Bell housing hole

Recommended Posts

I pull the transmission out of an engine which is been sitting for 25 years and i found at the bottom a hole in the bell housing surrounded by white powder, my best opinion is that the aluminum rot and is just disintegrating. Im cleaning as much of the transmission as i can but i dont really know of any good product to use so i going a little slow.

Is the hole is going to have any negative impact?

How can i fix it as to prevent the spread and maybe cover it?

I'd use it if I couldn't find a replacement. One could also TIG weld the damage. I seem to remember Cliff @siteunseen using cheap oven cleaner on a trans, at one time, and reporting it worked very well.

I bought the oven cleaner and is like magic, as for the weld f its not going to affect anything i might just clean it and leave it.

Yes I did use the cheap walmart oven cleaner then went to hot water spray car wash. You can buy these rubber caps in the plumbing section at Lowe's for just a few dollars. Worked out good for me.

Thanks, im new to the transmission stuff and this might go out of the original question but i don't want to create a new post, how do i check the gears?. I know i have to rotate the input shaft but, how do i get them to change when the transmission is like that?

You need a shift lever.

The corrosion around the drain hole is not a big deal.  Maybe some road salt got in there and caused corrosion over the years.  It shouldn't get bigger once you clean things up.
