I added transmission fluid to the power steering pump

What brand and spec was the tranny fluid? ATF+4 is the only stuff to use for a Ram Truck/Van. There are modifiers in the fluid too. So, it could make things stiffer. Also, the ATF+4 is synthetic, thus the molecules are a larger constant size vs. the DOT fluid rating range that should be used.

I found this info already posted in this forum.
TSB from Dodge:
ATF+4 is compatible with other Chrysler approved power steering fluids, but to avoid confusion due the fluid color difference, ATF+4 should not be mixed or used as a "topping off" fluid on systems requiring MS5931 or MS9933(these are dodge approved PS fluids). On some past models, ATF+4 should be used as the replacement fluid. On these models, if a steering system is being serviced that results in a large fluid loss, such as a pump, hose or gear/rack replacement, the complete system should be drained and filled with ATF+4 (MS9602).
You shouldn't Mix them but you can use one or the other with ATF+4 providing superior results as Dodge claims. it's a TSB because many topp-off people have had issue's with the fluids as they don't comine with one another and if you need to topp off, then you've got a problem somwehre, whether it's an external leak or an internal seal leak? It's a closed system and shouldn't ever need additional fluid.
