Just bought 2007 don't no what fluids in the tranny now can I drain pan change filter and a different fluid in maybe some thing better thinking there would be two different fluids mixed would that be bad I would assume it has standard fluid type 6 I think but don't no
What I was trying to ask is if I drain the transmission all fluid doesn't come out right
If I refill with transynd it would be mixed with dex 6 or what ever is in it now just wondered if that would be a problem as for posting thought posted in wrong spot sorry if I irritated you trying to learn how to do this
For your Diffs, I recommend AMSOIL Severe Gear 75W-90. It is a full synthetic that is a highly shear stable and has a 100k drain interval. You will need 2 qts for the front and just over 3 for the back.
For the tranny I recommend AMSOIL Torque Drive. This gets debated a lot but Torque Drive and Castrol Transynd are the same fluids. You can do a drain and fill no problem. It will require another drain and fill after 50k miles.
If I can answer any questions or help with pricing, please give me a call.
