The 4-speed automatic transmission 4L30E is the successor of a reliable 3-speed transmission 3L30E, which has been used since 1969. These transmissions were made in the USA and in Europe (Strasbourg) under the name AR25 for RWD Opel Omega and AR35 for a 3-liter Katera.
The 4L30E has been installed since 1990 on RWD and AWD BMWs of all series with engine capacity of up to 3 liters, but it was more widely used on GM, Opel Omega, Isuzu and even on Honda Passport where it proved to be highly efficient.

Technical issues and repair guidelines
The torque converter, valve body and solenoids in the 4L30E transmission have a relatively limited resource. The operability of these components is gradually deteriorating because of the friction lock-up wear-out and accumulation of varnish in the narrowest places leading to the oil pressure drop and oil starvation, that results in a harmful impact on bushings, which have a proper resource.Operations with the worn-out pump liner and contaminated ATF lead to the oil pump damage. Plastic washer-bearings are also considered to be spare parts to be replaced.
The valve body after 200 thousand kilometers requires a statutory disassembly, repair and cleaning from varnish. The linear pressure solenoid was introduced in the valve body design for the brake band drive gear for regulation of the band pressure on the drum by means of PWM. Solenoids with exhausted resource are considered to be a typical problem in the electrical part of the transmission. The line pressure solenoid is also frequently replaced.
It is a reliable well-regulated transmission with a robust service resource for its components. After a simple overhaul this transmission can additionally operate for several years, if you properly monitor the ATF condition.
