

[@autotech4103]

Ah, good question. This transfer case doesn't have that option but essential it can be achieved by adding a clutch pack that engages when there is a difference in output speed between the front driveline and rear driveline. Similar to a limited slip differential.....

[@jessekling1865]

What engages the 4auto from two wheel to 4 wheel? Is it a solenoid?

[@autotech4103]

@@jessekling1865 most auto systems switch the pressure on a clutch pack in the transfer case to engage the front driveshaft when it has a certain amount of slippage compared to the rear driveshaft. A small motor usually spins to tighten or loosen the clutch pack. But all systems are different. This particular t-case does not have auto mode.

Thats a proper explanation! Tks!

[@pardalbartz]

Some mistake.... You should NOT use 4Lo in manoeuvring a trailer in "tight spot" for most (if not all) T Cases. Reason is 4Lo is (in those majority T Cases) a mode with central locking, meaning both propeller shafts are at the exact same speed. Try a tight turn (say lock-to-lock on the steering) with the central lock. Will either force wheels to slip hardly or damage something.

[@autotech4103]

Sure, turning tight is an issue. I gotcha

[@thisisyourcaptainspeaking2259]

I have manual locking hubs for this specific reason, not automatic locking hubs.
