2000 Isuzu Trooper 6 cyl Four Wheel Drive Automatic 170000 miles
Been a mechanic for 12 yrs just not too familiar with these troopers. Bought this vehicle this way-start driving and when it gets to about 3500 rpms it tries to shift but just neutrals out and revs up. Already cleaned PRNDL switch and serviced tranny (which I think it did have the original filter in it). Ive seen this issue alot online but havnt seen any answers.
