Exclamation 2002 X5 4.6is transmission issues

I recently purchased my X5 knowing it had transmission issues which could result in a total rebuild but before going that far maybe someone can enlighten me with other options? Shifts smooth when cold but as things heat up the downshift from 2nd to 1st is quite abrupt. Also, there is an occasional shudder when upshifting from 2nd-3rd or 3rd-4th. Doesn't seem to be an issue in sport mode or manual shifts. Could it be as simple as a drain, filter,etc. service? It is 5HP24 tranny. Thanks everyone!

I'll take it to ZF tranny specialist, get the fluid level checked and see if they can diagnose on temp sensor inside the tranny. At least before you spend money on full tranny.

Could possibly be the oil cooler thermostat or the oilcooler itself, id check these out first, then look at the one way clutch,

Transmission repair

Hi Mate

I stripped the gearbox down myself, and replaced the one way clutch witch was all but gone, I replaced the main hub in the gearbox, refilled with new oil and changed the oil cooler, all in all I was 500 hundred for the parts and it took 8 hours to remove the box, a further 8 hours to refurb the clutch and hub ring and then the fitting was a day, a cheaper and better option than the stupid prices I was getting quoted for a rebuild which was not required, send me a note to decscribe what problems you are having

Cheers
Gerry

Hi

My problems were apparent when the car had warmed up. It was unable to drop down into any low gear which made it sluggish to pull away. When i do pull away it is usually in high revs and then a almighty thump as it engages gear from the rear axle. After continued driving it ceases to even thump in gear and is now stuck in either 3rd or 4th gear. It is not possible to select manual drive when this happens. To drive it any at all i start off when cold in manual and leave it in third gear. I was also told that this is a problem with the transfer box which is quite expensive.I hope that there is a cheaper option than a new one.

Hi Mate

Sounds identical to the problem I had, will your car reverse ok, I take it you loose kickdown on any gears once she thumps into gear, being stuck in high gear means the computer doesnt recogonise the gearbox functions from one to three, gears four and five are not computer controlled so therefore they are the only two gears that are available and the car automatically puts you into 5th gear in what is called a limp home mode, this gear can be driven around town all day but puts strain on your engine as you have to pull away in high gear.

I would hedge my bets that your clutch is gone, as this was the same with me, most people say a re-build is needed but this to me is a con as a re-build can accomodate a new clutch and hub ring, how is your mechanical skills, if you are handy, test something out, drain a little fluid from the box, it is quite easy to remove the nut without taking it off completely and get a plastiic cup and drop a little oil in to it, look for any metal sheerings, the oil will most probably be of a burnt smell and colour, this indicates that the oil cooler is in overdrive as it cannot sustain the pressure to cool the oil down due to the gear selection problem and the car being stuck in high gear,

The prices I checked for a replacement box were around 1400 -1600, I decide to strip my box and found the problem was with my one way clutch.

All in all with doing the job myself I spent around 500 for the parts and three days off my time, if you are not handy, try taking it to a mechanic to see if he can drop your box for you and he will see straight away if the clutch has gone.

Hope this help, if you need any further info just give me a shout

Cheers
Gerry

Cheers for the information Gerry. I can still drive in reverse which i think would indicate that the clutch is fine however i will stillcheck that out. I was contemplating doing the job myself. even to rebuilding the transfer box which i found the parts on a site called Cobra transmissons.(have you heard of them?) I was told that rebuilding the box was not available but i could not believe that as with all gearing and seals must be able to be repaired.Tthat was the main reason i sort opinions from other sources and this site as been a great help, which you have proved. I will let you know the outcome of the oil condition and other findings to help pin point the fault. As with all things in life we are trying to get the best done for as litle as possible in the way of prices. I adore my car and i dont really want to part with it for sake of high maintenance fees. But with everything there is a limit.

Hi Mate

As you have indicated you can reverse ok, then i,m a hundred per cent certain your one way clutch has gone, what is your current mileage, I doubt very much your box will need a re-build, I had 5 different people telling me i needed a re-build and they were all auto gearbox specialists, a new one clutch and fresh oil, and oil cooler sorted the problem out, most people I know with this problem tend to go with the notion of the advice of specialists on a re-build, sometimes but not very often if you drop the pan and change the oil and filter ( easy job ) this can sometimes sovle some of the symtoms you are experiencing, as the filter gets clogged up and cant breath to cool the oil down, as I said earlier you will be able to tell if you drain a little oil from the box and check for any metal sheerings wich would indicate damage to the box and therefore a staright answer is in a re-build, if no sheerings are found but the oil is of a burnt nature then I would risk dropping the box and check the clutch and torque converter, the torque converter has a unit in the middle called a stator which distributes the fluid around the box, the stator is controlled by the one way clutch and if the oil is not getting to gears one to three then the box shuts down and goes straight to high gear, your torque converter wil be trying hard to drive the car but the clutch will not work in sync with the stator because of wear to it.

Mind let me know how you go with this

Gerry

That information is good enough for me. my mileage is only 60k. So Im going to go with the one way clutch and fresh oil. Along with the stator i will inspect them for wear.

Thanks Gerry i will let you know how i get on.

Hi BC

60K your mileage, have you driven the car hard, by that I mean use its power, I can honestly say I doubt it very much your box is shot, I changed mine at 100k, and the guy I bought it from went off road with it for three years and really pushed the car hard, BMW say the gearbox is lifetime filled with oil, but if you look closer to their facts the say the lifetime of a x5 is 100k, one other thing to check is at the bottom of the radiator there is a shroud housing that holds a thermostat for the gearbox oil, that may need replacing as well along with the new oil, mind have a look at your oil cooler for any debris in the cones, the oil itself for the gearbox is around 90 quid, the only alternative to BMW's gearbox oil I would look at is mobil or ATP trans fluid.

I wish you good luck with this

Mind you know where Iam if you need any further help

Cheers
G

I must admit i do use what power there is im afraid. Itend to do a lot of motorwaydriving and i generally keep up with traffic thats going a little quicker than normal.. I do remeber when the problem arrived and it was fair to say that i was in a rush and kicked down at high speeds to gain more accelaration to hasten my arrival. Does this change the perspective of the fault.

No it just increases my opinion that the one way clutch has packed in, have you lost kickdown altogether?

I have not tried the kickdown due to the gearing condititon will this confirm it that it is the one way clutch.
Thanks

I had the same problem and had to have mines rebuild, once a tranny starts acting up and its not fluids you should have it checked out asap before it becomes a disaster. my problem was a broker bearing that resulted in a 3500 dollar fix

Hi, sounds similar to problem I had. Sharp downshift as I came to a stop. If this is what you have then this will interest you. My problem went from a harsh downshift to just about a thump.
a BMW service center said I need a new transmission. I didn't swallow it - so they perfomed a computor check..( sorry I'm not mechanically minded, terminology etc.. ) it didn't help and confirmed a new trans would fix it. Not satisfied and having read and followed suggestions from this forum I went to another BMW Service center further away from my locality - They did a similar thing and suggested I need a new Trans. They didn't know I was at a different dealer some weeks back. When I was driving home the harshness was alot worse.
Contacting the service manager with a letter of dissapointment and giving me wrong diagnoses something like"I believe all you want is to pit a new trans .. You actually made the situation worse, if that's the case I believe you can fix it.... As I read about similar problems all over the world.... ) The service manager called me, agreedto an extent and suggested they update the software at no charge. They did and the problem is gone. been good and has been about 6 months. all the best.
