Is there any issue for running the clean period for around 10,000k's in a 4L60E auto transmission ? Will auto-rx do any damage to the materials, or bands etc ? THanks
If the transmission is spotless clean I would have no problem running ARX in the transmission for much longer than the 1000 miles. But the only way to verify a spotless tranny is to tear down. So in reality I advise that the stock instructions is the way to go. I personally would not exceed 500 miles. Thank you for purchasing ARX.
I hope this will help you. I would not go 10,000 miles.
During a normal application while ARX dissolves the oxidized fluid deposits, some gear filings or overdrive clutch wear deposits may be attached to the oil deposits, which will become liberated, as the oil phase is dissolved.
The application for an automatic transmission of a passenger car or light truck is to run the 6 fluid ounces for 1000 miles before purging the old fluid out with new fluid. This will guarantee that all deposits are suspended in the old fluid before purging. It is not advisable to add the 6 fluid ounces and run for 30,000 miles in a transmission that may be dirty. Filtration is somewhat non existent in many automatic transmissions, other than a small magnet. It is not advised to circulate dirty fluid much longer than the recommended 1000 miles.
If you were to attempt to run much longer than the recommended 1000 miles with Auto-Rx in there, at least install an inline filter such as a Magnefine to one of the cooler lines to provide some real filtration of the fluid, preventing continuous circulation of particles such as wear metals or dirt.
A Magnefine filter in one of the cooler lines will typically filter at about the 25 micron level (and has it's own magnet inside too), while the (suction side) filter inside the pan is there mainly to catch the big stuff and protect the pump from damage, and filters at about 100 microns or greater, which is not much filtration at all.
