Transmission problem! I need everyones help!

IzzE53 · #1 01-10-2009, 02:20 AM

Ok I have a 2005 4.4i with 45xxx, when I come to a rolling stop, I give it gas and BAM like a huge jerk and it feel like I got hit from behind! This does not happen all the time. I have taken it to the dealer, and they updated the tranny software, and deleted the adaptation values(learning codes for your driving style). They told me they can not replicate this problem, and that they need to see it happen for them to take care of it. What I need to know if anyone has had this happen to them? My warranty is about to run out and I need to find a solution. Please help!

If you can replicate it regularly, then when you go back to the dealer have the shop foreman ride along with you and show him. If the tech can't replicate it on test drive, then by you replicating it to the foreman he will make sure the tech fixes it.

I had the exact same problem with my 2005 4.4i at about 37,xxxkm and they replaced the tranny under warranty since they did not want to spend more time trying to replicate it and keep my x5 longer. I took it in one day for them to try and solve the problem again but they simply told me to take the x5 and said they'll give me a call when the new tranny is here. After getting my tranny replaced the rough jerk has never happened.

If you plan on keeping your x after the warranty runs out I would suggest getting another warranty cause trannies are expensive($5500-7K) to replace, but keep us updated.

Is the bang happening while the car is still warming up?

I have an '05 X5 3.0i and it does the same thing with 52K miles. Not all the time, but once in a while. I've only had it happen when it's cold, driving the first mile or so.

I'll take my foot off the gas and coast down a hill, then when I give it some gas again, I get the little "bump" in the transmission. Nothing terrible, but it made me wonder also. Mine had the trans software update before I bought it in Sept 08.

If you ever figure out what's happening with your transmission, make sure you post back here. I'm guess lots of us have that issue.

I had the same problem. The dealer gave me the same excuse (can't replicate problem). So I just kept bringing them the car literaly every Monday morning,it took 4 times but they finally acknowledge my problem and fixed it. They get tired of you coming back. They replaced my mechatronics also known as the valve body, and some gaskets although I'm not sure Wich ones. Good luck.

I kept bringing my x5 in and finally they just ordered a new transmission.

I have the same problem on my 04 4.4i. They did a software update on it back in 2006. After the update it didn't hit hard but it doesn't take off like it should on rolling stops.

If I recall correctly, the tech told me the transmission is trying to predict my next move and shift gears accordingly. If you come to a complete stop then it shifts down properly. At that time the X was new to me so I just took him at his word. Even if it is true, I have not had this issue in any other car I have own.

I hate to say it but this is the worst driving experience I have ever had. Because of it I have changed my driving habits. I now come to a complete stop before pressing on the gas. I think I will try a rolling stop tomorrow and press on the gas to see what happens. Since my X is no longer under any warranty there really isn't much I can do if the problem is there. I am not paying $4000 or more to fix this issue. I'll just have to live with it.
