transmission lock mechanism is abnormal after TRANSAXLE CHANGE

i only need it for this repair and i basicaly just want something that can erase my codes and check to see if they still come up after the repair... i have an actron cp9180 but it cant read those codes... and probably cant erase them eighter. so 170 for the actronix plus 55 for 2 days is ok for me. but 1400 is a bit much

 

that transaxle in the pics is the one i pulled out and, as i said eralier, it fell to the groung , landed on the actuator, and broke the three legs of the suport that the actuator bolts on to. that suport is part of the cycloidal reduction gear so i could not use the electric motors rotor to turn the parking shift rod. i turned the rod directly and it only turns one tenth (that's 1/10) of a turn ccw - counter clockwise to engage the parking pawl or cw -clockwise to disengage it. next week i'l try it on the prius to disengage the parking pawl and i'l do it using the actuator's motor rotor and i'l let u know about the number of turns it requires. btw: anybody knows where i can get a shift control actuator for the prius? there are non on ebay and dealership wants 640 for one. for 500 i can get another complete transaxle of ebay shiping included...

 

ok folks. i finally had a few hoers to mess with the prius. had to get the suspension cross member out to have access to the parking pawl control actuator aka shift control actuator.first the front wheels have to come off. then it took me about a hour since there are only 18 screws holding the thing. the photo shows the order in which i toke the screws out:
7 and 8 are for the steering rod from under the steering wheel next to the brake and gas padels.
before geting the 15, 16, 17 and 18 out you want to put a big kack under the suspension cross member so it wont fall to the ground...

 

then i got the plug off and then the screws and gentelly pulled it off the transaxle...

 

now for the "creating new knowledge" part. to engage or disengage the parking pawl: if the rotor came out with the shift control actuator, one has to put it back in the cycloidal reduction mechanism. when putting it back you have to pay attention to put the rotor all the way in flat against the rest of the mechanism. chances are it wont go all the way in and flat first time you put it in. so just take it out a bit, turn it about 1/10 - one tenth of a turn and put it in again. do this until the rotor gos in all the way and the rotors teathed gear is flat against the mechanism.
now one can turn the rotor to engage or disengage the parking pawl. to disengage the pawl you turn it ccw counter clock wise about 3 turns. you will hear a click once it disengages. to engage the reverse: turn it clock wise about 3 turns until you hear the click.
2 interesting things i noticed:
1: turning the rotor has a nice spring feel to it in that if you turn it just one turn and let go it will rotate back like letting go of a spring.
and 2: the cycloidal reduction mechanism changes the rotation direction. turning the rotor about 3 turns ccw - counter clock wise will turn the reduction gear output clock wise - cw about 1/10 - one tenth of a turn disengageing the parking pawl.

 

after disengaging the parking pawlm putting the actuator back removeing the p con main fuse to reset the c2300 code, i tried again to start the car but again the abnormal lock mechanism message... so i was curious to see if the prius even tries to turn the cycloidla reduction mechanism. so i took it all off, put it back together separated from the transaxle, marked the output with a marker, plugd it back in, again removed the p con main fuse for 60 sec to reset c2300 , and pushed the start button. again the abnormal message. chacked the markings on the cycloidal reduction mechanism output: nothing happend, it didn't move atall.

 

i tried to inspect the integration relay but it's missing a pin compared to the book. the book says to test the resistance between a4 and c1 and b4 and c1 but there's no c1 on the relay. how can i test it? where's the c1?

 

removing the relay is easy. one just has to use a small flat screwdriver to push the retaining ears away and push it up. than just unplug the cables from it. my tactrix cable should arive tomorrow. will post everything i find...

 

ok people. i'm shure everybody was worried: what happend to platypus81 ? did the prius fall on him while he was working on it?... No,no ,no... everything is allright.. i just didnt have time and you'l see in a sec why. finaly i got the prius running. and yes , it was the shift control actuator. the problem was that i got the replacement transaxele with a smashed up actuator. i notified the seller and he sent me another one but thanks to toyota's infinite wisdom it seams that parts that have the exact same part number on them are different in more than one way, and so the second actuator had a small plastic stud that i missed while installing the actuator and that causedone of the actuators legs to brake. than i notified the seller again but this time he made me pay for another actuator 150$.
o week later i got the actuator but now the actuator would not fit the mounting on the transaxle. it seams that each actuator gos with his mounting. if you mix them you can get a pair that don't go together. so again, i contacted the seller and he told me to ship all the actuators and the actuator mount back to him.

 

so i shiped everything back to him only to get a actuator - mount assembly that had a twisted rottor with a missing part. luckely i still had the old rotor from the old transaxle. this rotor was sitting on concrete in rain for about 2 months. i cleaned it a bid. put it in. and boom, the prius started.

and that's all folks. i just wanna say that if anyone needs the shift control actuator changed, if you wanna be on the safe side than get the actuator-mount assembly together.
