I can't find your diagram on this tread, only Cam69SS'. Can't find any diagram related to the valvebody under "Thomas1" either. Do you have a link? Thanks.

Default Spring Diagram

Here is the diagram of the springs from my '01 ES300 service manual and their location with colors. Hope this helps...I think the transmissions are the same...

Part number 35230 is your Shift Solenoid D. I have the book for rebuilding this transmission. You can also go to Youtube and type in lexus RX300 transmission rebuild and you will see about 14 videos.

Just want to thank you in advance for any help / advise you can recommend re: P0768 shift solenoid D electrical. We have 1999 FWD RX300 with 192K. I'm not sure if there are any relations to CEL above, but prior to getting code. The driver side under dash was making a irratic ticking/clicking sound like electrical relay. Now when I put it gear it feels like lunge and not the normal smooth feel. I haven't really driven the car out of garage yet for fear getting stuck.
