Hi All,
My cars started coming up with a TRANS FAILSAFE PROG from time to time. Now what I find interesting about this is other than the car driving along as if it's slipping the clutch all the time (tq converter disabled?) it drives normally - goes up and down through the gears fine, and if I knock it across into manual mode I can go up and down through the gears without problem.
For the sake of completeness the car has had a strange issue since I got it - When I knock it across into manual mode instead of telling me I've gone into 'sport' mode, it lights up the 'Low' mountain. When I then go to change a gear instead of telling me I'm in manual mode it just shows the number of the gear I'm in, along with the low range mountain. Additionally when I put the car into low range it doesn't ask me to select neutral, it just waits until I've done so, and then the Low range mountain doesn't flash but you can hear the motor do something and when you drive off its quite clearly in low range, made obvious by the revs!!
Is it at all possible that these faults are related? I've read some things about the potentiometer on the transfer box motor... Could this be at fault? Or perhaps some kind of transmission ECU? I can't find anything quite like it having scoured the internet so I'm at a loss as to where to begin fault finding!!
From a gearbox point of view, its the only one I've driven so can't compare it to anything other than the L405 which i'm sure is completely different by design, but I think to me the gear changes feel ok. Perhaps a little clunky when cold but I've read that this is normal. Also possibly a tiny delay going from D to R and back again, but again I'd say this is only when cold, and doesn't clunk or anything just a small delay, half a second or so?
I had the car scanned today just after the TRANS FAILSAFE PROG came up, as I was on my way to my friends workshop anyway, and it said 'Mechanical Torque Converter Monitor Fault'
Not sure what this means and not sure I like the sound of it either Sad
Hope someone can help!
Cheers
Matt
