I have a ton of BG Automatic Transmission clean and I am due for transmission fluid and filter replacement. If possible i would like to do the fluid flush myself. I do not have a flush machine, but if I disconnect the return line on the transmission cooler and feed the transmission fluid to cycle through, I should be able to get all the fluid changed. Does anyone here do this? the reason I am doing this instead of going to the dealership is they were charging 200 for a transmission service and they don't even change the filter. my follow up question to this is should I use some of the BG ATC+ transmission cleaner before I change the filter and flush the system? I have had the jeep since 48,000 miles and I had the dealer do their transmission flush at 60k and 90k miles and I did the filter and what fluid was in the pan myself at 120k and replaced the factory pan with a PML pan. thanks in advance for the help.
