Second time the converter failed the whining noise was only in 1st and 2nd and gradually got worse.
Third time started getting the jerk 2 weeks later.

2) My last issue seemed very similar as I posted above.

3) I had the tranny rebuilt along with the converter for $3,300. The last two times have been warranty work so no cost. Shop says its $300 to rebuild converter but this doesn't include R&R.

4) Not sure what you mean here, but if I was traveling an upgrade jerking would happen if I was light on the throttle, normal driving.

As far as a lose of power in my case it is minimal and gradual. Became very evident when the converter was replaced.

Hope this helps.

Thank you very much for your time to answer all of these questions. I do believe that are issues are pretty close. Not exact, but you have the jerking, at the same speed, and you could stop the jerking by adding more throttle. which is what we are experiancing. Yours did have more of a pronounced whine, where mine sounds more like a fan/blowing air then a whine like that. (reminds me of a Isuzu Trooper, they always had a whooshing fan/air sound, instead of a exhaust note).

I believe that I will have the Torque Converter replace a long with the valve body.

Again thank you for your help in this matter

why bother replacing anything when you don`t have a serious problem .?

maybe nothing wrong with the transmission , you read Patrick Irish thread about the battery , not the first time I have read a similar story .
If it aint broke don`t fix it .

No....

Ok, looked it up.... I even posted in it. lol.

Amacman.... I want to thank you for keeping me from impulsing and just throwing money at this thing! So thanks for helping me to just slow down and think it through.

Well I read all of the recent post and read about the one that posted a link to a diffrent one. I read that too.

I looked at my battery and sure enough it's not a BMW battery. I don't know yet if it is equivalent to the org. but will look that up now and post some answers. Here is what I have.

As I am crossing my fingers.

Ok looked up my battery, and it is what Interstate battery says I should have. It looks some what new and I am again in the dumps as I was hoping it would be the problem.

Ugg, back to high dollar plan?

I am not convinced about replacing the torque converter or valve body as a fix
Hit Redline and others have gone down that route to no avail .
Patrick Irish may , as he says , have reset the computer by having power disconnected for a time , others tell a similar story .
I have no idea , of course , how serious the issue is on your car but think back a week or so to where I said I also have slight hesitation but only when A/C is on .
I think these cars have , for want of a better expression , electronic tantrums sometimes .
maybe it`s bad signals caused by a bad connector .
a buddy of mine had issues with a ZF transmission on a VW going into failsafe mode and no one could find any problem .
I simply asked him some questions about the when and where it happens , turns out he drives through puddles whenever it rains so a clean up and grease up of some connectors and it`s good as new for a while but he won`t stop driving through puddles .
he drives high miles in his job so a few months later the problem is back .
anyhoo , just saying , cool yer jets and look at the simpler solutions before you spend a lot of cash .
good luck .

Dinan E39 - symptoms sound like the mechatronic module. Search for that here. I had mine replaced last fall and it took care of the similar issues I was having.
