Spin-on transmission filter

After a bit of reading, I'm thinking about adding a filter to my transmission's cooling line.

From what I understand, it has a 15psi bypass valve in the mount in case the media gets clogged up. I guess I can just re-route the return line on my transmission cooler to pass through this filter assembly before entering the transmission itself. Are there any possible downsides to using this setup?

The car is a 1993 Nissan Sentra XE automatic.

Why add an extra filter to a very ordinary car that already has a well sorted gear box?

I dunno. I've always been told nothing but bad things about stock ATF filtration, and I don't see why I should just let all the wear metal float around in my gears. But, I suppose regular fluid changes could help that.

It also gives me somewhere to add a temperature sensor. Not that I really need one, but I like to know what's going on in there :grinyes:.

If it was a race car, or a performance built street car, then I could understand the need for one.

But an XE Sentra isn't exactly Nissan's idea of a performance car.
The gearbox will be running well with in its design limits, and as long as its serviced when it should be, it should out last the rest of the car.

Adding extra bits to it, that are unnecessary only adds complications, it takes the design outside its intended uses, all of which can actually effect reliability.

if it needed a filter, Nissan would've given it one.

, and I don't see why I should just let all the wear metal float around in my gears.
Next time you service the trans and drop the pan, make sure there is a magnet inside the pan. Often, mechanics throw this magnet away instead of cleaning and reusing it.
It is surprising how much of the debris in a transmission is magnetic (usually worn clutch friction material) and will be caught by this.

If it ain't broke, don't fix it.
