Nothing can beat the high-end design, impeccable engineering, and longevity of BMW vehicles. However, like every other vehicle, they too require regular maintenance to retain their superior performance. Not committing to routine maintenance can even result in unpredictable issues requiring costly repairs.
The bulk of BMW issues relate to its transmission. If you don’t opt for transmission repairs in a timely manner, it can develop serious problems over time, requiring a complete replacement.
Let’s take a look at some common transmission problems specific to different BMW models:
Common Transmission Issues with BMW 3 and 5 Series
The 3 Series and 5 Series BMWs feature 5-Speed ZF transmission. The most common problems associated with this transmission type pertain to the torque converter delamination. BMWs subject to this problem appear to misfire or shudder when the vehicle hits the speed of 40 to 50 km/h. You must address the issue when the earliest signs appear. Procrastinating on repairs can cause the converter lining to fail, destroying the transmission’s entire pump assembly. The automatic transmission will then have to be completely reconditioned.
Another common issue with the 5-speed BMW transmissions is the break down of its D/G cylinder, which causes the vehicle to lose its reverse gear. Again, repairing this problem requires a complete transmission overhaul.
Common Transmission Problems with BMW 7 Series
Models of BMW 7 Series manufactured after 2003 have been subject to faults related to the valve body and mechatronic faults in the automatic transmission. Some of the symptoms of these problems include:
- Roll down faults when shifting from second gear to the first
- Slippage when shiftingfrom third gear to the fourth
- Tough engagement when shiftingfrom N to D
- Switching to failsafe mode and limp home mode in one gear
These models also face the torque convertor faults discussed earlier for BMW 3 and 5 Series.
Common Transmission Problems for Imported BMW Models
Most automatic transmission problems specific to imported BMWs result from faulty internal seals. This happens when the rubber loses its pliability and becomes brittle and rock hard after facing heat in Asian countries. The ineffective rubber seals lead to leakages appearing in the form of automatic transmission issues.
In their diesel models, BMW typically uses the GM transmission 5040E, a transmission that has suffered a lot of problems and undergone multiple upgrades over the years. Some common auto transmission problems in BMW diesel models include valve body deterioration, loss of reverse gear, lining delamination, and converter failure.
These problems often require extensive valve body upgrades and replacement of mould pistons and all friction plates.
