F30 Transmisstion Gear First and 2nd Gear Bad

Top seven BMW Manual Issues

The most common issues that cause a BMW transmission to malfunction include:

Depression manual fluid level - The vehicle volition bulldoze OK at first and so go into limp style. Fluid leaking effectually the oil pan gasket or wire harness plug to the transmission is common on loftier mileage BMW vehicles.
Defective mechatronic unit - A prevalent issue is a faulty valve body also known as mechatronic units in BMW terms. The vehicle will no longer change gears and will throw warning messages on the dashbaord.
Battery as well weak- low voltage is a common reason a BMW gets stuck in gear.
Faulty alternator regulator - Transmission issues are sometimes caused due to a bad voltage regulator mounted on the alternator.
Faulty MAF sensor - You may experience transmission issues such as erratic shifting between gear changes.

Equally you can come across in this list, BMW transmission problems such as no shifting or erratic shitting are not always caused past the failure of a transmission component.

To diagnose a BMW transmission, you will need to use a BMW browse tool and read the codes from the transmission command unit.

When the engine command unit (ECU) detects a trouble that can lead to manual damage, the vehicle forces the transmission to go into limp mode to minimize further harm to the manual.

BMW Transmission Fault

In prophylactic dwelling house or fail-safe mode, otherwise known as limp mode, the transmission stays in second gear and no longer shifts.

Common BMW Manual Warnings & Symptoms

Common BMW manual error messages and malfunctions:

Transmission Failsafe Prog. Warning signs
Manual stuck in gear.
BMW Transmission slipping
Manual shifts hard, non smoothly.
Transmission malfunction drive moderately message
The engine revs up, but the manual refuses to shift.
The lag betwixt gears such as 1st to 2nd, 2nd to 3rd
Gear ratio fault codes
Fluid leak on the ground
Shifting gears is delayed
Crude shifting between gears primarily 2nd to 3rd
Transmission service due now message on dashboard
Burning smell from under the motorcar

If your BMW transmission is stuck in limp mode or won't shift, first check that the bombardment is fully charged.

Next, start with the near simple and basic steps.

Restart Engine

If your BMW displays a transmission error message or is stuck in gear, the first thing you should do is find a safe location, turn off the engine and restart it.

Restarting engine can sometime fix your transmission problem

Await at to the lowest degree one infinitesimal before yous start the car. This can reset the engine command unit, and the manual message may turn off. It doesn't always work, just information technology is worth a try.

If your BMW is back to shifting normal, don't presume there is nothing to worry about. At that place is a high chance you will experience the aforementioned manual problem once more.

To detect out what is causing transmission trouble, nosotros recommend post-obit this guide on reading BMW fault codes. In this case, you want to read the codes from the transmission control module.

Reset BMW Manual Adaptive Settings

reset bmw transmission

If you lot accept noticed that your BMW has erratic shifts or does not answer accordingly to the gas pedal, the problem may be wrong shift points.

Attempt resetting the adaptive transmission settings. This procedure is straightforward, requires no tools, and but requires a couple of minutes.

Procedure

It does non harm the transmission; information technology simply resets gear shift points to factory settings.

Turn on the ignition. If BMW has the Beginning/Stop button, press the Beginning button but Non press the brake pedal.
All the dash lights volition plough on. THE ENGINE SHOULD BE OFF.
Now, press the gas pedal to the flooring and keep it pressed. (Ensure the kick-downwards switch is pressed )
Go on the gas pedal pressed for 30 seconds. (During this procedure, the engine should be off, ignition even so on.)
Release the gas pedal.
Kickoff engine and bulldoze.

This will reset your transmission, shifting to original factory settings.

In other words, the BMW will erase the adaptive transmission shift points. BMW volition monitor your driving patterns for the subsequent few driving cycles; do not drive aggressively.

This process does not clear whatever codes or reset the check engine lite, just it can prepare your manual problem in some cases.

What Causes a BMW Transmission Malfunction

1. Transmission Mechatronic Sleeve

BMW Mechatronic Sleeve

BMW mechatronic sleeve is located on the passenger's side of the transmission near the automatic transmission.

This is where the wire harness from the Transmission Control Unit (TCU) connects the transmission.

Unplug the wire harness and inspect for oil contamination. If there is whatever oil, the advice between the transmission control unit and the mechatronic valve torso is interrupted.

To replace or cheque for leaks, you will need to get your BMW up on-ramps. Remove the splash shield from nether the transmission and unplug the wire harness.

2. Mechatronic Span Seal adapter

BMW Mechatronic bridge seal adapter

A BMW may display a Manual Fault warning bulletin on the iDrive screen due to a croaky adapter BMW Mechatronic adapter (Office #: 0501 215 783 01), known as trans seal grommet, for the mechatronic valve trunk.

Under normal atmospheric condition, the grommet allows the fluid to flow from the transmission to the mechatronic valve body without any fluid loss.

This allows transmission fluid to get in to the mechatronic without whatsoever pressure loss, allowing normal gear shifting.

The grommet or the plastic adapter tin scissure over time, which allows the fluid to leak at this port. When this happens, the fluid pressure at the mechatronic valve body is reduced.

Because the fluid pressure is reduced, the valve trunk's solenoids cannot open and close properly, triggering the manual fault or erratic shifting.

This role is easy to supersede and comes in plastic or aluminum.

The OEM part sold at BMW is ordinarily plastic, but upgraded aluminum adapters can be purchased online and last longer than the plastic version.

This problem is common on these BMW transmissions: 6HP26, 6HP28, and 6HP32. Aluminum Part Number SFC-MA-001 is available.

Some other indicator that this office is broken is that you lot volition typically get the Transmission Fault popup to move the shifter from drive to reverse.

Most affected by this problem:

2001 2008 BMW E65/E66 7 Serial
2004 2006 BMW E53 X5 V8
2003 2010 BMW E60 5 Serial
2005 2011 BMW E90 3 Series
2003 2010 BMW E63/E64 6 Series
2007 2013 BMW E70 X5 Except 4.0d
2008 2012 BMW F01/02 7 Series (except 760i/Li and Hybrid 7)

3. Mechatronic - Valve Torso

BMW Mechatronic

If you read the codes, y'all may get fault codes related to the valve trunk, likewise known every bit the BMW mechatronic.

BMW ZF mechatronics is notorious for 2nd to 1st gear downshifts or shift flares during the upshift. These harsh upshifts and downshifts are oftentimes due to a TTC clutch failure, overheating, damaged solenoid, worn selenoid springs, and other problems with the mechatronic unit.

If y'all checked everything above only are still having problems with your BMW transmission, the cause most likely is the mechatronic unit. If y'all want to relieve money, you can consider replacing only the solenoids in the mechatronics unit/valve body.

If you decide to replace the solenoids yourself, remember to alter the foam strip between the solenoid terminals and connectors.

If yous want a unit that has already been remanufactured and tested, y'all can buy a remanufactured BMW Mechatronic unit online. If you take some basic DIY skills, you can replace the mechatronic unit.

Remember that the unit of measurement may need to be codded to match your VIN. Before you lot purchase a replacement mechatronic unit, check with the seller or BMW dealer if programming or coding is required for your model.

As seen in the following video, it is possible to supercede BMW mechatronic yourself.

If you would instead let a mechanic practice the work, this repair tin can price anywhere from $1500 to $3500.

If you make up one's mind to take the dealer replace the mechatronic on your BMW, it volition usually cost anywhere between $2100 and $3500.

It is recommended to reset the transmission module after the Mechatronic replacement. Drive the vehicle around for about 15-20 minutes, making certain manual cycles through the gears several times to recalibrate the shift points.

4. EGS Manual Calculator Software

BMW often comes up with software updates for the automatic transmission. These updates change the shift points, which improves the shifting.

It has been reported to fix intermittent shifting problems or Safety Style issues in some cases.

You volition need to call your BMW dealer and ask them if a software update for your particular automobile'south transmission.

5. Transmission Stuck FailSafe Mode due to Weak Battery

We have seen cases where the BMW transmission volition become stuck in second or tertiary gear and will non come out of failsafe mode even if you restart the car.

In one example, this problem was caused by a expressionless bombardment that stored hard codes.

Fifty-fifty though the BMW battery was replaced, the motorcar remained in Failsafe mode. Typically a BMW volition go into failsafe style if the voltage is nether 11 volt.

If a fault code is stored in the EGS module, you will demand a BMW Specific Scanner to clear the mistake codes from the EGS module. First, acquit diagnostic procedure to repair the trouble and then y'all will be able to remove the codes.

Low bombardment voltage can as well crusade the transmission to not get into Bulldoze or Reverse.

6. Showtime Gear Bug

Often the transmission issue may exist due to a problem with the first gear only. To verify that the problem is with the showtime gear, set your BMW transmission in Winter style, which forces the transmission to beginning in the second gear.

If your BMW shifts normally when in winter fashion, that means there is an issue with the first gear. Continue the transmission in wintertime mode until yous get your BMW transmission repaired.

vii. Stuck In Park

If your BMW is stuck in the park and the shifter won't come up out, the problem could also be the brake calorie-free switch or park solenoid.

eight. Transmission Shudders

BMW equipped with a twin-turbo may feel shuddering symptoms, especially during a long trip. To verify that this is the issue, it is recommended that you finish your car and let it cool down.

If transmission shuddering symptoms get away when the engine cools down, the problem may be caused by the twin turbos. A check engine lite may likewise come on. Symptoms often happened between fifty-70 mph.

9. Torque Converter

Another reason why you lot may experience transmission shudder is due to problems with the torque converter. This is ofttimes because the torque converter locks upwardly, is wearing out, and non locking the torque converters.

BMW transmission shudder may likewise be caused due to spark plug or fuel injector problems. If the cheque engine light is on, make sure to scan the ECU codes and then that y'all can get a meliorate idea of why the manual shuddering is happening.

How to Read BMW Transmission Fault Codes

The next step is to read the fault codes from the transmission module, also known equally the electronic gearbox (EGS).

You will need a BMW scanner to retrieve fault codes from BMW modules. With a BMW scanner, you lot can perform a total organization scan.

Don't utilise a generic OBD-II scanner. If you utilize a generic OBD2 scanner, you will get generic fault codes such as P0720 or P0732, which don't provide enough details on the cause of the problem.

Sometimes, you lot may find DSC or ABS fault lawmaking throwing the transmission in limp style. It is possible that a fault code can put your BMW automatic transmission in Neglect-Safe way fifty-fifty if in that location is nothing incorrect with the transmission.

This procedure will too piece of work on BMWs that have a manual transmission.

Check Transmission Fluid Level

Check BMW Fluid Level

If a bulldoze moderately error bulletin pops up on your BMW, 1 of the start steps is to cheque the trans. fluid level.

If the transmission level is low, fifty-fifty slightly, your BMW transmission tin can go in limp manner to protect the transmission.

Drive your BMW for fifteen minutes to warm up the automatic manual oil. Brand sure to allow the transmission to shift through all the gears. Transition fluid temperature should attain around 100 degrees F. during this driving cycle.
Park the BMW on a level surface or lift it on a lift.
Let the machine in park and at idle.
Raise the vehicle.
Remove the fill plug from the manual. In some models, the drain plug can check the level. You will demand to find out which transmission y'all have.
A minimal amount of fluid should drain from the oil pan if the level is full.
If the level is low, there will be no oil coming out. Exercise not overfill the transmission above the recommended level, every bit this can also crusade shifting problems.

Typical signs that the transmission fluid level is low is that your BMW displays the Transmission Failsafe Prog. Warning under hard acceleration or when accelerating as you lot make a plow.

This happens because more transmission fluid is required during dispatch, or the fluids go pushed to one side of the trans oil pan when making a plow. As the level is depression, there is no transmission fluid for the oil pump, which causes the manual issues such every bit going in FailSafe or Limp way.

How to Alter BMW Automatic Transmission Fluid

A dirty transmission filter or fluid can cause shifting issues, peculiarly in high mileage vehicles.

If you are experiencing shifting issues, consider changing the automatic transmission fluid and filter. It is essential to indicate out that there are many discussions and ofttimes disagreements near whether you should change the automatic fluid, especially on a sealed transmission for life.

In our experience, fresh fluid and a new transmission filter will but extend the transmission'south life.

But use the recommended fluid as noted in the owner's manual of your BMW. In most cases, you lot will need:

BMW Transmission Filter and Gasket Kit
ZF Lifeguard fluid - Or as recommended in the possessor's manual
4.5 qt if only draining oil pan
ix.5 qt for full arrangement affluent
Fluid Transfer Pump
Torx Socket
Bleed Pan

A BMW automated transmission holds about ix.5 qt of ATF fluid. Total organisation capacity includes all the oil in the transmission, oil pan, and torque converter. If you will non flush the whole arrangement but only drain the oil pan, you need most iv.five qt of oil.
