Hi, this is my first post, but I've got a trans gear oil leak at the gear. I've tried various orings and the one from atkins but none of them seem to seal correctly. any recommendations or advice you guys can give?

I also have an intermittent popping noise that i believe is a bearing due to leaking fluids. It only makes noises when I'm out of gear.

 

O ring is 1011-17-443, suggest you get a Mazda one.
the internal oil seal is 9958-60-8166

 

any idea where I can get one?

 

Any local Mazda dealer or Atkins Rotary (www.atkinsrotary.com).

 

I've tried atkins, it's what I have in there right now and it appears to not work. When I put it in it seemed to be the right size but everytime I go under the car there's a little drop. It's not the rear seal, that's bone dry. I'll try my local dealership.

 

Hairline crack? Residual that pooled up? Can try an O-ring lubricant/grease like molykote. Something that will slightly swell the o ring. The shaft and cable section is usually leaking on most of them. Best of luck to you

 

The old one cracked when i pulled my trans for a seal refresh and the atkins one visually is good, I always wipe it when I mess with it and after a drive there's a drip. I'll look into a swelling thing but doesn't it swell after heating up? heat, expansion...
