Some say you can shift to & from Hi & Lo while rolling but some say you must come to a complete stop. Which is right? It really is a pain coming out of a mud hole in Lo and having to stop to put it in Hi. Also, I was told its ok to put in 4WD while rolling just as long as your not on the gas. Is that true for the diff. lock as well or do I need to stop for that too?

I also have wondered about shifting from Lo to Hi or Hi to Lo while the machine is moving. I did try it only once with my 2001 kodiak and it did make one **** of a grinding sound so I never did attempt it again. The noise that came from the kodiak sounded like the gears would not mesh untill I fully stopped, then it went right into gear easy. I have never tried it on my grizzly for fear that I may ruin something. As for shifting on the fly in/out 4X4 I do it all the time on the grizzly and the kodiak without ever any problems. I don't know about the locking diff on the grizzly for I have never tried to engage it while moving. Hopefully someone here can give you some solid answers and I wouldn't mind knowing myself.

Don't think you can shift between Hi and Lo while it is moving. I know even if you have the rpm a bit to high shifting into forward or reverse it is not a smooth transition. I would not do it. Now for going into and out of 4x4 I do it all the time at a slow speed but do not do it while spinning and the same goes for diff-lock.

DK,

So you can engage the diff lock while moving slowly? That's good to know and thanks. I also agree that trying to shift from forward to reverse when the idle is high is not good at all. The kodiak was exactly the same way trying to shift gears when the RPM's were a tad high. I do know when I shifted the kodiak from Lo to Hi that one time, I thought I was going to die whenever I heard that grinding sound and it was LOUD!!! I wont ever be trying that stupid move again! Live and learn as they say. Thank God I didn't ruin the kodiak.

First of all, you need to know that when you stop, the clutch is disengaged, (it activates with syntrifugal? force) thus essentialy disconnecting your motor from your tranny (driveline wise). At this point it is ok to shift to and fro low & hi because your tranny is not spinning it's internals, they are idle. You can look at it as a 2 speed manual tranny, because really that's what it is. You just dont have a clutch lever to disengage the motor from the tranny at speed, nor do you have syncros. Same said for shifting from forward to reverse at high revs, if the revs are high enough, it will lock your clutch, and at that point, you are trying to mesh a spinning gear (because your clutch has been activated) with an idol gear (because you are not moving), you need a low idol to disengage the clutch. I hope this helps, and sorry it's tough to explain! As for 4x4, there is an electronic actuator for that, and as long as there is not much force (torque) being applied, you should be fine. Now in the same breath, I would not recommend trying that while your rear tires are slipping and fronts are not.... you want your tires spinning the same speed.

I have shifted several times from Hi to Lo and Lo to Hi while moving. It can be done and you do not get grinding like described above on the Kodiak. It is not always easy, especially if you have any kind of load applied. You pretty much need to be coasting and at a pretty low speed. On my recent trip out to the Rocky Mountains my machine was not running well and I was constantly shifting to be able to drive around the bog I was experiencing. You can tell when you try to move the shift lever if it is going to be possible. I would compare it to shifting a manual trans on a vehicle without pushing in the clutch. You need to be at the right speed and load for it to occur smoothly. As far as 2x to 4x a way to get a feel for that is to go from 4x to 2x with throttle applied, it will not release until the load lightens ie: let off throttle. You can watch the dash indicator to see the transition occur. I also thought that Diff lock would not engage while moving. Again if you look at the dash indicator for conformation of engagement or disengagement I have not seen it engage while moving. That has been my experience.

Thanks for the advice. That's what I figured but wanted some reassurance.

i just joined and was wondering the same thing...thanks

I can tell you that if you shift from high to low while moving its the same as doing it in a 4x4 truck...it causes a lot of unwanted stress on the moving parts in the diff and the tranny. You have to think of the spinning gears that have to mesh together...if they are both moving the probablity of getting a 'clean' meshing while they are moving is very slim. Yes, you can shift it on the fly from 2x4 to 4x4 or high to low, however, by doing this you are essentially smoothing and grinding the teath of the gears down in the diff (hence the grinding noise). I guess in a very diar situation I would consider hiting the diff lock while moving but would know that it could cause damage to the tranny or diff. Its just like the risk you take by installing larger tires, jumping a 600lb utitilty ect...It can be done but at the users own risk.

marine,

i absolutely agree. i generally stick with a slow/no throttle swith to 4wd and always stop before diff lock switch. have not had any problems with this method. better safe than sorry...

i posted a new thread on the site about my front diff leaking oil around the rear seal. have you heard of this problem?

 

[bcrawford]

Who are fooling TANGRIZZ? I have personally seen you shift at full trottle, going uphill, while spinning. just kidding. Maybe if you weren't such a maniac and know that you're not riding in a sherman tank, then maybe you're front end wouldn't have to be ripped apart this weekend for repair and we could be riding instead !!! And for records sake, everytime you ride by a pond, try to resist plunging off into it. The sherman tank doesn't really agree with that also. But you know we love you anyway !!!

 

[ddcarlton]

redgrizz, are you stalking me ??? how do you know these things ???

just kidding!!!

hey guys - fyi - redgrizz and i regularly ride together in some of the best trails in louisiana... and yes there are plenty of ponds and creeks that call like a siren to the TANGRIZ!!!

When the REDGRIZZ and the TANGRIZ roll out of the truck beds, they start talkin' and the competition starts walkin' !!!

Welcome to the site guys, post some pictures soon.
