Driving first thing in the morning, every thing OK. After the engine warms up and either I stop or slow down to where the transmission has to change gears, the transmission will not shift into 4th gear. After it has set awhile, engine off (+/- 15 minutes) the car will shift OK until it has to shift through all the gears again. Same scenario)???
Cause? transmission will not shift into 4th gear after engine warms up on 2001 Lexus RX300
