E92 M3 stripped transmission strainer threads...

[Dave J]

I changed the oil in my 6-speed transmission. After I drained the oil, I removed the oil strainer to replace it with a new one. When I put the new strainer in, I hand tightened it and used a torque wrench to complete the job.

After another 1/2 turn, I noticed the strainer wasn't tightening. At this point I knew something was wrong. I removed the strainer and the threads of the transmission case were stripped.

The strainer will snug down, but I'm not confident it's going to stay in place.

I've searched for a fix for oil strainer thread repair, but have only found fill and drain plug solutions.

Do you know of a helicoil thread repair kit or some other solution to fix those threads in the case? If you do, please let me know.

TIA

I think a time sert might be best.

If you could find out the thread pitch you can see if time sert has a kit for it.

Anyone know the threads on the oil strainer???
