2018 Cub Cadet Challenger 750 shifting problems

Recommended Posts

I generally use my challenger for light duty misc. use, and for plowing. The one thing I dislike about this machine is the difficulty in shifting. I've had it the shop and they adjusted the shifting lever, but I still have issues. Some times it shifts ok, but the problem is it is hard to get it to move the lever from high to reverse or low to high or from any gear to the other. Seems I always have to accelerate a little to get it to engage to what gear I need it to go to. This is definitely not normal.

You probably have too much grease in the primary clutch housing that has the weights. I had the same issue with mine. Over a cup of grease in there! The roller weights in there need to move and won’t if cold due to a cup of 90 weight gear oil. Manual calls for slightly greased with 90 wt oil. I live where it is very cold in the winter. I used moly dry spray instead of grease.

I Have a 2017 Challenger 550.  it is a piece of S*** it has 324 miles and 112 hours on it and is currently in the shop getting its 4th new clutch that is an average of about 28 hours per clutch.  this machine is not abused at all it is lightly used around the yard and was intended to plow my driveway but can't even use it for that since the clutch system does not allow you to back up any inclines without burning out the clutch and the shifting of this machine is pathetic,  I have been going back and forth with level 3 tech support and they seem to put the blame on me for user error everytime.  I was told today they i should never put the machine in a position where i would have to backup from a stop with any incline (LOL) you pay $15000 for this thing and you have to drive it on flat surfaces.  *********Buyers beware these things are junk**************

 I have I have the same your Cub Cadet 2018 Challenger 750 and I have new shift to put in it and all the new shifter is giving me problems and I found out that if you brake lightly you can go from low high and neutral and if you can't get a past neutral into reverse or Park, brake a little harder and it should go all the way up reverse and Park. Hopefully that helps you out. I took my old one apart and there's only two little pieces in there besides the shifter and a spring into little levers at hit notches.

I have a 2018 Challenger 750. I would occasionally have this same problem shifting but could always resolve within a half dozen attempts.

Today was different. After a short run, I was in Reverse, backing it towards the garage. I then went to put it in High to move forward and adjust my angle. While I was able to move it past Neutral and into Drive, the display still showed R. I tried changing gears again thinking it didn’t click into Drive right but when I moved to Low, High admin, and then Neutral, the display still showed a R. Next I put it into park and the display finally changed to P. Now I can’t get it out of Park. No matter what gear I move it to, the display shows P. It will not move no matter what gear I try. 

Anyone seen this before or have suggestions? Thanks!

      I have a 2018 Massimo Buck 400 with 278 miles. 
      Having issues with my brakes. Took the buggy hunting and when I let my foot off the gas pedal it pulls without pressing on the brake. I looked and the pads on all 4 wheels are all toast. The E-Brake hasn’t been on since I have had it. I am guessing it may be a master cylinder issue because all 4 pads are gone. They all seem to have worn evenly that’s why I think the master cylinder. Just got the machine used from a older couple and they said it sat for some time in there pole barn. Possibly the brake lines? Calipers? I took one brake apart and when I depressed the caliper it didn’t stay. Any help is muck appreciated.

      I appreciate any advice anyone can give.
      I am working on a Challenger 750 that the drive belt broke on.
      Removed the side cover and spun the primary drive sheaves. Something was clunking.
      Took it off and pulled the outer cover and all of the rollers were out of their spot and clunking when rotating.
      I noticed these rollers are not round. They have 2 different flat spots on them. Are they supposed to be round?
      If not, How do they go back in? Flat side down, up, I don't know.
      I apologize for not explaining this properly. I was just hoping someone has seen this before.

      My "R" light on the dash will not go out when I take the UTV out of reverse and put it into any other gear. Is this just the light switch issue or will this effect engine performance in the other gears?

      We see a lot of the UT400 with shift problems, not going into gear, popping out of gear, grinding etc. There  is a bulletin Im sure everyone has saw about adjusting shift cable.  That dont always fix it.  I went round n round with coleman  on couple units. We are a Coleman warranty repair center"AFS Small Engine Repair "   I told them shift lever does not have enough travel .  No amount of cable adjustment  will increase travel . I  extended lever with piece on flat  iron by 3/4 of inch .  This gave shifter enough travel to properly engage into gear completely .  Last couple units to come in for this Coleman sent me a modified shift lever, with longer travel . Problem solved! Also , heads up if you get any new unit ,,,go over and check it out,  grease  all zerks, check air filter for being in backwards, check wiring harnesses for rubbing on rotating parts,  brake hose  routing , make sure not touching exhaust .  These are just  few of the more common failures I see .
