What kind of auto trans fluid in 93 mazda protege

This would be a good time to check your transmission fluid level.

check all fluids, p/s,& trans ....this sound sometimes is ***. with the trans (worse case ) or is ***. with the wheel bearings but normally is a rough grinding whining sound

if auto small dip stick on trans case if standard you can not fill unless lifted and check bolt/plug is removed

its a cylinder misfire and trans circuit problem--sensors cud be worn or hav connection issue--has plug wires been changed-also coil me be faulty--has trans been serviced with new fluid and filter-shifting soleniods cud be sluggish from dirt

Have your checked your trans fluid?

this car uses type F ford transmission fluid, why? becuase the trans is made by ford for maxda.

It is most likely burning up. Or there isn't enough in the system or doesn't work its way through immediately

is it shifting into overdrive?, auto or standard trans, at 60mph most vehicles with overdrive are at about 1800 to 2200 rpms...

has someone lowered your final drive axle gear ratio...?

check to make sure the transmission has not come loose. it sounds bad, but i had a simaler problem with a eagle talon. the trans bolts came loose and the trans seperated from the block

I'm seeing a lot of 1994 Mazda Protege problems so if you do replace it I would recommend a new trans and not a rebuilt or junk yard trans.
Most car repair shops use Jasper Transmissions most likely because they build them better than the original!
