fullfuel01 Posted June 27, 2013 Share Posted June 27, 2013 While changing the fluid in my 18 speeds mack (t2180), some part of the main input shaft bearing dropped in the pan.. i don't like the 18 from Mack, I want to keep the superliner all Mack. If I put a 12 speeds, I'll loose overdrive (from .71 to .78)Question: somebody know someone that can make the 12 speeds more overdrive by changing gears or whatever? or whre can I get my 18 fix forever? I'm looking for the guy that can give me any parts number in a 12 speeds with all the update that mack made while drinking his coffe during the morning break!!

oilburner Posted July 8, 2013 Share Posted July 8, 2013 You might go with a Mack nine speed. I maybe wrong but they are a .60 overdrive and they have a good low hole. If you have enough motor to pull out the big jumps in the ratio of the trans Quote Link to comment https://www.bigmacktrucks.com/topic/31735-mack-12-speeds-overdrive/#findComment-193175 Share on other sites More sharing options...
RFCDrum Posted July 8, 2013 Share Posted July 8, 2013 T318. The 2180 had a very slow splitter. The 318 shifts very good. When we swapped out the 2110B out of the RD I drove we talked about a 12 behind the 460 but for some reason you couldn't do it. Went with the 318 instead. Got the only rebuilt one in North America at the time. Couldn't find them.
