I would check codes first. Newer transmissions take a bit of diagnostics. Could be you need a rebuild, could be just a TCM or upgrade. Price is from, upgrade, a couple hundred, Tcm, 800+, rebuild, 2000+.
The first thing I'd check is the level of the transmission fluid. Make sure the vehicle is level, and is up to normal operating temperature. Check It while it is running. If it's low, there's your problem. If it's okay, then you may need to change the transmission fluid and filter. The transmission filter is similar to a filter on an A/C unit. Like a screen to catch the junk in the fluid. It's located inside the transmission pan on the bottom of the vehicle. If you do it yourself, make sure you use the right type of transmission fluid. Filters and fluid are relatively inexpensive to replace.
With all of that being said, all of that information was for an automatic transmission. Not for a standard transmission. If your transmission fluid level is okay, and doesn't need changing. Take heart, that doesn't mean you're looking at a complete transmission replacement either.

The blinking overdrive button is telling u that a serious fault has occurred in the electronic controls or a mechanical fault such as excess slippage is occurring.

Check both O2 sensor(s) and catalytic coverter.. P0420 means catalyst below threshold. Also check the sensor at the transmission and solenoid.
