I just added auto rx to my transmission in my 1994 Subaru Legacy with 160k. My question is that the filter on the transmission is a screen literally, it basically had no contamination on it after so many miles (to my knowledge this is the original filter). The history of the car is that it had a 30k transmission service then nothing beyond. The fluid was dark and used up but doesn't seem burnt or heavily contaminated. I have changed it twice now so its basically new fluid with the auto rx, with each change The pan was clean no junk and not much clutch sludge even. So my question is does the filter need re-changed after the auto rx clean cycle and re-change of fluid. My point being im not sure what this filter is going to catch other than birds or squirrels in the oil.....the reason I ask is its a pain in the butt, the exhaust has to be removed to drop the pan, I just am not seeing this filter doing much of anything. Also on a side note the transmission is shifting fine, I am just doing this as a prevenative maintenance as I want it to stay that way if not shift even better.
Have your Auto-Rx Treatment drained out after 1000 miles using a T-Tec Machine or similar type unit. This will clean up torque converter and your screen plus refill with clean transmission fluid all at the same time.
Go to a Goodyear Oil Change or Shell even Jiffy Lube (last choice) don't let anyone upsell you on adding an additive to new fluid, not needed.
Within 150 miles after above done your transmission should feel like new.
( providing no broken parts) Auto-Rx can do no harm
