transmission stays in overdrive on 2007 Suzuki Reno

When vehicle is put into gear does not respond. Turning off the vehicle several times will get it to respond into gear.Feels like it staying in first at times. Check engine,passenger air bag light are on.

you need a trans shop for a diag. there could be a lot of resons for this and a lot of them external not requiring removal of the unit.
a shop with a scan tool is your answer.
