My Isuzu trooper 1998, is flashing the on the fly shifting indicator, but the switch for the 4x4 is in the off position... i turn the ingnition key and it lights up and then it turns completely off, but after a while im driving it starts flashing, and the transmition starts to give me issues while trying to accelarate.

Was it lined up right as the trigger point for the sensor is important.Is the fly wheel fitted one position only that the bolt holes line up or will it fit no matter which position it bolts up Line up the flywheel trigger with the sensor after you have put the engine to Top Dead Centre.Put at tdc and see if the trigger and sensor are together.

Follow your oil's gauge, is it working when the "check engine" light is on?

hi guys i would check all the small vacume pipes that conect the sol valves toi the vacume actuators having just replaced the engen in mine i found that these do not have any clips holiding them on tight and can get oil on them and become oversized and leak you can test the diaframes in the actuators by putting a length of pipe on one port and sucking by mouth you can hear the actuator move and then find you can put toung on end of pipe and it will hold a vacume if it does not then chances are the actuator diafram id u/s hope this helps bill

Check fuse link.

Usually elecrical, switch, wire, connection, or mechanical adjustor on shifter linkage. I had the retainoing bolt break on me for no reason.... No biggie just a pain in the Donkey :-)
