Atf And Filter For 4 Speed Hd

[davzog]

Thought I would pass this along....

 

I am planning to change the tranny fluid in my 07 Classic with the 4L80E (?) at 20k miles.

 

I checked a few auto parts places and the dealer (ugh!) for Dexron VI and a filter kit...ouch!

 

I went to Amazon.com and got a six pack of Pennzoil dexron VI for $33 and a Wix Tranny filter for $17...free shipping and no sales tax....

 

Seemed like a good deal to me....

 

By the way, it just occurred to me that I have six quarts comiing...is that enough??

It all depends on if you plan to do a flush or if you just plan to drop the pan and change the filter and add the 6 quarts of oil back in. If you are doing a flush you will need more like 14 to 16 quarts. My 2006 GMC Sierra 2500HD 6.0L 4L80E took 16 quarts after a tranny flush. Hopefully that helps you out....
