I was driving on the highway last night, only driving 60 mph. And I noticed that my rpm was at 3000 and wasnt shifting down. Is that normal for a 94 lexus es300 or should I get the tranny serviced ??? Any suggestion would be appreciated. Thanks

was the engine up to operating temp, the ecu will not allow a shift to o/d til the engine is warmed up...

Yes it was to operating temp, i was just wondering why it wouldnt shift back to 2 or 2 1/2 rpm after driving at 60 for awhile

capnfred

was this a one time event, or does it persist,,,,,,

At 60 mph you should have been at around 2250 rpm.

Sounds like your OD did not even kick in.

@ Capnfred - It happens everytime im on the highway. I was thinking about flushing the tranny or getting it serviced

@ PFB - I usually drive with my OD off, do you think that the problem is that I should drive with the OD on??

I always have the OD on that way you will be in Overdrive and lower the RPM

Do you mean that it (no 3rd-OD upshift) happens ONLY when you're on the highway?

Drive with the O/D on or it will not upshift.

It could be time for a tranny fluid flush along with the filter. If you want to DIY, it's not that hard. The filter costs about $30+.

Thanks to everyone who helped me solve my problem, I had to turn on the O/D and it shifted to 2250 while during 60 yesterday. Now i'm having a problem with the O/D light flashing every time I turn it on. If anyone can tell me whats going on I will appreciate it ?
