4L80e transmission lines!
 
1 Attachment(s)
Anybody have a picture of the correct factory hard lines going into the raditor from a 4L80e transmission, like on a stock c20 (99-06) Silverado? I am trying to put a 4L80e into my Squarebody but the hard lines are WAY off (like the hard lines were misbuilt-they are not lining up with anything).It would be really helpful if I had a picture of how the factory did their tranny lines to the Radiator

I am looking for a photo similiar to the one below with the yellow circle around them, but with both hard lines shown?

Re: $L80e transmission lines!
 
T800 4L80E lines will be JiffyTite push in fittings.
There should be three lines. Two long and one short.
  1. From the transmission to the Radiator cooling loop then.
  2. To the AUX cooler.
  3. Out of the AUX back to the transmission.

I would use an external cooler if you tow with it.
There's an upgrade setup for installing the Hayden TruCool LPD cooler using the JiffyTite fittings.

If you have a Mastercool hydraulic tool you can make up your own JiffyTite lines to screw in fittings.

Thank you!

I obtained this picture which I believe shows the lines as the factory would have shipped it?
