Changing all my fluids/filers - - first time, need advice
I recentely purchased a 2006 6.0L Manual. It has only 31,000 miles on it, however, I want to change all the fluids to synthetics anyways since it's coming up on 5 years since the build date and I figure it would be a wise thing to do. After a lot of researching on these forums, I think I have decided I am going to change the following with these fluids.
Engine - Rotella T5
Transmission - 75w-90 Amsoil Manual Transmission and Transaxle Gear Lube Synthetic
Transfer Case - Synthetic ATF
Front/Rear Diffs - 75w-140 Severe Gear Synthetic
Coolant Rotella ELC
I'll be using stock motomaster fuel filters, air filters and oil filters. How does this all look?
I have decided to use 75w-140 in both front and rear because I have heard this is the new norm and the dealers are doing this. But should I stick with 75w-90 in the front?
Also, the transmission fluid. My manual recommends ATF, but the new 2008+ ZF6 are using the 75w-90 oil specified above. I feel a lot more comfortable using gear oil rather than ATF.
Question... since both the Tranny and T-Case originally were spec'd to use ATF, but now the tranny has switched to 75w-90, can I also switch the t-case to 75w-90? Or is that a no no? I know the t-case is a lot different than the tranny, in the sense that oil isn't as important but wondering if I could do this.
Last question, is there anything I need to know when doing all of this? Any tips for installing the fuel filters, or doing the diffs? Do I need to take the covers off the diffs to drain the oil and fill, or are there plugs? How easy is it to drain and fill the manual tranny and t-case?
