So I finally got around to changing my transmission fluid on 04/21/2018 with 150,000 miles on it. I only went through the cooler lines due to the transmission pan having a good amount of rust built up on it around half of the bolts. I didn't have a new pan at the time so I wasn't risking pulling it off and it not sealing later. Anyway, this fluid was very bad. When I pulled the line I second guessed myself if it was an engine oil cooler line. The way I did the job was I used an electrical oil excavating pump to push the fluid in the transmission. I would have the car in neutral and then start it, let it run till the steady stream of old fluid started sputtering, and then turn it off to let the electric pump catch up. I didn't check the level after doing everything because I compared the two buckets I used to do the job. I marked the new bucket at 12 quarts, and I stopped pumping fluid out of the car when the dirty bucket hit the 12 quarts mark. As far as the results go I have to start by saying my rumble strip issue was pretty bad, I had to have it in 4th gear all the time until I got up to 50mph. After doing the flush it was still shaking but its getting better as I put the miles on it. It just hit 50 miles since the change and it is way better. Once the new Valvoline Maxlife ATF has a chance to completely wash all of the parts I'm sure it will stop shaking altogether. Also this job doesn't clean out the cooler so some old fluid was still in there, and now the new fluid should help clean the cooler as well. After I know the shaking is gone, and I have put around 5,000 miles on the new fluid I will be switching over to AMSOIL. On the second flush I will replace the transmission pan, filter/screen mesh, and the cooler elbows going into the housing (rusty :-/ ).
When replying to you before I missed where you stated you had the shudder issue, I would highly recommend adding a tube of Shudder Fixx additive now as well as when you do the fluid exchange again, it does wonders for the shuddering and just overall very good for the torque conventer which is where the shudder comes from, you can find this at most good auto parts stores or order online!!
