Question:
2003 Chevy suburban 1500 base model. No current trans cooler on vehicle. Want to add cooler. Looked at your Derale Series 8000 Plate Fin model for. I watch a video on the installation where the existing cooler lines were cleaned and cut, compression fittings were installed and the new lines were connected to the cooler. Do you sell a kit with the proper size compression fittings for this install? Thank you so much, Tim
