Q: Vehicle not shifting into higher gears

Hello, with any transmission issue, the first thing to inspect is the transmission fluid level. If the fluid level is low, add the correct amount and drive it again to see if it shifts. If the fluid level is good, and you are still having shifting problems, the car should be scanned for code to see if there are any present for the transmission. If there are no codes present, then there are flow charts that must be followed to find the cause for the no shifting concern. In these flow charts there is also electrical testing that must be performed since it's electronically controlled. There is a chance you could have filed wiring or a solenoid in the transmission. For an issue like this, I recommend having a qualified mechanic come and inspect your transmission to determine why it is having trouble shifting into higher gears.
