massimo buck 400 grinding noise in high gear, pops out of high gear

[Stubbsmobile]

Hey yall,

Helping a friend out. he purchased a 2020 massimo buck 400 utv. has about 100 hours on it. after starting the engine, shifter in low, it does fine. when shifted to high gear, most of the time it acts like its not in gear completely, and it pops out and grinds bad. when you can get it in high gear, it acts like something is binding and it wont hardley roll before it jumps out of gear and makes that grinding noise. almost like trying to dr4ive a standard transmission car and start off in 3rd or 4th gear.

I have been on this site for several hours now, and totally understand the overall feeling about massimo utv. I can only imagine trying to find transmission parts when other members cant even find a fuel filter, lol.

A new transmission is (part#47516) $1159.99 plus tax and freight.

anyone have any other ideas or suggestions on what is causing the noise in high gear and not wanting to move?

Thanks ,

Chris

Sounds like there is an adjustment somewhere to be made. Either on the cables or linkage on the transmission maybe? May even be a bolt or something on the tranny you adjust in or out?

Have you gone online to download the manuals? I would download everything they had just for reference if anything. If there is an adjustment it should be in there somewhere. If not then maybe contact a garage that works on sxs's and hopefully they can point you in the right direction.

thanks for your response!

I downloadedwhat i assume is the manual that is posted here i believe, didnt seem like much help. its wierd, its like low and reverse run out fine, its just hard to feel the high gear engage, and when you try and take off in high, just about the time it starts to move, is when it pops out of gear. ill recheck it again, ive got the belt cover off and the rear end lifted to see if it will without a load on it.

Thanks!

 The only thing I figured out, "Dynamic System" means engine/transmission and "Final Drive" is axle/wheel hubs. Be aware the oil weight suggestion is in Cent and not Fahrenheit in that manual.

 I looked at the manual here also and can't quite figure it out either. It does say at chapter 3.12 (Pages 60/62)  in the "what if" section and refers to the "Vehicle section" for adjustments. Which I couldn't find. lol

Maybe trace the cable or wire down to the transmission and check out that area?

 I believe Tractor Supply is one of the dealers and maybe has a better copy or more manuals thru them? I would imagine they have a local shop to do their warranty work and you might see if you can find out who it is and give them a call?

 Good luck on your mission//////

Hey.

Thanksfor responding, and you know i didnt want to sound like an ass by commenting on that manual, but ill agree, its pretty useless, lol.

i took the belt cover off but need to check the idle and i had already questioned the owner about the oil, and that may play part also. im going to change the oil, and take the shift cables off, maybe pull that shifting mnechanism off and have a look. 

what sucks is that only SONME parts are available, and say if the main shaft is bad, and you cant get it, its replace the transmission.

Ill keep you posted and thank you again!
