Could this work on a 2008 Chevy Tahoe with factory trans cooler

[@mishimoto]

This will fit the Chevrolet Tahoe V8 2000-2008

I have 2004 Chevy Silverado 2500 and would love something like this. My little cooler just doesn't keep up when I am pulling my trailer up the grades. Will this work for my truck?

@@mishimotowhat about 2005 Silverado 2500hd 4l80e

[@chrisburton1117]

I have a 03 suburban 3/4 ton with the 4L80E tranny. With my model would the lines mount to the cooler or would i need different lines?

[@mishimoto]

Shouldn't have an issue as long as you have the GMT800 or GMT900 chassis with the V8 engine. Thanks!

[@chrisburton1117]

Thank you 💯👌​@@mishimoto

Do i need to flip the pill on my thermal bypass with this or is there no need?

[@mishimoto]

There is no mention of this on the installation guide.

I have a 2002 sierra with a 5.3, but my trans cooler is built into the radiator, would this product still work if i got longer hoses?

How much extra transmission fluid does it need to be added after instalation?

[@mishimoto]

0.65 quarts

[@giovannygarcia2653]

I bought your cooler but found out I don’t have the lines to connect to it any idea where I can get them ?

[@mishimoto]

We'd suggest reaching out to the team directly at [e-mail] and we will be happy to help!

It means your vehicle didn't have the tow package with the trans cooler. You can run rubber lines that go to the radiator trans lines, bypassing the radiator and go through the trans cooler. Or run a rubber line from radiator trans outlet to input on new cooler, the from outlet back to the return trans line. Only bypass radiator if you live in a warmer climate.
