Transmission Flush Question

[MZ-N10]

i personally wouldnt feel like a flush is sufficient to a fluid/filter change. i mean the filter and the drain plug both catch alot of teh stuff floating around in there. if u dont change the filter, well then the stuff is still caught in teh filter.

Unless they've got little faeries in the flush machine to remove particulates from the filter it's just a bogus claim. Kinda like extended-interval oil. Sure, the oil may be good for a ton of miles but where does all the contaminants go?

[Tone]

I STRONGLY recommend the flush as it is the only way to change the fluid in the converter. Then I would add one of the new tranny filters I found at SEMA to filter down to 15 microns - the pan gasket only filters rocks 60 microns and larger. Filter is $25 and simply mounts in the tranny cooler line. It's not on my website yet but I have them ready to ship.

Tone, do you know if the 4L30E generates enough pressure to consistently flow through a 15 micron element? It'd be a good idea to upgrade the stock clamps and hose to avoid a line popping off or rupturing, just in case.

[Tone]

Filter has a bypass built in so it only filters a portion of the fluid each time to allow proper flow. Standard screw clamps are all that is needed. I spent a good deal of time with their engineers @ SEMA as it seems like such a simple but effective solution. There are other filters out there but they don't incorporate a bypass valve and use inferior filter media. Good question!

Hi,
Ive just had mine done, the full monty for $NZ375. There is a magnet in the JDM version that collects metal bits in the pan. I had about 5mm of metalic sludge on mine, something that my box can sure as hell do without.

Go for the pan removal, new filter, and flush.

Cheers.....

There is a magnet in the US version AND in this external filter. Realize that that metallic sludge ran through the tranny several times before getting trapped on that magnet and would have been caught by an external filter. I still recommend dropping the pan (especially if you have more than 30K miles on it) but far less often as this one takes smaller particles out of the fluid.
