I have an early LS 400 (1991) fitted with a 3 speed plus overdrive transmission.
A few miles into any trip I get the amber O/D light flashing slowly. The main dealer refuses to tell me what this indicates.
Can anyone out there with a workshop manual advise what this little amber light is trying to tell me please?
Thanks in advance,

I had a 92 ES 300 that had the same problem. Initial diagnostic were the transmision was shot but in the end it was a dirty connection on a sensor socket located on the transmision housing. If I had taken advice from Lexus NZ they would have taken the transmision out and rebuilt it for about $3000.00 A trip to a specialist transmision repair shop fixed the problem in a few seconds at no charge. The vehicle has since been sold and travelled in excess 200,000 km since the incorrect diagnossis was made and only had regular servicing with no further probems. I'm now a happy owner of a 99 model and continue to get it fully serviced every 10,000 km at Hutt Automatics in Lower Hutt.

Thanks Hogie.
I hope the same is true of my transmission. I took the car to the local Lexus dealer who said the 2 nd gear valve was breaking up. Needless to say I didn't believe him because Lexus would take precautions against this. Also I have little confidence in this Garage's abilities to correctly diagnose problems.
I shall do as you did and go to a specialist.
