Read the thread above yours. That is the purpose of this thread.

People say transmission goes "kaaboom" immediately after changing your lifetime fluid.

understand now?

again, not trying to be rude....

But if that's what people say...

are you:

1) Deliberately changing transmission oil to see if what people say it's true?

or

2) Changing transmission oil to see if there are any performance gains?

i would love to do a transmission oil change too but im just too scared (41k miles right now) I'm just gonna hold onto my owners manual and if my tranmission goes because of lack of transmission oil change or whatever. I'm going to shove that "LIFETIME FLUID, NO FLUID CHANGE REQUIRED" bs down their throat!

Dude, stop trying to be "rude." Do a search and you will find the answer to your question. However, if you are too lazy to do a search, my answer is below:

OPTION 3. Lifetime fluid is BS. Nothing is lifetime. Oil breaks down. Changing your fluid is necessary to prolong your components.

Like I said, do a search.

The intent of this thread is to PROVIDE a series of updates so others members can view and submitt their data. Nothing more and nothing less. Nuff said

^^ agree with that. My friend changed the fluid in his automatic 540 the other weekend or so, and it had 100k+ on the clock. He hasn't complained about anything going kablooey yet.

I'd be interested in hearing updates every so often since my tranny feels like it's not catching gears as quickly anymore.

MINOR UPDATE:

I went and put my car up on a lift today to do a visual undercarriage inspection.

I checked for subframe tear. So far my car is good. What a relief.
I checked for exhaust leak on my TSE3. Small leaks. Maybe I should get it welded.

Anyhow, I noticed that I am having very minor transmission fluid leak around the gasket. I had to tighten it again with a t25 w/ a wrench. The bols actually made half to 3/4 of a full rotation. so my tips to you guys are make sure you tighten your bolts on your pan tightly. Hand tighten will not be enough force. Like I said, just a very small leak.

=)

Hmm.. I hadn't heard this. Its only on the Step though right? I'm planning on changing the fluid in my 325 5speed in a few weeks and got extra fluid to do it on my dads 330 step... Im guessing I might want to hold off then, or is the "kaboom" BS?

Below is the OFFICIAL instructions on how to change your transmission fluid.

I have the PDF document if you want it. The PDF document is from ZF (the transmission maker for the 5 speed steptronic transmission)


5HP19 General Transmission Oil Filling Procedure
Oil temperature should be between 86º…95ºF (30º…35ºC).
NO YES
Idle speed should be neng = 650 … 950 rpm (according to vehicle manufacturer’s directive).
Hold each gear for 3 seconds and engage the parking lock.
Select R and D and use step shift (manual-winter program) to shift through to 3rd gear.
Shift through gears with engine running at idle speed.
Start the engine (large consumers, such as A/C should be switched on).
With the engine stopped, add ATF, only use lubricants as to specification (see Page 3),
through the fill hole until oil emerges from fill hole. Install Fill Plug (Pos. 01.010/340).
Connect tester to read off transmission oil temperature and engine speed.
Position vehicle horizontally on hoist and apply the handbrake.
Shift through gears with engine at idle speed.
Depending on value allow oil to cool down or
warm up.
Continues on next page
Remove fill plug (Pos. 01.010/340) on housing.
Hold each gear for 3 seconds and engage
the parking lock.
Select R and D and use step shift (manualwinter
program) to shift through to 3rd gear.

NO YES
Allow time for excess oil to drip then install Fill Plug (Pos. 01.010/340). Torque Fill Plug to 35Nm ±3.5Nm

Here's what I've learned over the years, mostly with regard to domestics and japanese car, which may or may not apply. There are two types of transmission fluid services. A flush or a change. Generally speaking, a complete flush should only be performed on transmissions with less than 20k miles. If this is done early enough, consequent full flushes can be made at regular intervals, which vary by car make and model.

However, if a complete flush is not performed prior to 20k, then a complete should never be performed on that transmission. At regular intervals, a simple fluid changed should be performed by removing the pan and allowing the fluid to drain. Replace the filter and refill to the appropriate level.

After 20k, a significant amount of debris has been created by friction in the tranny. For the most part, this debris settles harmlessly in the nooks and crannies. Some will drain with the change, the rest will remain harmlessly in the trans. However, a flush will dislodge much of this debris, but may not force it out of the tranny. When the tranny is operated following the flush, large fragments may flow between the gears, causing damage or failure.

Sorry for the long post...

UPDATE 3:

For the last week I have been pushing my car extremely hard with the all spirit drives and a cruise I have participated in.

DATE: 30 MAY 2005
MILEAGE: 77,003 miles
Observation: After I retighten my bolts there are no more minor transmission leak. Also, there is no sign or smell of the transmission going bad. Maybe in a few weeks, I will lift my car up and try to conduct a ghetto oil analysis of my transmission fluid. Car is still running great.

Lastly, for those of you that missed it, here is the thread of the OFFICIAL Documentation regarding our ZF Transmission. Here you can find the specs, part numner, and official filling instruction on the ZF transmission:
