auto gearbox repair guidance

Recommended Posts

Hi,

 

You could DIY, but it'll be a massive job overall! 

 

Personally, I think with the sheer amount of problems your car seems to have, it's best to put it to the side and any money you would have wasted on it, to purchase a very good condition E39 and spend on keeping that tip top. 

 

The auto gearboxes will fail on these E39's, not a question of if, it's when. I went through 2 gearbox rebuilds and I'm now done with the hassle for when it goes next as I'm now a 5 speed manual, although I've got a relative few issues on my car, it's nowhere near the amount of problems you've asked about here and on the US forum over the last year or so?

 

Some years back, I think someone did post up about a DIY autobox overhaul and that guy I think had excellent mechanical experience, all tools and access, if I remember correctly, to a specialist service to clean internal component(s) prior to refitting. Also, any new parts were ordered from ZF in Germany.  If you want to go this route, then by all means do, but I suspect its going to be way past your skills level. 

 

Cheers, Dennis!

A huge job as others have said; best left to a pro IMO (unless you're confident of your own skills) and seeing how many other issues your car seems to have, unless the box is giving you issues, I'd personally leave it alone

 

A bit too much scaremongering from Dennis also IMO; there are a lot of E39s out there with their boxes in well over 150k/200k mikles, a lot in the States too, that have never been serviced and they give the owners no issues either!

 

Yes, they can fail, as can manual boxes etc... But to say that it WILL fail isn't the right thing to say IMO

 

Yes, a service for preventative maintenance isn't a bad idea and something I'd recommend; but it's still no guarantee that the box will be perfect thereafter

yah baby this is some propah porn 

i ve got a semi already

 

all it worries me is how to extract this damn thing... heavy beast

 

rest is easy... a couple of weeks of work and i am good as new

 

it takes few minutes to warm up the box when cold

 

and shifts are not butter smooth

 

 

Clav, you did box repairs before ,right?

 

 

 

what are the main components that wear out?

ie injectors need replacing teflon gasket, rubber seal, ball, and in some cases pin

I'll rephrase a bit then!

 

Given the numbers of autobox failures on the E39 in all the worlds territories they were sold in/are now in, time has shown that the gearboxes are a weak point when compared to the numbers produced. There are plenty that haven't had anything go wrong with them and are well over the 'usual' failure mileage of about 150K, but I suspect it's a relatively smaller number as compared to those boxes with either a total failure or torque converter issue at lower/much lower/similar/higher & much higher mileages. So, it's a much greater risk as time goes on that an autobox will have a failure. 

 

Compare with similar cars from Mercedes, and their autoboxes just keep going on and on..  and on!

 

Gine39530d - start a project thread for your DIY reconditioning job !

 

Cheers, Dennis!

Automatic transmission overhaul is never, ever going to be a diy overhaul, specialist tools, equipment, and knowledge required, either take it to the pro's, live with it, or scrap it, is the only way to go IMHO.

what equipment are you talking about?

i need big jacks or a lift

and a some sort of crane

and garages surface is not flat concrete

i am worried about logistics

 

you gotta believe in yourself

nobody is going to do it better than you

 

 

have you actually read this porn

http://pro-ht.mbnet.fi/Kuvat/automaattilaatikko/5L40E.pdf

 

?

 

there is nothing special

just bits and bobs that grind and rotate need to be replaced...

roughly 300 euros in parts...

extremely

expensive but worth it

i hate manuals

 

 

have you actually refurbished boxes yourself before?

any how, how much is to refurbish the box in uk now anyway?

By 'eck! It's a great write-up, but 40 pages just to disassemble the thing, and another 80-odd on how to get it back together? That would be enough to put me off! :lol:

While some of the tools (micrometer, vernier) are common enough I don't know how the average diy mechanic would come of with the 'mandatory' tools. Maybe some could be improvised, but an 'H gauge' in Fig. 189?  :o

you know these guys?

how much do they charge?

 

it is just I don't want to pay so called "high quality specialists"

 

for example injectors: in Lithuania so called "specialists" ask for 160 euros to refurbish one injector :D

a grand total of 1 000 Euros :D

and you have to send them these injectors by post and wait a week

when in fact it is a 5 euros in parts, or if a complete replacement then 40 euros max + 1 hour per each injector max

 

 

wtf is this thingy do?

how to improvise?

Hi gine39530d,

 

From your last response, it sounds as though you don't want to take it to specialists and that you want to DIY without reading manuals nor having the right tools, space as well. There's no point in reasoning with you so as I mentioned, start your own DIY Gearbox Refurbishment thread and post up, with pictures the entire project from start to finish. Post up about how and why you will do things, how and why you want to improvise and also perhaps total up all the parts you need along with any receipts etc. You'll perhaps be the 2nd or 3rd DIY project on this forum, so will be interesting to see how you go about doing things and for the relative small amount of money you currently think it'll cost in parts. What you can do, is also perhaps record the amount of hours you spend on the entire job for when it comes to the actual physical work and use that to a hourly labour rate a specialist would charge. 

 

Or, just put this car aside and get a well kept E39 instead. 

 

Cheers, Dennis!

but this thread is a beginning of an exciting box project :)

 

I recon it will take me 8 hours x 20 = 160 hours of hard labour and swearing

plus maybe days in ordering and waiting for parts and bits

 

how long does it take for a pro to fix box from a to z ?

3 days?

1 days disassemble

2 fix

3 put back

so 3 x 6 hours = 18 hours multiplied by ten due to my incompetence and asshands

I don't have a choice

I ain't got no money to blow on "specialists" also I live in very deep woods on the border with Belarus, far away from civilisation

All I have got is me

 

PS. how hard can it be? it is not like I am about to build a space ship or a CPU

I like to think I'm handy with a spanner and maybe just for sport and with a good workshop manual I would take a transmission apart in the garage just to study it but if I wanted a working gearbox, manual or auto, I would go to a specialist.

Trying to fix a car you rely on diy with a budget or deadline is simply not funny.

specialists are made, not born

and with my experience there are no bmw specialists around me

even here in saint peterburg these idiots took 7 days just to check DDE - OBD2 connection + 9000 Rubles :/ morons

 

and they are "certified" bmw specialists

 

alas but I'll do all by myself and much better with a help of this forum and Clav =)

 Sounds like the gearbox just needs a service to me, not a rebuild.

Gine will not sleep untill he puts that car to sleep forever.

 

Auto transmission work requires a high degree of engineering and specialist tools.... 

Best get a good second hand one from a low miler car and give it a service and it should serve you for many years.

 

By the way Ignalina isnt that remote... I was in Zarasai few years back...unless you opted to live off grid
