I got a pfinh code my tranny is fine change oil to the tranny and engine .... car starts but will not move at all

 

what FLUID exactly did you use for trans fluid??? honda atf?
how much -3 qts?
by what method was the fluid changed- drain and refill
this is important to the trans!! the wrong fluid will destroy these trans fast

did a shop do a machine powered trans flush and new spark plugs for you?
If so make sure it got the correct NGK Iridium (upgrade) or NGK Platinum (came with stock) spark plugs it requires
they are about 8-10 dollars each,,not 2 dollars each

quickie shops will throw some bosch or other non approved plug in--a few miles later they crap out and multi cyl misfire with poor running occurs

someone recently posted pics of bosch 4plugs after only 5000 miles in a TL- loaded and carbon coated--not good~

 

is this a usa north america car?
I have never seen a code like that reported here,,
usully something like P4021, as example

 

That sounds as if you didn't put transm. fluid back in = no movement.

 

or power flushed and filled it with dex3
or knocked a wire loose for a selenoid under the car
or one of them happened to fail at same time

there was a member with immediate no shift- stuck on the rack at trans shop, turned out to be a selenoid
iirc
if this old mind recalls
