Transmission pan problem
Some of the bolt holes on my trans where the pan bolts to have become stripped out. There are 4 bolts in total not even there. I was thinking I could tap them to a bigger size and put larger bolts in there. What size should I go to? Or is there a better solution? I need to get this done this weekend. Its leaking fluid from the gasket. Also will be a good time to install my superduty transmission pan.

The pan bolt size should be either M8x1.25 or M6x1. You should be able to go to your local parts store and get a helicoil kit. It will come with directions and tell you what size drill you will need. Absolutely do not use sheet metal screws.

Well I got some helicoils, m6x1 tonight and got the all the stripping pan bolt back in. Those things are amazing, wish I had known about the longer. But I still have a few drips coming from the gasket. Im starting to think thats my problem. Im using the rubber reusable one with my 4r100 pan. Anyone else have issues with it. I never had leaks in the past with the old style.

Make sure that the heli coils are in all of the way. If they are sticking out a little bit, they will not allow the gasket to seal all of the way. The end of the heli coil should be at least one thread beyond flush.
