I saw on a couple of posts people talking about a exterior transmission filter. Mine does not have this. When I was installing my transmission cooler. I saw just the two lines coming out from under the car. I removed them, Then put longer ones on so they would reach the cooler. Could I mount a spin on filter somewhere between the cooler and trans?

Yeah, these are standard only on the 1994 and later with the twin heat exchange tanks in the radiator.

These cars even in stock form had much longer lived transmissions than the earlier non-filtered single heat exchange tank designs.

Study a 1994+ FSM.

Thanks, I'll have to look up a FSM. Would a filter hurt flow at all?

Not if it is oil filter sized as the Q transmission has relatively low pressure thru the heat exchanger ---- usually under 40 psi...........and a quality filter has an internal bypass flipper valve which open closed and above X psi.

Careful some filter bypass open at 8 psi and some at 17 psi DIFFERENTIAL PSI.

Consider a Pure One Filter element...............a long large one

I ended up mounting mine on the driver's side front bumper bracket - Makes it easy to remove without making a mess.



I took some pressure measurements (link to thread here) - the spin-on filter added no extra back-pressure. At least on the Y33, the original in-tank cooler by itself is more restrictive than an external cooler and spin-on filter combined.

I was going to put one on my G50 but as much as I love spin on filters, I don't want to waste all that expensive fluid... I guess what I need to know is how often you change those filters and if it would be worth the price of the extra quart of syn fluid every time you do.

I would think it would be worth it. Mainly because you dont have to drop the pan. Well, You do to drain the fluid. I would change the filter every 12,000 miles then add a extra quart. then after 30,000 miles, drop the pan and replace all of the fluid. Might even be worth installing some kind of drain plug on the pan.

I have an extra pan with OEM drain plug if anyone is interested.

easy way to add a filter is to just splice in a MAGNAFINE inline disposable filter in the existing cooler line
