School me on wat you think is good transmission maintance?? Automatic 2004 f350 dually

 

Let the dealer do a flush and fill service. After 50-60k drain the pan, replace the small in-line filter, and refill the fluids. Swap back and forth between the two types of service at the 50-60k interval.

 

I did both filters at 30000.The main filter and pan looked fine but the in line was totally black I'm going to change my inline again at 40000 to see what it looks like.. I myself don't agree with the flush and fill method but i like to see whats going on down there whenever i get the chance

 

What is the best Trans fluid to use?

 

u need mercon SP or lv

the pan doesn't have a filter it is a screen only and can be cleaned , the pan gasket is reusable

the dealer hot flush is the best because it gets all the fluid ( these transmissions limit flow through the cooler lines until hot )
second best is drop the or drain the pan a few times over a few days and change the remote filter

 

when i dropped my pan it sure looked like a filter that i pulled out of the tranny. If that was just a screen then it was a fancy looking filter screen
