I actually wonder what the PSI is of those flush machines? I know in 41TE there is one part that is the most common cause of failure and it's basically a brittle plastic cylinder. There is a metal replacement for it, but I forget what the part was, only that some engineers tore down a lot of these trannies once and found it to be the common cause.

I also find it strange that the PH claim would also apply to normal changes since there is actually more old fluid but probably not enough to dilute the new fluid's detergents or mitigate the PH level.

 

According to the Advance Auto Parts and O'Reilly Auto Parts websites, the hose is 11/32" ID (.344")

 

Thank you. I don't know how you found it (I couldn't) but knowing that, the 3/8" tubing I got should work(3/8=12/32).

With a hose clamp on it, should be fine.

 

You're welcome.

Here's how I found it on the Advance Auto website:
1. I entered your vehicle information as a new vehicle.
2. Did a search for "transmission hose:


3. Clicked on the link for the first item.
4. Found the diameter listed in the item description.
