Shops usually charge on an estimate of time regardless if it took shorter or longer time than book states it should. I would imagine this is a $800-$1500 job. I could be totally off though.
When he looked it up he said that the book stated 3-3.5 hours I think.

General parts list of transmission valve body

It does appear these solenoids cost more than I thought... just ran some of the PNs for pricing and they are in the $150-$250 range each

Maybe then $1K or so for parts and $500 for labor? It could push closer to $2K as well and then any associated taxes.

Default 2011 check engine hlow flashing help

2011 gx460 - 126000 km .
Guys i need help,
since the confinement I have not driven my car very much . Here is the problem explained:
when i come to drive and shift to D , N or R it feels “ buttery” like very smoth to smoth. when i bring the shifter **** to D position I realized the red light did not come up beside it to say it is on D position.Then i drove a little and the dash lights up with the four light flashing.( hlow check engine ,...)
Now the transmission feels the same as usual no issues at all i know my car very well.
30 min into driving and stopping everything dissapeared and shifting is back to normal when moving to D position the light beside the D is red again. Any help would be very usefull.

Do you have a code reader? It could be a failing component in secondary air system.

FYI: Unless codes were reset the code should still be around as a historical one even if CEL is now turned off.

Unfortunately ..if there were historical could you would likely need Techstream, OBD Link/Fusion, or possibly BlueDriver? There are other diagnostic solutions but they are $$$

I believe the code indicates a failing neutral safety switch module. Double check your battery and alternator are good. Auto Zone or Pep Boys will do this for free. Failing power can cause weird issues if it is the case.
