I picked up a 4l80e. It came out of a 2002 silverado (i saw the truck as they were pulling it out). I keep reading that after 1997, they moved a trans line fitting to the back of the trans? Mine has both holes on the side. What year do I have? Im trying to figure out what fittings I need for my -6an lines since the newer ones require the one with the tube. Thanks.

it says GM-B9 in the casting

 

That's a 2002, one line on front and one at rear (red caps) the 2BSP signifies it's a 2002.

 

russel part # 640520 1/4 NPSM to -6an...

 

In fact it came out of a 2002 6.0 K series.

 

awesome haha. Thanks guys. I guess the "moved a fitting the rear" threw me off as its the first time ive really looked a 4l80e out of a vehicle

 

found these
6AN 4L80E GM Transmission Cooler Fittings | eBay

 

Yep those are the ones that you want if the cooler fittings are spaced apart. If the fittings are both the front then you need different fittings.

 

I think those are for the early year 80E's.

 

Correct, that Russell part number is not for the newer style. Do not use that.

 

what is the difference in fittings? my trans looks just like that but it did not of have top bell housing bolt hole. i hope i have the right fittings.
