156 2002 selesspeed conundrum
Appreciate if someone can help me. I love my car, but the Seles-speed gear problem drives me nuts. In a month, I would probably drive the car for 10 days, the remaining 20 days in the workshop.
I have undergone many selespeed gear problems, from not being able to shift, to not dropping, and have changed the gear box, the pump, the actuator. Recently for the past few weeks, I have a new problem. The console gear symbol will blink make beep sound, and that's it my gear wont shift beyond 2. By miracle if it shifts, it will shift up to 5, behave normally until the blinks comes out again.
My mechanic tells me my wiring is fried - feeding information to the ECU and controlling the gear change. And he is putting the blame on the sound system I have in the car. I run 2 amps, with big fuse block as well as many capacitors. Earth is grounded to the chassis. I don't really buy that story.
So I drove without turning on my system at all. A day was good, 2nd day the blink started slow and progressively increased to the point you cant shift.
The funny thing is, when I switch off and let the engine cool off until temperature to 50, everything works perfectly fine. I have even tried overheating the car by pushing the temperature to beyond 90, and it still worked fine.
Today I pushed the car ,blasted my sound system, drove fast the blinking never appeared..
hence my conundrum. I m tired off being weary of the gear change and constant trips to workshops..
I am noob when it comes to alfa, having owned the car from my brother. Spent a lot as driving it is a sheer pleasure..
