10W40 works great in Southern Cal. Good for Death Valley summer, and down to 20F easy, 10F with good battery.
If you are going up into snow country 10W30. for down to 0F.
No reason to use synthetic transmission fluid--almost ALL the base oil in Dexron III is 'synthetic' to meet the low temp viscosity specs. Add 1 pint of Lubegard RED to the transmission after a FLUSH, then pan drop and filter clean (its a metal screen that is easy to wash clean. it is just to catch chunks of friction disk material. If the transmission is generating metal that's filterable, its toast anyway. Do replace the OEM transmission filter (down low in front of battery). AMSOIL IS great stuff. However, unless you are going to do lots of driving, you will not get any where near 25K miles/change B4 time (6mo max) is up. Personally, I prefer premium quality 'conventional' Valvoline 10W40 changed 4000 miles 6 months max in summer, 10W30 4 months max in winter.
