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.hardcorecanuck - 8/7/2009 2:05 AM
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!
