I know that my fifth gear syncro is not in good shape. It grinds sometimes going into fifth. But, I was wondering where or who can tell me what it is that goes bad and where to get the parts.
Please Help. I am going to do the rebuild my self. I have a friend who rebuilds automatics and manuals at a GM dealership.

 

I have a bad 5th gear synchro also and it is going to be fix by Dave at KDR. From what I know it is only the sychro that is bad and the parts is real cheap. It is like a ring with teeth around it, and I saw one that is breaking in two parts. You should be able to get it from a reputable Mazda that sells oem parts. Now if you doing the labor yourself it is cheap compare to have someone do and charge you labor. For me I have to pay for the parts and labor total comes out to about $479.

My extension housing is leaking tranny fluid very slowly due to the fact that Mazda had replaced the syncro on my car before I owned it and did a lousy job. Is there enough clearence to lower the tranny, still attached to the engine, and remove the extension housing and replace its gasket?

 

This is it. Go here and look at my post it is the part that is broken

If you going to change the 5° gear synchro, change the shift select spindle is very easy once the gearbox is down.

take a look in www.scuderiaciriani.com.

the spindle is about $40 or $45 and the synchro is around $25.

i have the upgraded shift select spindle, there is a big diference when you change gears.


good look.
