ATF complete change with transmission fluid cooler

[ianmac23]

I am at 45,000 miles and wanted to do a complete fluid change at 50,000 to Amsoil products. I did a search and could not find a write up for a ATF change with a transmission cooler. I did find this from Amsoil http://www.amsoil.co..._Procedures.pdf. Has anyone done one? Do you know which tube is the return line from the cooler? Any help of tips would be great.

 

Thanks for your help

Ian

Upper line on radiator is output to the aux. cooler. The other line coming from the aux. cooler heads straight back to the trans. With this info you should be able to figure it out.

This is an after market replacement for a factory cooler on a 2000 Silverado but it should still be the same. The line on the right, which is the drivers side of the vehicle is the return line back to the transmission.

Thank you both.....Black02Silverado by your signature I assume that you use Amsoil. I just got a commercial account and look forward to using Amsoil. I have run Mobile One everything for years. How do you like Amsoil?
