i purchased a brand new massimo tboss 410 and from day 1 it wont operate in reverse.  When i pop in reverse and give it gas it will die out.  when i pop in reverse sometimes in will die right away (before giving any gas) and 1 time out of 100 when i pop in reverse it will operate perfectly fine.   and yes, it operates perfectly dine in normal drive H and L.  any thoughts??   when i called the dealer i got it from they had no idea.

Did you ever find a solution.  Mine has 39 miles on it and dies everytime you put it in Reverse.  Nobody seems to know why!   VERY FRUSTRATING!!!

We are having the same issue with the Boss 550.  The reverse is giving us problems.  Its not dying out, but just not going. Got the reverse beep, (ANNOYING AS HELL) But is not wanting to go in reverse. Sounds like some ringing in there. This thing is brand new. It hardly gets used, and its not like it turns on a dime, so without reverse we are basically without it.   This thing wasnt cheap, and its problem after problem. Forward is fine.   CMON yall.... whats the deal? Is your buggy just junk? Is there a fix? 

Kinda wishing we got something else.

Most likely needs the shift cable adjusted, but also make sure the rear differential fluid is at the correct level.  These "dealers"  know nothing about the machines they are selling for the most part.  If you don't know what the level should be, it should barely touch the end of an allen key when inserted (about 3/4" below hole).

As TapBoss said, most likely the shift cable needs adjusting. If new it was not adjusted right from the getgo. If older the linkage is warn or cable is stretched. 

Either way the manual should give directions on how to adjust the cable. If nothing search YouTube for a couple video. If you can't find one for your model look for a setup that is close.

Unfortunately the manual doesn’t, at least not that I could find

So I also have a Tboss 410 with the same issue. Almost as if it is stalling out. I also notoced the speedometer is not reading the speed correctly. When im idling in nuetral the speedometer shows im moving when im not. When im driving in forward the speed is not accurate. I had previously unhooked the back up beeper and i thought that is what caused the issues so i reattached it. Issue still exsists. Everything works fine driving forward in H and L. other than the speedometer not working accurately. It just really does not like going in reverse. Sometimes all I ha e to do is shift ot in Reverse and it stalls. Any thoughts?

I have recently encountered this problem on my 2022 Massimo 410 t-boss. High and low gear work fine. Dies instantly as soon as it is given any throttle in reverse and speedometer is haywire. For six months I have checked everything from fluid levels, to cable adjustments, to throttle position sensors, to O2 sensors. I have reset the CPU all to no avail, until recently. There is a connection located under the output shaft of the transfer case, that is pretty well hidden, that vibrated loose and became uncoupled. As soon as this was reconnected reverse works flawlessly, speedo is accurate and there is no more surging in high gear. I hope this helps as the dealers and Massimo support are of very little assistance.

      TBoss Enclosure
      By TapBoss
      So I’d been shopping for an enclosure for my ‘21 TBoss pretty much since I bought it. Then they came out with half doors and that’s the only one that I could find. Then the other day I ran across one on Amazon for half the price of anything else I’d seen. The link is below and I’m pretty impressed by how well it fits. There is one Velcro strap on the top of the door that doesn’t line up well with the roll cage, but I’ll work around it.

      2017 TW450 Kohler ECH440 runs out of fuel when running wide open.
      By Sammy
      Runs fine just putting around the yard. Get it out on the road and about a half miles it runs out of gas. Let it idle for a few minutes and it will run for another half mile and do it again. Replaced both fuel pumps and filter. Does anyone know if I can get rid of the factory fuel pump?

      Hisun Sector e1 Battery replacement: any tips?
      By didgeridoo
      Hello, All!  I've decided to replace the traction batteries in my 2018 Sector E1 with a 48V Lithium set. They may be expensive, but I figure the Discovery Dry Cell are, too. I am not looking for the max driving range, as I have never received near the brochured range to begin with, but a good mix of charge/ get work done/ charge is what I am expecting.
      I have settled on the 48V EAGL kit from bigbattery dot com. Each battery pack provides 30Ah. The kit ships with a charger, as well. The packs would be physically connected in parallel (using a busbar) to one another, maintaining the 48V voltage, but together would be able to provide the amp draw the buggy pulls when going up hill or towing a rake (rated 320 max continuous Amps). This is in comparison to the serial connection the eight 6V lead batteries. Each of the EAGL batteries looks to have its own BMS; am I correct in thinking I will have to use their included charger rather than (simply) changing the onboard charger to lithium mode? The chemistry of the pack is LiFe PO4, for what it's worth.  I haven't torn anything apart yet (to diagram), so  I am not sure how the dash will interpret the AMP draw, but the kit I am looking at includes a dash mounted charge indicator.
      If anyone has completed a similar conversion, do you have any tips? Specifically, how did you remove the original batteries, and how did you secure the new ones? I am guessing that almost any change from the stock batteries would involve at least some modifications. Any tips would be appreciated, especially things I may have failed to consider. Thanks!
