KC98LS

I let my 1998 LS400 warm up for a couple of minutes today.


I got in the car, put it in reverse and backed up about 20 feet. I then came to a complete stop, and placed it into drive. To my surprise the car wouldn't budge, it was like it was in neutral, but it sounded different. Thought I had left my parking brake on.


I turned the car off, placed into park, and applied the parking brake.


I checked the transmission fluid, and it looks great, was changed under 10,000 miles ago. Level is fine.

I started it back on, put it into gear, and it was like nothing ever happened.

Car currently has 188,000 miles and counting.





Is this something I should be concerned about, or is it just a random glitch? I've never had it happen before, and the transmission has given me zero issues. Of interest, my battery is getting weak, and I'm planning on replacing it soon.



Attached is a Dropbox video documenting the issue.






Thanks!

Ended up going out to the car tonight.


Scanned for DTCs, and found absolutely none. Here's the report.

Try charging the battery, weak LS400 batteries can cause all sorts of issues.... although not going into D would be a new one to me

It's good that there is no tranny code but that doesn't mean you're home free. Many internal trans failures will not throw a code. You can try checking the trans shift linkage and position selector switch to see if they're within specs.

wow KC, you took all the bullets out of my gun... I really dont know what to say.. linkage dose not sound right for the way it happened... it seems like anything electric would show a code..

try unplugging the battery for 15 min and see if anything changes. Worth a try, right?

Haven't had the issue since. Restarted engine and everything was fine. Replaced battery with brand new one.
