Hiya,im looking to get a pair of Xenon H7 HID Bulb Kit Holders Retainers Adapters for 1999 XJ,has anyone bought or knows where to buy them as I cant seem to find them ? And the previous set arrived a fews years ago and I was so exicted to get them on I used glue YES glue !! Lucky enough the bulb came away from the headlight,I honestly expected to renew the full headlight,so if anyone would be so kind to let me know where they got theirs {as the do not come with the kit?} or know where to get them id be very grateful as im NOT using glue again lol.They are on ebay for beemers item number is-400479028768 so that's the one except for a 1999 XJ
Thanks in advance

 

I had a great time, good crack and a spot on group of people. On the way home I decided to take a nice tour of Motherwell in search of Lorne sausage and Scottish plain bread ( get some every time I go up:-)) I also managed to avoid the portable cash machine ... sorry speed camera van ;-) someone must have told the police I was back lol. Looking forward to the next meet and getting the trans serviced at Mackies, that place had some equipment that's for sure!

 

Rab,

You'll most likely get a better response by asking this question in the X308 tech forum. Do you want me to move it for you?

Graham

 

Well done Jim.. you've pulled off a meet way beyond anything I could manage, great photo's, description of events and yes I would have loved to have been there :-) Very, very well done.

 

Mackie Automatic & Manual Transmissions remanufacture automatic and manual transmissions, gearboxes and torque converters for the public, dealerships and manufacturers.

They accept transmission units delivered to them or take complete vehicles where they will diagnose faults, remove, overhaul and refit the transmission.




Owing to the numbers attending, we were divided into three groups for our tour of the facility. Each group was able to see the three principal services offered by Mackie Automatic & Manual Transmissions:

1. Remanufacturing - Automatic Transmissions
2. Remanufacturing - Torque Convertors
3. Servicing, Diagnosis and Repair


1. Remanufacturing - Automatic Transmissions

The automatic transmission is totally dismantled and every component is cleaned and prepared for inspection.




From this point on, the entire process is scrupulously clean.




Each component (several hundred of them) is then examined and measured. All components that are not deemed 100% perfect are replaced.

All seals, gaskets, filters high failure components are discarded and replaced with new parts.






The valve body (control unit) goes through a process that includes ultra-sonic cleaning, vacuum testing, solenoid remanufacturing and final calibration on a unique valve body test station. This ensures that the valve body meets or exceeds the original manufacturer’s specification.




Following component checking, everything is laid out ready for rebuilding the valve body.




For those of us less familiar with the parts in the valve body, this graphic gives a clue to how it all goes together.







During the transmission assembly process, all sub-assemblies are pressure-tested to ensure total hydraulic integrity.




The remanufactured valve body is pressure tested




Each individual gear is subjected to testing. A loss on any one results in the valve body being put through the full strip, check and rebuild sequence again.




Final calibration with data acquisition is carried out on a unique valve body test station. This ensures that the valve body meets or exceeds the original manufacturer’s specification.




The subassembly is checked through all gear changes prior to final assembly.




The complete transmission assembly has a final build test on one of two road test simulators that create real life driving situations.




During this stage, the transmission is run at normal operating temperatures for several hours.




The simulator assesses every fundamental part of the remanufactured transmission. Any failed part will instantly be flagged on the test report.



This test procedure almost eliminates any potential failure prior to installation to the vehicle.

The equipment used by Mackie Automatic & Manual Transmissions is exactly the same as that used by the original manufacturers.

Remanufacturing Torque Converters

Mackie Automatic Transmissions torque converters are supplied with a life time warranty for the vehicle that they are installed in.

To start the process, the two welded halves of the converter are cut apart by specialist lathe operators.




After washing and examination, the unit is re-machined in one of three adapted high-specification lathes to refinish the joining faces.







Mackie Automatic Transmissions remanufacture torque convertors from the BW66 of the early 1970's through to the current 6HP26.



Through this period, the torque converter has developed from a simple 'fluid flywheel' through increasingly sophisticated 'lock up clutches'.





Note the two beakers on the workbench. The one on the right contains new transmission fluid. The one on the left has typical contaminated fluid from a transmission in for service.


Mackie Automatic Transmissions identify where there is a pattern in OE torque converters failures and develop improvements to increase reliability in their units.





The bonded friction lining is removed and a new one is re-bonded to the lock-up plate. This highly specialized process is made possible by a unique bonding machine.




The torque converter is welded back together, with accuracy to a few tenths of a thousandth of an inch.




The unit is leak tested to ensure the integrity of the weld is correct and rebalanced to meet or exceed the original manufacturer’s specifications.







This equipment test for glycol contamination. Not an applicable part of the process once a transmission has been stripped and cleaned.




The torque converter is shot-blasted to restore a perfect satin steel finish. A coating of anti-rust and an etching identification number is applied to the finished unit.




The remanufactured torque convertor is guaranteed for the life of the vehicle in which it is fitted.

Mackie Automatic Transmissions receive complete vehicles from dealers and individuals for everything from the standard fluid change through fault diagnostics and repair to complete transmission remanufacture.



Our host for the day, Managing Director of Mackie Automatic Transmissions, John Mackie explained that many automatic transmission issues are due to:

1. fluid overheating
2. fluid contamination (with engine coolant)
3. software

Autologic is their preferred diagnostics tool.



After retrieving stored and pending codes, these are cleared and the vehicle taken on a 5 to 8 mile drive. Any reset codes are used to diagnose faults.

Reflashing the TCM is a routine procedure and the latest updates are always applied.

Fluid changes are recommended at 25K miles intervals. This is considerably more frequent than most members are applying to their vehicles. A Hot Oil flushing machine is used.



The fluid lines are disconnected on the vehicle at the cooler and the fluid drained. It is then connected to the Hot Oil machine.



The remaining old fluid is pumped out and the transmission refilled with fresh fluid at the correct temperature and volume.

The tour finished with a summary from John Mackie and time for questions.



Not surprisingly, the difference between manufacturer's 'sealed for life' claims for automatic transmissions and Mackie's recommendation for 25K mile fluid changes raised some debate. It is the car manufacturer's (Jaguar included) who claim 'sealed for life'. The transmission manufacturers such as ZF recommend 60K mile fluid changes. John Mackie explained that a more frequent change significantly reduces wear and can more than double the life of an automatic transmission. Not a claim to be taken lightly when Mackie Automatic Transmissions guarantee their remanufactured products for a greater period than the OE manufacturers.

Superb Graham............As stated though, this is too good and will be lost here over time.

I suggest the post should have its own thread duplicated into perhaps the general tech help section, either that or we create a specific transmission section.

Thanks

Jim

 

Graham - excellent job on the photos/captions - look forward to seeing the rest of the process.

 

Agreed Jim - we need a central location for transmission info as it goes beyond Region or Model considerations.

Once the three parts are complete, I'll start a "Transmission" thread in General Tech Help.

MEETING ATTENDEES: anyone who has additional photos of the remanufacturing process covering details I have missed, please post in this thread or send them directly to me for inclusion.

Graham

 

My thoughts also were that it needs a separate thread.

I assume there was some discussion on fluids?

 

ZF Lifeguard 6

 

Hi Graham, I've opened a new "transmissions" section as you will see.

Please copy the posts into that section ( leaving the originals here ) and we'll see how that section goes.
Thanks

 

There was - as Jim has stated, they use ZF Lifeguard so no cutting corners or costs.

The recommended fluid change frequency came as a surprise to many.

Graham

 

Jim,

DONE - as a 'sticky'.

Hi Graham,
You are to be congratulated on an excellent and very comprehensive record of the Groups visit to Mackies Transmissions. Very well done indeed.
It will give other members of the Forum an understanding of the high standards that Mackies Transmission work too and indeed achieve.
Thanks for your great effort in recording this part of the days itinerary which I'm sure will be very useful to all Forum members.
Regards
Telfer.
