Product Q&A

Hi wondering if these work with the factory 04 single cab short box sierra 4x4 trucks with the external transmission cooler at the very front ? My short line from the trans cooler to the radiator is still in good condition.John johnMar 16, 2024

Best Answer:Hi Aaron, I'm glad to assist you. The fitment details must match, which mentions "4-speed, automatic transmission, transmission mfr code 4L60-E, except heavy duty trans cooling system (KNP)." It should be the correct transmission cooler line if it match the fitment details (as I checked the vehicle application). Grab our sale price and click the link below to buy it today.

I have a 2006 GMC Sierra 5.3 2WD . Bought an Upper Transmission Cooler Line Replacement From Autozone (DorMan) & won’t fit like the original. It’s mainly for the small Cooler/Radiator in the very front of my truck & im hoping it’s the upper line that’s connected on the right side. I just don’t want to keep buying the wrong one. I was wondering if I’m right & this will fit like the original?David H.Dec 25, 2023

Best Answer:Hi David, I'm glad to assist you. This pair of transmission cooler lines says it's for non-heavy-duty type (KNP). If the cooler lines look similar, they should be compatible (no note if upper, lower, or a combination of both). If your car appears in the vehicle fitment information below, it is a guaranteed fit part. Grab our lowest price and click the link below to buy it today.

Will these lines fit my 2007 Chevy Silverado LS 1500 Z71 4×4 4 door ?Ashley H.Oct 12, 2023

Best Answer:Hi Ashley, I'm glad to assist you. No, they won't. We don't have transmission oil lines available for the 2007 Silverado 1500. We suggest checking the local part stores around your area on what they have available to offer you. I hope this helps, and we thank you for inquiring.
