Fits 8.1 with minor modification

Bought for 2001 Silverado 2500hd ecsb Allison transmission, 4x4, 8.1 vortec. The fitting the goes into transmission is about 1/2” from the exhaust right at the elbow of the fitting. Then I had an aftermarket cooler so I had to notch out a section of the radiator support or front assembly frame. Not sure what to call it. Right where the line comes out of the cooler on the passenger side it goes directly straight down. Might work with a stock cooler. I imagine it is the same with the duramax. Literally the same truck except for the engine and torque converter. Not sure why that wasn’t worked out. But very minor trimming and fits perfectly.

I sell this to all my dmax customers

Great lines a lot easier to install than the hard rigid lines and will last longer.

Install

Super easy install! Took maybe 2 hours from start to finish and was back on the road. You will loose a little bit of fluid so just have extra to top it back off.
