Do you all have any recommendations for tranny fluid for my 5 speed? Also, what about fluid for the rear end? Thanks!

Look in owner's book :nice:

If you mean the automatic I think the specs are for TYPE WSS-M2C919-E (E-fluid) For both the 4.0 & 4.6 Altho I also see a reference to using MERCON V automtaic trans fluid only and the type of fluid will indicated on the fluid pan.

Hope this helps.
