Hello I have a 2005 Chevy Tahoe I purchased used with 131000 miles on it I currently have 180000 on it now and I’m wanting to change the trans fluid when I first purchased it the trans fluid looked pretty good (so can I assume it was taking care of and properly changed?) now with 180000 miles the fluid is a little brown color pretty much like it looks changed my question is would it hurt to use the trans cooler line to pump the fluid out of the pan and add new fluid and filter back into the trans then flush the system again then add more fluid then flush again pretty much like a flush without using a flush machine would it be safe to do this this way because I’ve read where flush machines force new fluid backwards into the trans causing any build up to come loose would the way I want to do it be safe on a high mileage transmission?
