I have a 94 Caravan (4cyl) which has a slow but steady transmission leak at the point shown in the photo above. It leaks all the time, not just when it is running (I think). The transmission works fine, and the fluid doesn't smell and it is pretty clean looking.


The point where it is leaking is the vertical cover on the end of the bellhousing right where it faces the engine. It is actually coming out of that little raised part in the cover... I wasn't sure if that is some type of weep hole or just a spot where you can put a screwdriver if you needed to pry that cover off. I suspect that it IS a weep hole, and that ATF is not supposed to collect in that area, so that most likely this indicates a bigger problem.


I stuffed some tin foil in there and it slowed the leak; but I would like to know if it indicates a bigger problem. I was also curious what type of automatic transmission that is... it says 424R....and if I should try some stop-leak product in there or if that stuff might do more damage than good.


Thanks so much for your consideration!

 

Welcome to DF

I would need to know if you have a 3 speed or 4 speed transmission behind the 4 cylinder engine. If it a its a 3 speed it would be a 31TH or a 4 speed would be a 41TE transmission.

 

Thanks for your reply. I am pretty sure it's a 3 speed, the 31th, it has Drive, 2, and 1, no option for a 3rd gear. It looks like the pictures of the 31th I have seen all over the internet. It leaks almost a quart a month, maybe 3/4 or a quart. Is it worth putting some stop leak product in there, or does that have the potential to mess anything else up?
Thanks

 

Most likely it is the front pump seal behind the torque converter or there is a slight leak in the pump casing O-ring. The parts are cheap but the labor is high since the tranny has to be removed from the vehicle.
