So my old truck runs and shifts well and I'd like to be able to change out the fluid in the transmission more often than the filter. It doesn't have a lock-up torque converter so it is literally beating up the fluid at all times to get down the road. I have a suction device that can pull it out of the dipstick. Was thinking it would be easier to drop the pan, change the filter, change the pan gasket, adjust the bands, and then install a drain plug. I have always stayed away from this concept because it could loosen on me. Any thoughts? Something like the link I posted below basically:

Also, to keep it from loosening on me and/or leaking I am guessing Red Loctite would be a good idea on the threads of the adapter (not the drain plug itself).
