My t5 has developed a slow leak.
I had the case alum welded about a year ago around the lower drain plug (which hair-line cracked as I was tightening it last year after a fluid change).
The fluid looks like it's coming from everwhere though.
Is there something I can add into it to help with the leak situation until I get it out?
It's starting to whine in mid 4th and 5th gear a little as well. I think my endplay may need to be adjusted.

damn...

 

If your T5 is a Non World Class, I think that you are out of luck for that leak. Your case has stretched enough around the front bearing that you have developed a leak. I have the same issue, NWC T5's don't have a seal around that bearing. It is only a matter of time before it stretches too far and dies. The noise is also an indication that you have torqued the case.

 

No, I have a world class t5. All the bearings and synchros were changed 5000miles ago. I think the rear section of it (where the shims are installed) has to be adjusted.
