660catman 13 Posted July 19, 2023 Working on a 99 450ES. When I first got it the electric shift did not work. I sprayed WD40 in the buttons and let it sit for a day. It worked for a couple of weeks showing all gears on screen. Now it does not work at all. Shifting manually now shows when in R, 1 and 5 on the display. It will manually shift into all the gears but 2,3, and 4 show - - - on the screen. Any ideas what it may be? Share this post Link to post Share on other sites
AKATV 823 Posted July 19, 2023 First of all, are you going by the service manual? If you do not have one- here is the link for it https://drive.google.com/drive/folders/15eWwngQ5SdlsIfbgpm5ZJWJYBYx3vJ7s (We have a great FREE service manual library here on the forum) It has a comprehensive ES troubleshooting guide starting on section 21-3 for your year (98-01) I dont THINK the buttons are your issue, sounds more like angle sensor or gear position switch but lets start in the manual and see where we get 1 Share this post Link to post Share on other sites
660catman 13 Posted July 19, 2023 As my wife would tell me, open your big cow eyes! I do have the printed copy of the service manual. One should have looked into it a little deeper first. I won’t have time until beginning of August as I’m leaving on vacation in a couple of days. Thanks for the “kick” to look in the service manual. If I have testing issues I’ll be sure to post more questions. 1 Share this post Link to post Share on other sites
