2015年6月24日 · Things have been fine for about 5000 miles until again, transmission fault and failsafe mode - twice. I scanned again and it's the 4F83 code again. I have attached my screenshot from inpa. It seems like this only happened when cruising at highway speed (maybe only in normal D mode not DS), possibly on a downshift?

2018年7月10日 · In essence it is a sign of slippage of a clutch pack. This could be caused by worn pack or issues with fluid pressure that result in improper clamping. Fluid pressure could be a multitude of things: solenoids, cross-leaks in the mechatornics, the rubber seals between the mechatronics and the transmission body.

2023年1月14日 · Another option is to replace the solenoids and if that does not solve the issue, swap the complete valve body into a used transmission. Doing a swap that way does not require the transmission to be programmed to your car. These transmissions are tough and rarely fail. You should read out the adaptation values. x2 on checking the sleeves.

2019年6月24日 · A common code with BMW transmissions is 4F83 – ratio monitoring clutch c. This is usually a sign of bad things to come. Often times a “check transmission” or “service engine soon” light will also appear on the dash. The root cause of the fault code is a failure inside of the transmission itself.

These faults are most likely due to a software error. This will need to be fixed via a software update using a BMW dealer level diagnostic computer. Here is official BMW documentation on the errors: CLICK HERE TO DOWNLOAD DOCUMENT. I hope that is helpful, please let me know if you have further questions, or if I can clarify anything for you.

2024年11月22日 · There is a written process for resetting the adaptations on the ZF gearbox. Most of it is nearly impossible to follow on public roads but I would certainly make sure the gearbox is at operating temperatures before hitting the reset button in INPA. Well the code kept on coming back. Got a great price on a rebuild from an experienced shop.

2014年11月18日 · Any clutch problems inside an autobox means big bills.....get it to a dealer sharp! Assumed any work on the auto box would be quite steep, thank god it's still in warranty. It happened again last night and always seems to have around 4000 rpm above 70mph. Driving around town and steady driving is normal and car performs as it always has.
