Posted this in the q and a section and apparently nobody knows anything about Dodge automatics, so, I'll give it a go here:


It's a 46re in an '01 Ram that developed a louder-than-usual whine in 1st, 2nd, and 3rd. The pitch changes on gearshifts. 4th gear seems fine, no noticible noise.

Fluid is darker than normal but still has it's reddish color.

Doesn't do it when the truck is cold.

This just started a couple of days ago. At highway speeds everything is fine and the truck pulls great with no slippage.

If I'm not mistaken, this trans is based off the 727 so hopefully you guys have run into this before.

The only thing out of the ordinary is I'm using an electric fan so there would be zero airflow across the trans cooler with the fan left off which is 95% of the time.

Any suggestions?
