A quick update.
Although I bought the VB kit a while back, I didn't have the time to do it yet. But, I also bought a tranny that has a delay to engage in D (I drove it before) for a few hundreds with 125k km. I swapped only the VB last night and the gears shift so smooth but I still have the lurch from 2-1st unfortunately. I also get the shudder once in a while. The lurch was reduced a lot after a firmware update and I thought swapping VB will get rid of it completely. I used ZF lifeguard.
The plan is to rebuild the spare tranny and do the VB soon now that the weather is better.
BTW... problems never end. I also need to replace the front axels and all wheel bearings.

Can the whine I am getting at 2000rpm be the torque converter?

When driving, at 2k rpm, every gear I get a steady whine. If I go below 2k rpm, or above 2k rpm, it goes away.

I took a long drive on Sunday, the whine went away about 30 min into the drive. It came back after the car stood for 6 hours. And again went away 30 min into the drive home.

It will whine at 2k rpm in neutral and park as well, much less noticeable, I am guessing due to no load.

Had this since day one of owning the car.

Please advise if you can. Thanks.


newbie here have the same issues...mine is 2001 4.4, after seeing 2 different indie shops both came up with different guess.

1 indie said it is the TC, other one said it is the transmission pump. Need Advise do i need to replace both TC and Pump, or is it the flow spring phil mentioned?

I am now thinking output shaft bearing on the transfer case. My actuator failed once and became rear wheel drive. Noise went away. Saw someone else have similar diagnoses. I'll pull that bastard off one of these days.

Hi eevrybody, been away in the work world lately.

My original trans just turned 155,000 miles. at like 153,000 the thing stated to do the engine fail safe thing, activated when I would press the gas pedal quick like. So I took it to the indie and he says it's time for a new tranny.

All the blood drained out of my head. So, I took it to trhe BMW dealer. I had 3 vacum leaks that were sending false codes and flipping the e f s switch.

they fixed the vacum leaks and it has been running like brand new for the last 1500 miles , no codes nothing.

To infinity and beyond!!!!

How 'bout nothing's wrong.

Maybe it aint over til the fat lady sings.
Maybe the indies aren't as smart as we think they are.
Maybe you change the fluid and the filter every 30,000 like me and see what happens.
And maybe it goes in the next 10,000 miles :dunno:

I have codes 49,52 and 59. I hate these transmissions! Is there an easy fix for this? Obviously it is an electrical problem or there would not be any codes so what should I look at first?
49- Symptom gear check
52-gear check 2
59 stalling speed...

That is an incorrect assumption. The code doesn't say what is wrong, it simply reports that something is out of range. That could be a hydraulic or mechanical problem, causing a sensor to report a problem.

The problem (for me) was that BMW seems to see the transmission as one piece which they do not repair. They only replace it.

Are you having only that codes or some special probs with your transmission like rattling sound, hard shifts, .........?

Good luck,

Helmuth
