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

My 2000 hyundai elantra is automatic it has a code p0734. which the mechanic explained me that i have to get the speen sensor replace and get new clutch because the 4 gear ratio is bad. pls advice what 2...


P0734=A/T 4th gear incorrect ratio. This has nothing to do with the speed sensor. If the speed sensor was faulty, it would also set OTHER gear incorrect ratio codes. My experience tells me the 4th gear incorrect ration indicates the torque converter clutch (TCC) is slipping and nothing more. Unless there was a speed sensor DTC (Diagnostic Trouble Code), the sensor is not the issue (yet). The fact P0734 was set (trust the computer), the TCC is slipping (out of range). Question: Maintenance history may indicate the wrong transmission fluid may have been introduced. Hyundai's Transmission fluid is strictly SPIII... there is no substitute. The incorrect fluid will cause 4th gear slippage. Now, having said that, it doesn't mean the 4th gear (lock-up) clutch isn't worn out. Have a qualified/certified Hyundai Service Technician properly diagnose this issue.

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.

Trans drops into 3rd gear won,t shift to 4th


DTC P0734 is "4th gear incorrect ratio" - that's your torque converter 'LOCK UP Clutch" It's worn out (or you're using the wrong Trans Fluid required by Hyundai - SPIII OR Both). The P1624 is simply the Trans Control Unit (computer) communicating to the Engine Control Module (ECM computer) MIL - on request signal to ECM = asking it to turn on "Check Engine" light. MIL = Malfunction Indicator Lamp. When the torque converter 'lock up" clutch slips or doesn't engage, the trans automatically returns to 3rd gear and stays there (it's called 'fail safe' mode) until you cycle the ignition key, then everything resets until the malfunction occurs again.
You'll need to have an AT (Automatic Transaxel) tester hooked up to verify this. Hyundai has a Service Bulletin specifically for "gear incorrect ratio' codes. If when you changed the trans fluid, was it done at a Hyundai Service Center? If not, someone may have installed the wrong fluid.

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.
