I have the Eaton 18 speed auto , Shifted terrible from new , Had the Eaton rep reprogram it , He loaded the “west coast program” as he calls it ( I’m in BC ) , Now apart from the odd harsh shift , I’ve been very pleased with it , Wouldn’t dream off going back to a standard . I have a low range which can be used for more aggressive downshifting and the Jake works great on the ■■■■■■■ 525 , Mine shifts down seamlessly , or I can just flick the lever manually , never miss a gear lol
Yep, like I said, the 2013 one works fine and that new 12sp Detroit box is very good, just this new 18sp Ultrashift is ■■■■, we tried it in Performace, then Economy, then ended up back in performance again, now I’m using Manual all the time going up the box ‘cause it’s holding the gears too long.
And speaking to the foreman in W/Star this week, he said that they have also dropped back the power of the Jake’s performance so they are not as powerful as in previous models.
