Question about 1997 Audi A4
Intermittently the display on the dash indicating "P,R,D,N,S" flashes and the gearbox selects neutral. After switching off/on a couple of times the display stabilises and the gearbox is ok and the car is drivable. At this stage the brake booster also disappears and the brakes react the same way as a manual vehicle with the engine switched off.
There is no computer for just the transmission. the main computer(ECM) use a TCM(transmission control module to run the solenoids inside the transmission valve body. there are several sensors accociated with the system starting with the engine speed sensor. To avoid any guess work there will be codes stored in the ecm and therefore needs a diagnostic scan done. you should take it to a shop that has this scan tool and not just a basic code reader. this is a sofisticated machine and must be done by a trained mechanic. he will have to check the parameters of the vehicle as well as find the faulty componant then clear the codes to make the vehicle perform as it should. this is not an easy fix... please rate this......thanks

I think it is something to do with the gear-box management computer...i would take it to a licenced mechanic and tell them the problem and have them fix it......probably going to be costly.....i dont believe there is a way to fix it yourself considering the complexity of this transmission and its components.
