HI Guys,It turns out that the 'Trans Failsafe Prog' error is actually a problem with the transmission.I got my e39 about 4 months back. Everything was ok until sudah bayar and took ownership of the car. I started getting the error which became almost daily after a couple of months. After exploring all the hopeful 'cheaper' options, I finally took it to our own Herbert Lai.Herbert convinced me that I needed to overhaul the tranny. According to him it was getting to a bad shape, got burnt parts and the trans failsafe prog was just doing its job to save me from a bigger problem.Anyways Herbet and his boys memang did a good job...and service also very good. I am very happy with the result...no more gong. Herbert also very happy cause he emptied out my wallet in the process. :top:He also psycho me a bit so now planning to do vanos seals, o2 sensor and the lights.
