Allison Aux Trans Cooler To Replace Stock 4l80e Cooler?


Recommended Posts

Posted

I have a 2000 2500HD 6.0L and want to add a larger aux trans cooler. My stocker is about 10" wide and 5-6" tall. I was wondering if the Duramax/Allison aux trans coolers might bolt right in. I am assuming they are larger (maybe a bad assumption. I have a Long cooler that is about twice as tall with the same spacing. Not sure what it came from but I was going to see if it will fit if necessary/.

 

I have no problem with going aftermarket but I was was thinking this might be a clean upgrade.

Just go with an aftermarket Hayden 679. Cheaper, and there are plenty of install threads on here for you to research...

Yeah, they are pretty cheap. I have a 1.5" thick 10 x 11 Long I might install. Looks like the stacked plate Haydens are Longs anyway.

 

I was just curious if the high flow Allison would fit.
