Was going to change the manual transmission fluid today. But realized that I can not remove the filling and draining bolt as they are not standard socket size.
They are actually hex bolts.

Anyone know what size hex bolt I need?

 

10 mm

 

yup 10mm.

service manuals don't state it and any of the Z service depts won't tell you b/c they want the car in their shop-amazing.

 

thanks,

looks like I will pay Sears a visit next week and pick up some craftsman hex bits.

 

In addition,

Where can I get washers for the transmission hex bolt?

 

washers are about $1.50 at the dealer. Torque on plug is 25ft/lbs if I recall correctly.

 

thanks, my local dealer doesn't have it. They said over the phone that they will have to order it. Anyone know what the part # is?
