Not everyone can rebuild an automatic transmission. They may, if they are lucky, able to change the oil and maybe adjust a band it thats an option, but, to pull all the bolts out to remove it, pull the front pump ass and replace the clutch plates and seals?Strange analogy.
I've never owned a vehicle with automatic transmission, so my opportunities to dismantle, let alone rebuild, one have been severely restricted (my choice).
However, I am aware of the existence of professionals who will, for a financial consideration, perform the required operations for me.
There are also others who will, if I show willing and/or another financial consideration, teach me how to perform the required operations for myself.
(My silence on this thread so far has been due to ignorance of the existence of the thread, until it was reported)
