Converter Drain Back

[Babaganoosh]

Does it leak right away after resealing everything or only after one of your Offroad sessions?

Both but 1 moab trip and it sits like this. I do a prep before which always reseals it then after. Although I have not touched it sense last year.

I do have a new transmission crossmember coming. It uses the same stock poly mount and I have poly leaf spring bushings for engine mounts. I do think frame flex is destroying it, but with right stuff I have to pry the tcase off.

I see you don’t have the brace rod in that pic. Do you not have it?

I do, I have had it on and off and it hasn’t made any difference. Next time around I’m going to install it anyway.

My Jeep drains the converter into the pan after a few days. I placed a one- way valve in the line from the trans to the converter and fixed that.

The K5 would loose fluid from the transmission tailcone into the xfer case. Occasionally had to remove the xfer fill plug and let it drain down then add to the trans. Had the tailcone and xfer case seals replaced and fixed that. Now it just leaks around the case. When it stops leaking is when I get worried.

Can you provide more information on this? I believe the checkball in the turbine shaft is only for controlling the lockup rate, not to keep fluid in the converter.

Its a simple in line valve that is\was installed on some mopars between the cooler and trans output. Drain back appears to be a pretty common issue as there are several sites for different vehicle manufacturers discussing this problem with several pointing to converter or valve body seals.
One thing I don't like about the valve is it reduces the diameter of the line in that spot and I can't verify flow restrictions.
Its basically a band-aid.

On the cooler makes sense. I was trying to picture how you would do this with the converter.
