Let me tell you about my experience with Wally World ATF+4. I did a trans filter change on my 03 T&C minivan and used the Wally World trans fluid. I had all kinds of jerky upshifts and downshifts. I thought the filter was not on correct and sucking air. I dropped the trans pan again and found the filter was fine. Still had shift issues so I changed the shift solenoid pack. Still had jerky shifts. Then I drained out the Wally World oil and replaced it with Valvoline. Trans shifted smoothly immediately and has been just fine for the last 2 years. I bought the wally fluid because it was cheaper but it really cost me in the long run.
