1997 Dodge Caravan Cracked Transmission Case

Aluminum welding of anykind is specialized. If JB weld says it works on aluminum and it's not cracked in a real high pressure critical area, I would give it a try. If I told you what I did with JB weld on a turbo shelby charger cylinder wall that lasted a year. Well, I never tried it on aluminum but I do wish you luck. Too bad you don't live near me, I'd give you 500 as is. Good luck with it. The surface preparation is so important if you can find the proper compound.

Did the case crack due to the large pin coming loose in the differential? If so, scrap the case. It's spread apart in an area that was machined to critical tolerances. The pin issue is common.

If the crack is somewhere else, not caused by internal part failure, that's different.
