0773 code,.....everyone tells me i need a rebuild to repair, i have no notice of issues in driving or shifting, have 215,000 now....cant get an inspection, only a waiver thru the state DPS...Id like to repair the solenoid and flush out the system, some say shops just want the money they know they can get by telling me to rebuild...couple people say it could be a risk that they do the repair and fluid and it goes out completly....i just need a honest answer....and not be in-debt over it
I do not have a solution yet, but I got code P0773. The check engine light has been coming on radomly and sometimes the O/D light comes on blinking for a few minutes. I am trying to find where the lock-up solenoid is and I'm trying to figure out how to test the system to make sure that it is the lock-up solenoid.
P0773 check engine: Shift solenoid E Electrical comes on only when engine is hot Not fixed as yet
Loud Clanking noise when shifting into Drive or Reverse not sure if this is a result of the P0770 code issue.
researching further....any help would be appreciated...
I have a 2000 Toyota Land Cruiser that has less than 75,000 miles on it and am getting a P0770 ODB2 reading with a Check Engine Light illuminated.

The vehicle will not shift into high gear (4th) but otherwise runs fine. What is involved in diagnosing the problem? What is the worst case scenario and what is the best case scenario from a problem and cost to repair stand point?

The Check Engine Light turns on and off. Also the O/D light flashes, remain lit or sometimes turn on and off. Trouble code is P0773, Shift Solenoid E Electrical.
Noticed transmission slipping. Had fluid changed, seem to stop for a few months but is back again. Tripped code this time. Not sure what to do.
Check engine light on giving codes P0135 & P0773. O2 seemed ok by emissions.
I haven't been able to get it fixed yet, but the error codes coming up on the OBD reading were P0770 and P0773.
This problem been on and off for a long time, and accompany with odd shifting issue,
cold car, 2nd to 3rd gear must over 3000 rpm,
And last gear (70 miles at 2600 rpm) mostly won't reach.
I have not fixed this problem. I get P0773 code. When I look up what the code means, I find several possible problems. I have a 1995, Toyota Camry, V6-LE

Below are the three different problems I have found for this code.

- Shift Solenoid three
- Transmission Solenoid Assembly No. 3
- 3-way lock-up Solenoid
Transmission has slight lag when shifting, but all gears work including d2 and L, also reverse. Going to sand ground connection(s) to trans housing/ solenoid first, then troubleshoot the 3way for resistance. Then maybe change it out if rendered faulty
I have the same p0770 o/d light flashing 94 toyota camry 1mz-fe. If you don't a shifting problem like my than here is problem it took me 6 month to figure this one. I reset code for egr problem after I had fix the problem so the computer was monitoring IM status before it completed the gas light came on than follow my mil p0770. To fix the problem fill up the tank make sure you fill it up it might take up to 3 fill up for the IM test to complete. Disconnect the battery wait about 5-10 minutes than reconnect the battery the mil sould go off as long as the gas light doesn't come on than you don't have any more problems since this problem happen I now make sure the my gas doesn't get below half.
Drives fine. No problems other than the check engine light. Light comes on when I reach freeway speeds.
Check engine light started coming on at 113,000 intermittently. Now on all the time. "Shift solenoid E-electrical". Car seems to work fine. It now has 155,000. Have it fixed or get another car? How have others solved this problem?
No symptoms, only a little slow when going uphills. Check engine light turned on, code Po773, car passed all smog test except visual check engine light. Didnt want to deal with this, could be a cheap fix or expensive, decided to retire car.
