Question about 1998 BMW Z3 Roadster

Faulty torque lock up in 4th gear

My 1997 automatic BMW z3 will not stay locked up in 4th gear going down the highway. The only time the transmission is locked up is under slight acceleration. After extended highway miles the check eng light illuminates indicating a torque lock up problem. Any ideas? Thanks Jim

2006 BMW 750 Li My dynamic drive inactive light came on, then a generator fault light came on


BMW has been using electronically controlled automatic transmissions in most models since the late 80s. These transmission systems employ a transmission control unit which controls electrical solenoids to manipulate the various control and shift valves and functions in the transmission valve body. When the transmission control unit detects a problem that it thinks could be damaging to the transmission or engine, it goes into a fail-safe or limp mode. In this mode, the transmission will function in reverse normally, but in forward it will operate in only one gear (whether you have the shifter in D, or any of the lower gears). This will typically be 3rd or 4th gear, depending on the model. It will start in this gear and stay in this gear with no shifting. You would experience this as sluggish acceleration and higher than normal engine speed at about 40 mph and above.

If you must drive the vehicle when the transmission is in the fail safe mode, accelerate gently and keep the road speed lower than full highway speed.

Earlier models do not employ fault codes and must be diagnosed manually. Late models do employ fault codes and a diagnostic/scan machine can be used to check and read the faults to assist in diagnostics. Note that this is not your common OBDII engine management fault code tool. This is what A BMW dealer or a properly equipped independent shop would have for full vehicle system diagnostics and coding operations.

What does the yellow cog light on the dash of my 1999 BMW Z3 mean?


The car is now quite old, and the yellow gear ("cog") light indicates that the hydraulic pressure in the transmission is incorrect. Check fluid level and, if the fluid is murky or off-color, have the transmission serviced and the filter replaced.

Sometimes the clutch pedal does not return, or sticks down, on my 1997 BMW Z3


You have air in the clutch system. Check the fluid level in the reservoir . Check for oil leaks at the slave cylinder ( replace if there is oil ) Have the system bled . IF you have fluid and the air comes back then replace the clutch master cylinder as the air will be bypassing the piston cup from blockages in the ports.

Is it normal for the automatic transmission on a 1996 Z3 to need to warm up before it shifts smoothly?


No, this is a situation that involves one or more of the shift solenoids that are inside the pan. These shift solenoids are malfunctioning at this time and, i recommend inspecting the transmission asap for faulty solenoids.

How to use overdrive button


Use it only on highways and you should wait until you are in 4th gear to turn it on. If used in a moutain area, it will put more strain on the transmission so make sure it is not on while going up hill.

Manual trans is stuck in 1 gear


This actually happened to me in my '91 taurus SHO. As they towed it off, the driver looked under the car, and noticed the gearshift linkage had slipped off. He reconnected it right there (no tools required other than we had the front of the car lifted off of the ground) and I drove home.
