Outbehindthebarn Posted 8 hours ago Share Posted 8 hours ago I have a 12 speed with the second gear shift (not on air). It is gated so it can only be used in 1st gear as it should.... The question is, can this be worked around so that shifting through all five gears in the main transmission is possible?

mrsmackpaul Posted 8 hours ago Share Posted 8 hours ago Yes you could easily pull the lid and remove the mechanical interlock But I would wonder why someone would want to do this as deep reduction is so low geared that these other gears are gunna be limited As I remember it the gear sets get thinner as we get up in the gears Maybe the torque through deep reduction is to great for these other gears Mack would of had a good reason for locking deep reduction with first gear only No matter, good luck with it all Paul 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75560-another-12-speed-question/#findComment-576230 Share on other sites More sharing options...
