I´ve got 1995 6.5 turbo diesel GMC Suburban. 230000 driven. I´ve owned this wehicle for two months soon.

Stange troubles appeared after driving few hundred miles. (Means I´ve driven few hundred miles with that now) Tranny or engine does not work as it should. mad.gif When driving ~50mph the tranny can´t decide which gear to use.. lock on and off.. And wehicle moves really sticky, does not matter if it´s cold or warm. When starting to move sometimes truck does not react to accelerator pedal and sometimes it works fine. Is this kinda solenoid or sensor problem or what? There is only one trouble code, 36 (injection pulse width error(time long)). Does it relate to this problem? PMD/FSD is new and remote mounted. Fuel, oil and air filters are new and motor oil and trans fluid of course. Oil level is allright.

I had 1994 6.5 ext.cab before and it moved much slicky with no this kinda problems ever.

Any ideas?? :)
