Default Pulled two codes

the check engine light on my car has constantly been turning on and off because of these two codes so im finally gonna try and do something about it. Does Anyone have any experience with the PO763 (solenoid circuit) and the PO715 (Clutch speed sensor) codes. I've tried searching the forum but everything leads to a dead end. I would appreciate any help or suggestions.

Hey toy4life, how much did it cost to change those solenoids?

Or did you DIY?

I gotta do the SAME thing soon. I was quoted between $6-700 by AAMCO.

you know at the time i just payed what i had to i think i ended up spending like 1000 because I had to have it opened twice
Its best to do all 3 i guess because they usually are all bad or about to fail so after i got my first 2 done than the 3rd failed also so first time it was like 600 then 400 with labor toyota tranny fluid etc.
I think it can be DIY Jeffsthai or whatnot was supposed to post up pictures but i dont think he ever did. I wish i learned how to do it i dont think it should be that hard though.
I also payed regular dealer price at the time because I had the mechanic open it first and figure out which ones were bad but i guess it woulda been cheaper to buy all 3 and got em all done.
6-7 seems about right check with sewell or trademotion pinebrooke pine lexus for parts
I had a question for you seeing you have a gs4, do you have a srt intake?

Thanks toy4life. I will def let this thread know when I get my solenoids fixed.

I will take your advice and buy all three and just do all at once.
Thanks for the heads up.


I wish I had an SRT intake. It is on my list but its kinda far down cause I have at least 2k of work that has to be done.

Why do you ask?

Had the same P0763. Replaced the shift solenoid. The thread below discusses how to do it. If you are comfortable dropping the pan, it is a relatively easy DIY. Part from Sewell Lexus was about $250 delivered. GL
