Why your semi transmission is grinding and not going into gear. Listen for yourself.  

I always thought that a clutch brake that didn’t work well was a clutch brake that had just worn out it’s friction material. Good to know that a clutch adjustment can fix this.

Great explanation. One trick to avoid it is to count to 5 after pressing the clutch pedal, then engage the gear.

The best explanation I've ever seen! Thanks very much!!

Mine makes that sound only when I’m in low gears if I let off the fuel the rpms go to idle and make that grinding noise, also it does that in reverse pain in the ass to backup I thought I needed a whole new transmission, thanks for the info.

Thanks for your meticulous explaination

Fantastic explanation!

Great video!

I’m having the same problem but I installed a new clutch and still does the same thing

I have a freightliner cascadia 2016 and just put in a new (self adjusting clutch) basically what was installed when trk was new. I have had so many issues with this clutch. I have maybe 2500 miles on this new clutch and indicator shows 50% now. I had no issues with my transmission until putting this scrap metal in. So basically can this be fixed or just remove and install something else. Pretty sure freightliner not going to warranty this OEM part.

Did you go thru and show the difference between the clutch adjustment and the clutch brake adjustment. . . . for the regular manual clutch linkage..not the hydraulic?

How do u know exactly when u need to adjust clutch?

Would a non-stock shift stick affect the "ease of getting into gear"? I have an ever so slight grind you described with the slider clutch?. I swapped in an 18spd that's F-designated (RTLO*F*16918B) ... and had to use a junkyard sourced shifter that j-hooked to the shift tower. I always wonder if that may be a reason for the imprecise shift feel. Also, im having to adjust my clutch every 10K miles, and lube the throwout bearing every 3K miles (else i detect a rattle) ... Is this normal?

Hi good afternoon I own a fld120 for 13 years now have a 18 speed eaton clutch and doing something to me never do before after the truck been parked for couple days ( raining here a lot of humidity ) truck start ok but grinding when trying to put on gear looks like clutch getting stick to the flywheel pressing the pedal clutch So in order to release the clutch from flywheel my mechanic told me to put the brake put the truck on the lowest gear ( truck off ) press the pedal clutch and start the truck and that works the clutch starts working correctly My question it’s that normal ? Something getting bad on the clutch ? Any suggestions ? I would appreciate it Thanks

Mine will go into 1st gear but grind real bad going into every other gear. Do you think the clutch brake is not stopping the transmission? It's pushing the throwout bearing into the pressure plate.

I have a 13 speed Eaton and when I put it on nine gear it sometimes kicks out. I guess I need to rebuilt it?? How much will it run me to rebuilt my transmission?

So is that the same noise when u go from low to high with the splitter and it make a noise go to 5th in a 8 speed double LL

Mine probably got no teeth

what if my shifter is vibrating as well, at idle, neutral, clutch out it vibrates, clutch in hard to get into first and reverse, goes into 2nd and 3rd but with grinding that slows to a stop and allows shifter to get into the gate after a second or two of light pressure at the gate. eaton rtx 10 speed.
