Hello all, while changing my transmission pan and filter I went ahead and put a A518 Mopar Performance cast aluminum pan in place of the old one. The bolt pattern matched up fine with my 46re, and I attached the filter extender to the valve body. But I still have two questions.

What should be done with the pan magnet? Since the pan is cast aluminum, the stock magnet will not stay attached. The drain plug provided with the aluminum pan is not magnetic either, and I'm not sure that a magnetic drain plug would trap enough of the magnetic silt that clogs solenoids and valve bodies.

I am going to reattach my old bypass fluid filter to the frame as well, and I believe the best place to put the one I have would be inside the frame and close to the return side of the 46re. To do so, though, I will have to cut the return line, which has already been cut to allow for fitment to an external cooler.

Would there be any disadvantage to running flexible hose for the entire length of the return circuit, e.g. from the oil cooler to the filter and then into a new barb fitting at the transmission?

I plan to spend the weekend thinking about and researching this (and working on my girlfriend's car) before tackling it again early next week but I am already thinking of dropping the pan again if necessary for no other reason to put in the GM conversion solenoid, and am grateful for that tip.

Thanks!

 

There have been several threads on this forum that discuss the installation of an external transmission filter using the return line, especially to get rid of the in-line check valve that tends to clog and cause premature transmission failures. No issue in tapping into that line - just if you need to extend the line, be sure to use hose rated for use with transmission fluid.


As for the pan magnet, might want to consider magnetizing the drain plug that you have. You can also epoxy magnets to the pan too, if desired.

 

The check valve was deleted as part of the last rebuild, and I do like the idea of epoxying a magnet to the pan bottom. Although I suspected it, it's good to know that the return line can be clipped back a little further if not entirely replaced.

As well, I may try to magnetize the external filter itself for peace of mind, either by stacking a couple of round magnets inside or lining bar magnets around the outside.

Thanks!

Just be careful where you place the magnets on the pan - you want to ensure that they do not have any clearance issues when re-installing the pan (for example, not rubbing against the valve body, etc.).

here is an EXTERNAL filter. i do have one on my dak.
man o man i about forgot yes its a cut & past sorry. __________________
after you clean the trans. add this to your*chrysler*trans. an external fluid filter
1. go to auto-zone. get 2210, its called a power steering filter, but it is for transs to. it is for 3/8 tubing. by (magna-fine) be sure to use high pressure hose. Reff:http://www.magnafilter.com
2. for other sizes wix 58964 5/16 tube size
