    If the computer (PCM) was not working the check engine light would be on and the car would not run, this sounds like a planetary gear vibration or pump vibration and is most likely mechanical and not electronic, have you pulled the trans pan to check for excess debris in the pan?

Disconnecting the battery is what resets the computer on this model year. Try disconnecting the Pos battery cable for 15 minutes. If the problem presists after connecting the battery up again, you have a problem with Idle Air Control, EGR Valve, etc.

Check for a worn universal joint on the drive shaft going to the rear wheels.

Check your transmission fluid level. (Low level can cause vibration on acceleration.)

Check to see if your transmission filter needs changing.

Does it only vibrate under heavy acceleration?

MY Hyundai Veracruz engine (3.8L) idle too low (600 Rpm) in cold weather (less than 40F), when engine is warm and transmission on drive and vehicule stop. This cause a undesirable vibration. When outside...

It may be no engine thermostat which keeps the engine temperature at a constant 180F usually. Or you have some bad connections to a temperature sensor that sends temperature information to the Ecu (brain) and controls fuel. Corrosion causes
bad connections If you have an auto parts store scan your error codes that will be a better diagnostic. It is possible a problem with transmission fluid level or quality of fluid.

Bad vibration in reverse

This could be anywhere in the drive-line. Process of elimination would be the best approach. From your symptoms it sounds like the bad vibration is noticed at low speeds. There are many moving parts within this system. Were there and recent repairs performed? New tires could cause a vibration, if the tread is aggressive. Damaged wheel-bearings, defective components inside the rear differential (suspect low fluid level, damaged ring and pinion or bearings), defective U-joints, or internal transmission failure. You didn't mention if the truck was 2wd or 4wd. If the vehicle is a 4X4 then you will need to inspect the transfer case, the U-joints in the output shaft, and the front wheel bearings. I'm not sure how far you want to go with the diagnostics. Please write back if you have other questions or to give an update to how the repair is going, good luck.

2007 Hyundai Santa Fe 2.2 Diesel, transmission went into neutral while driving.

Check transmission fluid level if low on fluid it will suck air and transmission forward clutch can not apply. If fluid is full and clean looking RED in color shift control solenoids are the problem and internal. BROWN and BLACK fluid indicates the forward clutch was slipping and now has no holding power for movement. this case the transmission needs reconditioning.

I believe it is a power steering pump. My car does the same thing and the power steering fluid was low. We completely filled the power steering and a week later it was low again.

1997 magna transmission vibration at 80k

First check your transmission fluid level before doing any test. Make certain this is not a speed vibration from the wheels by shifting the lever into 2 instead of D and reaching the speed you are having vibration at (as long as it is safe and you are not over reving the engine). While at that speed shift into D and let the transmission go into it's normal gear ranges and take note if the vibration occurs. I've seen (felt) this type of vibration many times on vehicles where the fluid is low. Adding fluid to the proper level solved this issue on some but on others there was existing transmission wear that this would not help. This doesn't mean the entire transmission is bad as the valve body inside the transmission fluid pan can sometimes cause this. Swapping out the valve body can be pricey but not as pricey as a new transmission and sometimes cheaper then having a used transmission installed.

I have an orange light with a oil can picture but its not the oil light an the coolant and windscreen wash is at the right level thanks

transmission fluid level is low, if it isn't the oil light, but as a precaution, check the oil level anyway just to be sure. If it is an automatic transmission, I do believe it would be the transmission fluid being low. check your fluid levels.

Drive or reverse takes a moment before it engages sometimes i have to increas rpms

This is a simptom of low transmission fluid - check your transmission fluid level by pulling the dip stick out of the transmission (found in engine compartment) - must have the enigne running - e brake on and in neutral - if level is low add mopar transmission fluid - if level is good there is an internal problem in the transmission
