Default 1993 Lexus sc300 cruising rpms & gear radio ?

Hey club lex, have a question that I can't seem too find information on. I'm having a problem with my sc when I'm on the freeway lets say I'm only going 60 mph and I'm just about 3k-3500 on the rpm.

It's revs high in my prospective ? Is it Normal ? Can anyone answer this ?

It still has the stock 4 speed with overdrive.

Also what should it be at

Thanks peeps for the imput !

count all the gears your car may not be going into 4th gear because i had the same problem and thats about where you would be in 3rd gear. 4th gear is 1.9k rpm to 2.1k rpm so see if you can count the gears or do a little vid of cruising on a straight away i changed my ecu and problem was solved it happens to are ecu's with age

Thanks for the reply homie, I was messing with the ect and the overdrive it's self and it does kick in too 4 gear driving on the road. The freeway is were the problem seems to happen
I want to cruise farther then Orange County but the fact that it revs so high concerns me.
I drive about 14 miles back and forth when I go to work so that's when I tingle with it
