Not sure if thread is still alive again 2000 rx 300 not shifting into overdrive no engine codes or lights are popping. I just cleaned my Maf still no 4th gear and no codes… my girl was driving the car and when I checked oil and violent were damn near tapped out filled cooper and did an oil change while I was cleaning maf so nothing changed did a hard reset and pulled the battery for 30 mins to see if it would give me some love but still no 4th gear/overdrive my next step is the over drive sensor (because it would tube the cheap fix) but if anyone has found something that might be faster and or cheaper to look at people love any info
