look at the front of the engine on the bottom pulley known as crank shaft at a 10:00 position and another one at bottom of the bellhousing where the transmission meets the engine slightly to the passenger side
in the distributor in the rear of the engine. sometimes known as a hall sensor
I have just removed my crank sensor on my 1991 h reg 2.0l 740(b200 engine)it is accessed from the near side ,there is a connector on the bulkhead about a third of the way in ,disconnect this and follow the wire down to the sensor which is in the top of the bellhousing below the distributor(just up from the starter motor)it is held in by a 10mm bolt untighten this and then move the sensor from side to side to free it,remove sensor and replace with new if faulty.refit in reverse order.shouldn't take more than 15 minutes but is a bit confined.
Right above the oil pan in the center of the block.

Did you ever get an answers to this question? I have a 1990 740 GL with the same problem?ThanksEngine Coolant Temp. sensor ECT (#1346030), sensor for the ECU, not the sensor for the temp gage, I recommend BOSCHLook under the intake close cylinder #3
I am not familiar with your particular make and model of vehicle, but that's not critical as most vehicles today use a crank sensor, or a similar device. Because of my lack of familiarity, this answer will be generic in nature, until an expert on your vehicle can improve this answer. In order for the engine management computer to function, it HAS to know the revolutions per minute at which the engine is running, and it has to know which piston [particualrly #1] is in what position [i.e., intake, compression, power, or exhaust stroke]. Most crankshaft position sensors are combination optical and electrical/electronic devices, meaning that the device senses the passing of a visible mark on the crankshaft pulley, and electrically sends that info to the computer. There is another type of sensor that instead of optically sensing, records the passing of small magnet. These devices usually use a magnetically sensitive transistor [I think it's called a "Hall effect" transistor. Regardless of the details, a "crank sensor" senses the rate of rotation of the crankshaft [thus the RPM], AND senses the position of the pistons. It electrically sends that info to the engine management computer so it can determine many factors of engine running status, and make necessary adjustments [amount of fuel, fuel mixture, ignition timing, and many more]. Until an expert can correct/improve this answer, I hope I will give you a basic understanding.
change the overdrive sensor should be on the left side of the gear box.
