It depends on your car model, go to a specialist shop for your make, most large shops will have it.

If it is an automatic, if the transmission fluid hasn't been changed for a while (say 5 years), chances are the clean fluid will ruin it, as the particulate in the current fluid might be holding it together from failure. So consider that before you go berate the shop.

As for machine shops. Alecs in Vancouver and High Performance in Burnaby are good shops. Personally I rather do it myself on a milling machine.

In future, please make sure your titles are actually indicative of what you want in the thread.

Godwin, your telling me that shitty 5 year old auto tyranny fluid is better than swapping in a fresh batch of fluid and a new pan filter? That the transmission will fail if i do so?

Come on man.

Lifetime fluid for the win.

godwin · 05-07-2013, 01:16 PM

Actually that's a common point of failure.. look up e36 or old Mercedes forums.

It is just like people blaming switching to synthetic causes oil leak problem. Older transmissions a lot of the times are held together by the gunk and varnish that have been accumulated. Yes bcrdukes especially "lifetime transmission" fluid, as most car manufacturers define lifetime as 15 years (that's when they are mandated to keep parts in stock for).

I say transmission flush doesn't solve transmission issues you might have in fact it will amplify the issues (like leaky seals etc).. it occurs more on automatics because they tend on rely on hydraulic pressure.

I am saying if you transmission doesn't have regular maintenance, a flush will probably make things worse.

Also I am going on the track record the OP has.. ie his recording to his friend's wheel shop etc.

Especially in the BMW's that use GM transmissions and E46s in general, by the time the tranny hits 150k without a flush, you are better off just leaving it in there than putting in new fluid. If you do flush really old fluid there's a good chance there will be gear slippage and shifting issues.

Kinda damned if you do, damned if you don't.

OP, If your car is a MANUAL i would reccomend it, If it's an auto i would say don't do it... I had a trans flush done in my old Maxima and had nothing but problems after.

Drain and refill. Don't flush.

narfy · 05-07-2013, 02:25 PM

if it's an automatic, i'd just do drain and fills every time you do an engine oil change and gradually, the fluid will get cleaner and cleaner... if you do opt to do a machine flush, DO NOT PUT CHEMICALS INTO THE TRANSMISSION or specifically request the shop to NOT put cleaners/chemiclas in prior to the flush... that will loosen any bits of gumming, crud, dirt and crap and that will ruin your transmission... if you only do a fluid exchange, ur chances of issues is much less...

i would just do a drain and fill every oil change until the fluid is clean... it takes a lot more fluid, but the chances of damage is greatly reduced...

320icar · 05-07-2013, 04:59 PM

I think there is confusion in this thread. Obviously do not use a chemical "tranny flush" like you would in engine oil.

There are two ways to switch out auto tranny fluid. The old drain and fill, which only gets about half the fluid since there is still fluid in the lines and pumps etc. or a proper automatic transmission fluid flush, which is a machine tha uses the auto lines (usually tapped into where the lines go into the auto tranny fluid cooler inside the radiator) and uses the hydraulic pressure to push in the new fresh fluid while the old fluid gets flushed through the lines and out, into the machine. Most places like a mr.lube should have this machine and it DOES NOT HURT an older transmission.

Again, do not use a chemical "flush agent" in an auto trang. But DO use the correct tools and equipment to change your fluid

I think he drives a g35? 1st of why do you think you need it? Having issues? How many Kms on tranny and how many Kms since last tranny flush? More info would be helpful

Wow when is that 'transmission flushes kill your transmission' myth going to die?

Transmissions fail after they're flushed because people wait until their transmission has problems before they flush it, it was about to die anyway. The flush didn't cause it.

Read closely what I said in the second post!

Transmission flushes are an important part of maintenance on most automatic cars, one that nearly all owners neglect until it's too late. That is why they have a bad rep, period.

skylinergtr · 05-08-2013, 07:02 AM

don't use any flush machines.

Just drop the pan and replace the filter/gasket (if applicable). This is the best way to do a transmission service.

You will replace more than 50% of the fluid usually, and just keep up with maintenance and do a drain/fill every year.

BlueSedanRUS · 05-08-2013, 08:03 AM

Ill be more detailed next time.
The shop that did auto body work on my car, measured AT fluid level by the hot side when the oil was cold, so the outcome is, oil was overfilled by 2 quarts and smells burned.
I am not looking for a *chemical* flush, need a shop that will flush all the oil out of the converter and etc.
Buy ill probably take the advice and slowly drain and fill it, ill just use the ruturn lines from the AT cooler.

P.s there is about 3 quarts in the pan, total is 10.

This right here is the best way, IMO.

Just make sure you look up torque specs for any bolts inside the transmission itself and be very careful to retain all rubber washers where applicable.

Then re-assemble and fill through the transmission dipstick.

Thank, anyone has input on inline tranamission filters?

If you're going to use one it's critical that you remember to replace it when necessary. If it gets blocked, there is no bypass so you'll cook your transmission in short order.
