I've done replace clutch plate, seal (all repair kit) and solenoid but then 4F88 ( EGS (Electronic Transmission Control): ratio monitoring, gearshift 2-3 show up. In this situation, the transmission got lack of power which sometime like in N position and suddenly accelerate in bad condition.

2011年9月15日 · The transmission goes into failsafe mode with fault code 4F8D (ratio monitoring, gearshift 5-4 – plausibility) stored in the EGS. CAUSE EGS software diagnostics is too sensitive. This fault may occur during a 5-4 downshift only in vehicles with either low mileage, a replacement transmission, or after a reset of the adaptation values. CORRECTION

2019年10月17日 · EGS is your transmission control module, located inside the transmission as the electronic part of the mechatronics module. Hopefully that part isn't bad. The first thing to check is the electrical connection at the back of the transmission for oil that is interfering with the electrical contacts.

To flush the tranny, all you do is take the return line off the AT cooler and have someone turn on the engine. Drain the ATF from the return line into a marked (mark it by the QT) container. Once you get 3 qts out, stop the motor & fill up the pan with 3 qts.

2013年11月24日 · The EGS control unit looks at the input shaft speed sensor and the output shaft speed sensor to tell if the transmission clutches are slipping. This means the 2-3 clutch is slipping. This could be due to a sticking shift/pressure control solenoid or sticking piston is valve body.

Do you have a procedure to check the electrical plug? I am unable to locate any information on 4f84 or 4f88 on the service manuals.
