I've owned my 8 since 2017 and have had many great miles of getting to experience this very cool car. I believe the engine has many more miles as does the chassie. The auto trans is a zf 5hp-24 paired to the m62 4.4l v8 may be prone to early failure though. I ordered a used replacement from Quality Used Transmissions (used them before with good result). Unfortunately, the 5hp-30 was discontinued for the 840 in 1996 replaced with the shorter 24. I will have the mechatronics module upgraded with the pressure control valve from Sonnex. Any body have anything to add that may help with improving the 24 prior to install?
