Gmerrill0516 Posted January 9, 2013 Share Posted January 9, 2013 We have an 8LL in the roll off with an E7-427. The 8LL has issues where 3rd/7th pops out of gear unless you brace yourself against the lever. I'm guessing it is a detent failure as it is otherwise quiet and shifts ok. I found a guy with a good used "10 speed maxitorque" transmission for sale at a good price. One thought was to swap in the 10 speed and save the rebuild expense. The other idea was to skip 3rd and 7th and drive it. The truck is kind of critical to the operation so having it quit would be bad.Would the two transmissions be interchangeable without shortening the drive shaft and bolt right in or would modifications be necessary? Any idea how big a deal it is to dig into the 8LL?Again, thanks for any ideas, knowledge and suggestions.Greg Quote Link to comment https://www.bigmacktrucks.com/topic/29265-will-a-10-spd-maxitorque-trans-fit-where-an-8ll-was-or/ Share on other sites More sharing options...

2stacksuperdog Posted January 9, 2013 Share Posted January 9, 2013 We have a 2001 RD with a E7-350 with an 8LL and it does the same thing and i still think the Avon Mountain crash was caused by the same problem because we know a bunch of people with the same specs as our RD and their 8LL have the same problem. Also the truck was up at Gabrielli Mack 3 times and they kept saying it was poppet springs and balls until the warranty ran out and then changed forks, complete bearing kit, and sliding clutches and expected us to pay for it and it still jumped out on the way home from there Quote Matt Link to comment https://www.bigmacktrucks.com/topic/29265-will-a-10-spd-maxitorque-trans-fit-where-an-8ll-was-or/#findComment-156240 Share on other sites More sharing options...
