Hello,
I have a small tranny fluid leak at the speedo gear housing. Probably 2 tablespoons while sitting for a week or more.
According to the manual, it is either the speedometer gear housing attaching screw or the speedo drive gear oring
I have headers, so I think I will need to remove the drivers side

Any words of wisdom on what to expect once I get in there?

Thanks, Scott..

No need to remove headers, undo the reducer and there is a steel bracket
with a bolt that attaches to the trans, remove it and pull the assembly. We
supply the rebuilt one with new seal and swap.

Jim K,
I have the speedo that is corrected for the 3:21 final drive. Do you have the rebuilt one for that?
Scott.

You will reuse the plastic gear and we supply the Bullet with a new seal. I
believe we show that on our sight.

Kicking myself in the butt for not doing this sooner.......I have actually lost sleep over this...
Also kicking myself for going over the specified torque torque value.....
