farmer52 Posted 16 hours ago Share Posted 16 hours ago I am looking at a CH613 that has a Meritor Rockwell 10spd transmission. I am unfamiliar with MR transmissions. How do they compare to Eaton - shifting, durability, parts, repair, etc.? Also the owner states the shift lever "wobbles" when driving. Is there a spring that needs replaced? Or are internal parts worn? The truck has 600K+ miles. I don't know anything about the history. Thanks!

Joey Mack Posted 15 hours ago Share Posted 15 hours ago I found that Eatons shift smoother, but i only drove a few, and owned 1 meritor 10 speed. But I remember doing 'in chassis' synchro replacements and it was just like doing an Eaton. As far as the sloppy shifter, look to see if its a 2 peice shifter like an eaton. Then you can replace the bushing at the joint like an eaton. I bet ive changed 50 of them..

Geoff Weeks Posted 15 hours ago Share Posted 15 hours ago There are likely 2000 Eaton's for every 1 Meritor. For parts alone, your better off with what everybody else has. Neighbor had one, I don't know what the problem was but he complained a lot about it. Both are a box of gears, and put together much the same way. Look at the stick right above where it goes into the transmission for an isolator bushing. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76236-eaton-versus-meritor-rockwell-transmissions/#findComment-587180 Share on other sites More sharing options...
Geoff Weeks Posted 15 hours ago Share Posted 15 hours ago Page 116 shows the isolator, just like Eaton. Meritor parts 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76236-eaton-versus-meritor-rockwell-transmissions/#findComment-587182 Share on other sites More sharing options...

farmer52 Posted 14 hours ago Author Share Posted 14 hours ago Thanks everyone for the comments and info. There is a rebuild kit (KIT5237) on fleabay for $20. I will pass this on to the seller. And I will likely pass on this CH. Prefer single axle.

BottleHauler84 Posted 13 hours ago Share Posted 13 hours ago I owned a 9400 International one time with a meritor 10 speed. I hated that transmission. When it had the first sign of syncro problems, I went back with an Eaton. I like it alot better. Just my personal experience tho. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76236-eaton-versus-meritor-rockwell-transmissions/#findComment-587199 Share on other sites More sharing options...
Joey Mack Posted 13 hours ago Share Posted 13 hours ago Funny how that is.. similar structure, not as good as eaton.. i had a hard time shifting my Meritor, after driving a ton of trucks at the shop with Eaton, and Mack transmissions. I did learn it, but didnt like it. However, i did like the cruise buttons on the shift knob, kinda made slow speed changes a breeze.. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/76236-eaton-versus-meritor-rockwell-transmissions/#findComment-587201 Share on other sites More sharing options...

I cant understand why the meritor was not nearly as smooth as the eaton. Never did tear it open to dissect it to learn, but I wish i would have. Im bad about having to see the inside of things like that. Been tearing things up ever since childhood lol 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76236-eaton-versus-meritor-rockwell-transmissions/#findComment-587203 Share on other sites More sharing options...

I looked at it like this: Eaton made close ratio main box with repeatable shift pattern, wide ratio range box. Spicer made wide ratio main box with close ratio splitters, with a non repeat shift pattern What did Meritor bring to the table that was better or different? 2 Quote Link to comment https://www.bigmacktrucks.com/topic/76236-eaton-versus-meritor-rockwell-transmissions/#findComment-587211 Share on other sites More sharing options...

I agree the rockwell was a knock off trans that didn't make the grade piece of crap copy ! don't think it was Chinese but it might as wall have been! rock well clutches were ok but real grabby !
