Re: Allison Transmission Model 3060 shifting trouble
OK, You have a mechanical engine with an electronic trans. This means there is a cable operated tps switch conected to the throttle linkage. it could be sticking, disconected or just bad. Did you get any codes when this problem occured? I would look at the linkage and see if it might just need lubrication or is disconected first.
Good luck

RE: Allison Transmission Model 3060 shifting trouble
my 93 gulfstream has this tps disconnected. actually looks like the linkage broke or was disconnected along the way. still shifts, but sometimes hard between 2-3, i connected it va rigging up the cable to the throttle linkage and then i found it wouldn't switch into 1st from n (sometimes). disconnected it and it seemed to fix n-1 trouble. now it is disconnected and still having the n-1 trouble and it just beeps and flashes 6. i shut down the engine and every once and awhile it shifts into 1. any ideas?

Re: Allison Transmission Model 3060 shifting trouble
when i bought my my 93 gulfstream cummins/allison md3060, 2 years ago, it had the tps disconnected. actually looks like the linkage broke or was disconnected along the way. still shifts, but sometimes hard between 2-3, i connected it via rigging up the cable to the throttle linkage and then i found it wouldn't switch into 1st from n (sometimes). disconnected it and it seemed to fix n-1 trouble. now it is disconnected and still having the n-1 trouble and it just beeps and flashes 6. i shut down the engine and every once and awhile it shifts into 1. any ideas? also, the idle is at 1100-1200 that is too high? how do i set the tps up? make sure it is working? thank you in advance!

1100 - 1200 engine RPM is too high. With the TPS connected, the MD won't allow a neutral to range shift above 900. I have sent you the TPS info.

I think that this information is the best.
