Automatic gears wont go into gear

SOURCE: automatic transmission is stuck in 2nd gear (limp mode)

most newer vehicles  have transmission control modules,that go to a default of 2nd or 3rd gear when they go bad!  I had a 91 plymouth stuck in 3rd gear because of this module! could be your problem!    when mine went out, it smelled like something electrical burned inside the the passenger cabin! I would check all the electrical connections on the transmission first    good luck

SOURCE: toyota surf automatic it wont change gear ?

I assume you are saying it is late to shift. There is what is called a Throttle Valve ( TV) cable that goes from the engine to the transmission. If this cable is out of adjustment, or too tight, it will cause this problem. While you are at it check for vaccuum leaks on the hose from the engine to the tranmission. A problem here will cause a harsh shift, but necessarryly late shift

Good Luck

What do you mean "rooted" ?
Generally if a manual transmission is stuck in gear it points to one or several of 6 possibilities ( barring any damage to hard parts such as gears or shafts.)
1: Damaged shift linkage.
2: Worn clutch.
3: Faulty clutch slave cylinder.
4: Damaged fork assembly.
5: Damaged synchronizers.
6: Bad throwout bearing.

Be prepared for sticker shock when pricing repairs or parts !
Mazdas are not cheap to buy parts for or to work on.
( thats why I will never own one )
