Chances are, particularly if this is an automatic transmission, you are low on tranny fluid. To check this, the engine needs to be at normal operating temperature and idling. Checking tranny fluid when the engine is cold and not idling will give a false reading, indicating that it is full ...
As long as the engine is at full operating temperature and you do not rev it beyond the red line, you more than likely will do no damage, but it is still not a good idea. Revving a cold engine will do damage for sure. Revving the engine can cause a sudden drop in oil pressure, cause the engine to over heat and it doesn't help the main crankshaft bearings any good as they and meant to be revved under a load(in gear).
transmission, I'm afraid--may be able to coax t a bit by gently revving engine, kryword gently. :-)
because in park or neutral the engine is free revving and when put in gear the engine is now turning internal transmission componets which puts a load on the engine
When you are driving on the highway / freeway your engine will be revving higher , your maximum speed will be reduced , with your engine revving higher it will most likely be noisier and I'm assuming your gas mileage would be poorer , just like not using your overdrive
When you attempt to take off and raise the clutch pedal, the car is noticably slower to move off. To the point where you're foot may be all the way off the clutch yet the engine is still revving higher than normal and the car is not moving forward at the normal rate for your first gear.
po734 means incorrect gear ratio. It probably is telling you that the engine is not in the right gear range to produce the power you need or that it is in too low a gear and is in danger of over revving. Normally you won't see this on a vehicle with an automatic trans unless there is a transmission problem. I have same code and i had to put in tranny cause it did go out..what a job. engine on mine had to come out to get to it cause i dont have a shop or a lift.
Try locating and testing or changing the TPS (Throttle Position Sensor) Or if it's not in gear it could be the rev limiter keepin you from over revving & blowing your engine.
Usually, the engine flywheel. A solenoid in the starter moves the starter pinion shaft forward (or backward depending on how it is mounted to the engine) to engage the outside edge of the flywheel (which has teeth to match the pinion gear).
May be you didn't change your gear. Hahaha :))
the lowest forward gear
Use what the manufacture suggests. Consult the owners manual for the correct oil for the engine.
A Ford F250 diesel will not move forward if the transmission is not in gear or it has suffered a catastrophic failure. The transmission is responsible for moving the engine's power to the wheels.
