Assuming by gearbox you mean the transmission.It is computer controlled.Depending on what it is doing it could be a pressure switch problem or internal seal failure

Hello, My 1994 BMW 740i is not shifting into 5th gear on automatic mode, it happens after it being driven for while and is warm, when cold it shifts gear till 5th gear normally, when it gets stuck on 4th...


IMO it's more likely that you have the wrong grade of ATF. It's very important to have the correct grade. The following site shows this:
http://www.nairaland.com/1364064/automatic-gearbox-problems
each car manufacturer has recommended grades of Automatic Transmission Fluid, BMW is no exception. the following website for BMWs may bring you more accurate data:

Apparently CTSC is the supplier for BMWs via the web.
Generally auto gearboxes have drain plugs and filler plugs to enable oil change in routine maintenance. But I would definately go back to the garage where you had the last service and ask politely about the grade of ATF used, before considering an 'oil change'.
Good Luck

Tip

My car does not shift in second gear.


Hi.

The first thing to do is replacing the transmission fluid. Metal debris inside the transmission box gets mixed with fluid and can cause similar problems.

The automatic transmission uses throttle position sensor to determine position and opening of throttle.
IF throttle position sensor is defective, the car may have problems shifting into one or more gears.

The automatic transmission is controlled by an electronic control module, that is energizing a set of solenoids to shift into gears.
The control module is a rectangular box, often located behind the dash and wired to transmission. The solenoids are attached to valve body,inside transmission.

If a solenoid is defective, or if control module is defective, the car may have problems shifting into one or more gears.

Problems concerning transmission control module, TPS and transmission solenoid are usually detectable reading fault codes stored on the car main control module (ECU/ECM).

Transmission problems are often returning a code p0700 after an OBDII scan.

Stored codes can be retrieved using an OBD scan reader.
If the car auto transmission is not shifting into gear, talk to the mechanic about the problem.
Only when the car has a really high mileage, or when there is a factory problem there is need to replace the gearbox.
A damaged gear box at low mileage is rather unusual.

My 2001 Honda Rancher TRX350FM is stuck in gear (4th or 5th) and I can't get it to shift.


The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems ca cause many drive-ability related problem such as rough idle and other symptoms

Transmission wont shift into 3rd gear


this might be a simple problem with your gear linkage, your rubber bushes might be worn out, get them replaced... or your gearbox might have broken its synchronizer which actually shifts the gear in the gear box... i prefer u go see a mechanic

After driving my 99 chevy malibu for at least a half hour, pull into parking spot and then back out, trasmission doesn't shift into gear right away and if I drive away, I have no power...transmission won't...


its the one on the valve control block inside the gearbox and i think you will have to buy a complete re conditioned gearbox because you will find the spares are not sold seperate ,well that is what i get here in spain but stateside??

Car wont roll forward or back even in neutral


I assume it's a manual transmission.
If the car will not roll backward or forward in neutral (with or without the clutch engaged) the transmission is most likely locked in two gears at the same time.
This may happen if gear selectors are excessively worn. If you are able to examine the gear selection levers external to the gearbox, ensure they are in the 'neutral' (no gear selected) position when the gear lever is in Neutral. If not in correct position, you may be able to manually reset the levers to correct neutral position and thereby unlock the gearbox.
In any case, if it's happened once, it will happen again, so get the gearbox and gear selection mechanism checked for wear or breakage.
