ekennedy21 Posted October 9, 2020 Share Posted October 9, 2020 Does anyone know anything about the shifter dampener on superliners. I believe it was available from Mack to stop the shifter from jumping out of gear on bumpy roads. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/64519-superliner-shifter-dampener/ Share on other sites More sharing options...

Bullheaded Posted October 9, 2020 Share Posted October 9, 2020 I used to drive an E9 Superliner with a 12 speed Mack and it literally used to shift itself, LOL It would just fall into the next gear on it's own. But at least it did it at the right time, LOL 1 Quote Link to comment https://www.bigmacktrucks.com/topic/64519-superliner-shifter-dampener/#findComment-462140 Share on other sites More sharing options...
57 bcr Posted October 9, 2020 Share Posted October 9, 2020 You're right. My uncle drove a new Super-Liner in '88-'89 for a construction outfit he was working for. It was an E9-500/12 speed. From the get-go,it would jump out of certain gears. Mack had a recall on them and the fix was the dampener. He said it worked okay,but thought it was kind of goofy. He had to learn to shift that trans differently, but it did work. 2 Quote IF YOU BOUGHT IT, A TRUCK BROUGHT IT..AND WHEN YOU'RE DONE WITH IT, A TRUCK WILL HAUL IT AWAY!!!
