TRANSMISSION WILL NOT SHIFT INTO OVERDRIVE

2002 Lexus SC 430 • 48,000 miles

I have a 2002 Lexus SC430 with 48,000 original miles and the transmission will not shift into overdrive while driving. I checked transmission fluid---it is full and a red color No warning lights on dash I had the computer ran and no codes came up It has been doing this for about 2 weeks Any suggestions?

Thank You for any help!

Also does the transmission have to be dropped to replace the valve body or can it be done by removing the transmission pan and filter and installed that way?

It can be done underneath, $1500-$2000 for a valve body don't sound right-too high
