Anybody Replaced HP fluid with Amsoil?

[Black02Silverado]

AMSOIL's  ATL transmission fluid works on both the 6sp and 8sp transmission.  This is a full synthetic fluid and you can use it with out any worries. 

 

Now the new 10sp requires a completely different fluid and AMSOIL does not have one for that application as of now, but they are working on one.

 

You can use AMSOIL's ATL with confidence. 

 

Anyone want a quote for ATL just send me a PM.  All GM-Truck members get a discount.

I would advise against using it. Amsoil shows that fluid as being both Dexron 6 and HP compliant, yet Dexron 6 is NOT compatible with Dexron HP.
