Transmission cooler questions

[Mosinguy]

I'm about to get a 92 Ranger with the "dreaded" A4LD. I know the guy very well and he's the original owner so I know it has been taken care of but I want to prevent any future issues. I'm going to pull the transmission cooler from my friend's old E350 Diesel. I think that'll be a big enough cooler.

However, I'm not sure if I should use an inline filter, how/where to install the cooler, and if I could use an electric fan. Do I want to hook my new cooler down the line from the stock cooler, or should I just bypass the stock cooler altogether? Also if I install the cooler in front of the radiator would I run into any issues with airflow or overheating? Lastly, I know I should put the inline filter down the line from both of the coolers but would I really benefit from the extra filter?

P.S. If I run my A/C at full blast I know the condenser will get super hot. Will that affect my trans cooler enough for concern?

I would run the trans coolers in tandem, and keep the new tranny cooler in front, as low as possible. It shouldn't need an extra fan or an in-line filter. The biggest use for in-line filters is after a major trans failure when you aren't sure that you were able to clear all the debris out of the coolers. They keep that stuff from getting back to the new transmission and destroying it.
