Hi: Need your help...
I have the same P0773 issue...
My car is 1999 Camry 4 Cyl 5A-FE engine.
What i am most interested is the TSB for the identification of the solenoids.
The TSB from the NHTSB site is dated Aug 2005, Bulletin #01005
summary states; A541E Transmission solenoid identification ( NHTSA item number 10016637)
Do you have this TSB ?
Thanks
Padaki
