Re: Gearbox Solenoid Change - Jerking Problem Solved - E90
Guys, I had the gearbox overhauled last year and everything was nice and dandy until I took a drive to KL last week.
While the jerking no longer bothered me, something else did. When the car went above 130 km/h for about 15 mins, the same dreaded red gear warning light came on. I had to stop the car, restart and continue on my journey below 120 km/h.
In SIN, most of us will not drive above 120 km/h so we may not know about this problem. Of course, you may or may not have this problem. If there is a chance, take your car to the NS highway and push it. See if this gear warning shows up.
I am going to take it back to my workshop and claim warranty for this "defect".

After overhaul ..... Safer to test by going on a dyno machine. Then can test until 250kmh and see if GB ok .....

Hi Bro Aaron,
Thanks for the info.
But I think my case is a bit different, please advice;
I'm having the same issue for my E90 2005 (Pre-LCI), I set aside for over 6 months & one day the "Red Gear" error popped out. But when I stopped the engine & re-start it, the Red Gear sign went off, until one day...... the Red Gear error appears and won't go off. So I went to BMW, they said this sign is reporting the gear-slip that happened, needed to be reset or upgrade the software. After they did it, the sign never appeared.
I also explained the jerking problem, they said the problem is on the "Mechatronic" (without checking it first). Now the jerking is getting worst; it becomes rougher every time I stopped the car. Because it's expensive, yesterday I to took my car to Triptonic Transmission Specialist Workshop, and surprisingly they sentenced; "it needed to be Overhauled". They're not mentioning the Mechatronic problem. Before, I was expecting just to change those solenoids; but it seems become a bigger problem.
Questions:
1. Is it possible that my gearbox is damaged, but the Mechatronic is fine?
2. Or should it be started by Mechatronic problem that caused damaged on the gearbox?
Many thanks before,
Jonathan.

Alamak,
if I have known earlier, would have bought my own ATF oil and oil pan to the workshop.
was charged 7 X $35 & Oil Pan $215.
difference of $98+$55=$153!
However, would they then charge labour of $300 instead of $150 if i BYO?
