Obd1 sc300 na-t about 300rwhp 10psi right now.
I was driving the other night normal on the highway crusing about 75mph in overdrive prob 3000 rpms and all of a sudden jumps up to around 4500rpms ...
Overdrive isn't working can't find a fuse for it..
Some people are saying try a new ecu? No CEL ,some people say a solenoid in trans?
If anyone has had similar experience help a brother out,thanks-chad

If anyone loses there overdrive, try a new ecu first.
Bought a Eco off eBay for $85 shipped installed it and I now have overdrive again.

I am having the same issue I don't have O/D
My Lexus is a 1993 sc300 and I removed the ECU and found it had already been rebuilt prior previous owner. I took the car to buddy shop because he has a lexus sc300 1992 and swapped computers and car would not start with his computer. I will test the speed sensor and see if that could be causing the problem, but I will get to the bottom of this issue.
