Thank you for the kind words. I am sorry to hear about yours, you can't choose family unfortunately. I was very lucky with my Father.
That is correct, he did work on cars that lasted 200k. I have kept cars alive as far as 289k with my own hands, where I fail is transmissions.
I just did not learn enough about them Thus, I am asking you. So thank you for the knowledge.
I did not know about the frequency of fluid changes for Subaru's. I had it changed at 100k, as I would expect it to be changed. Good to know, Thank you. The cost of getting a new transmission is ridiculous. So I have to weigh my options carefully.
I found one 23K, legacy trans. But the Trans codes don't match. So I am not sure what to do here.
I have been told the valve differences and all electronic bells and whistles may make it difficult to get it to work.
Thank you again!
@m sprank I learned what I did by watching, asking and doing...yet I claim no expertise. You are the experts, that is why I am here. Please forgive any agitation that I may cause, I mean nor have any hubris in the matter.
But as a side note, you actually mean "diffusion", "osmosis" most commonly refers to concentration gradient in water.
This I know about, I am professional Chemist....LOL. Thank you for your help.
