Hello I'm looking to buy and commander with 1,800 miles on it it's fairly cheap the only problem is that the owner claims it only works in reverse. Looking for advice or ways to fix thanks.

If the gearbox is toast get one from MR:RPM
He sells a complete bolt in gearbox for 850.00

Don't know what the rest of it looks like or the guy that's selling it but I would be taking a good look,

Something has to be bent in the linkage. Or the gearbox has a broken part. With only 1800 miles I doubt the gearbox is the problem. Has to be in the linkage.

There is no linkage . There is a cable from shifter to gearbox

Will it not go into gear with the motor shut off or just when it is running. If it will go into gear with the motor shut off then you have a clutch problem, if it will not go into gear with the motor running then it sounds like you have a gear set that may be out of time or a bent shifter fork. Have you rocked it while trying to shift it. And can you get it in neutral?

Thanks for the info so I ended up buying it. What's is doing is making a load grinding noise when you put it in low or high it only moves in reverse.

Drain the gear box oil and flush to see what comes out. Refill. Then get a search on the forum and look up linkage adjustment and just maybe you have a solution, otherwise as said by Troy earlier, new gear box.

FYI. I talked to Mr RPM. A few months ago when I needed a new GB. The gear boxes he has for 850 are gen 1 gear boxes and wont fit Commanders.
As for the grinding I would check the primary clutch. Before writing off the gear box. The one way bearings could be froze up. Or some other issue like dirty sheaves causing the clutch to not fully disengage.

 

[Kasperone]

Ok so I had today I unhooked the shift linkage right where it bolts up at the gear box. And if I align it right it drives in high and low. I had to play with it to align it because sometimes is grinds.

 

[takethetime]

Drain the oil and see what comes out, report back and we can go from there, is there any oil in it?

 

[Kasperone]

That's what I was thinking I'll do so tomorrow thanks y'all been a big help!

MR RPM
Now carry's all three gearboxes for canam

Gen one is for quads

Gen two is commander and standard Mav

Gen two with lower ratio

The 6x6 outlander and Mav XMR .

So if anyone needs one it is a option

That is good to know Troy. Thanks for getting that out there. Back when I had my GB troubles I emailed him and all he had in stock were gen 1s . But I am glad it worked out the way it did for me. I really like the lower ratio Mav GB I got.

To the OP: When I first got my Commander it ground and was hard to get into gear. I serviced the clutch and packed the one way bearings and it was fine after that.........Well till I lost a bearing and blew the gear box Thats is another story
But they lived happily everafter.

Ok so I just drain the gear box oil and about 4oz came oil it was grey no shavings

 

[GOFORIT]

Only 4 oz? I think the gearbox takes bout 450ml when changing oil which is bout 15.2 oz per 2013 shop manual. Looks like you were bout empty and if so no doubt some damage was done if ridden very long. Myabe you caught it in time being no shavings came out.

 

[Kasperone]

I added oil from the dealer and still did the same some times is goes in gear after playing around with it but still makes a grinding noise when driving.

 

[takethetime]

I suspected possible low oil, I think there will be some metal in there laying somewhere. Takes oil up to the filler hole for me. Something is not right and where did the oil go from the start that is gone?

I would get it out and order a new gear box if it were me?

 

[Kasperone]

Pretty hard to change?

 

[takethetime]

Yup it's a job, but there are a couple of threads that could help you, do a search if you feel it's within your reach, may want a friend and a few beer around, it's a six pack each for sure.
