I'm tooling up for axle and trans fluid changes on my '06 Explorer V8 this weekend.
Here's what I have so far:
6R60 Trans : Motorcraft Mercon SP, trans filter, gasket.
Front Differential : Valvoline High Performance 80W-90 (Has 'limited slip' label on it)
Transfer Case : Motorcraft XL-12 Transfer Case Fluid
Rear Differential : Supertech 75w140 Synthetic
I'm wondering if the lubes I chose for the axles are OK. I have rear axle code 45 which indicates it's not limited slip, however most of the synthetic gear lubes have limited slip additives. A quick check to the Ford axle lube chart indicates no need for friction modifiers either. So I guess I'm wondering if I should return the gear lube I have. I have to go back to the FLAPS for grey permatex anyway.
