Done many and never a problem. Vast improvement in transmission shifting. Shifting is much smoother and quicker, load or no load. If not sure, do not try to do it yourself. My .02 cents worth.
Any input is appreciated.
It's really quite easy on a tahoe or sub. I furnished my synthetic atf. I then went home and disconnected top cooler line to radiator from tranny. Fired up and within 15 - 20 seconds, a gallon has been emptied. Shut off and top off tranny with new atf and repeat again.
