i have a 03 silverado 1500 and i wanting to install a trans cooler but not really sure which to go with or how to go about it any help would be great

 

This is what most people go with including me.
4L60E 700R4 4L80E 4R100 E4OD 2004R C6 TH350 TH400 Transmission Parts: TRU-COOL 40,000 GVW TRANSMISSION COOLER

 

ok cool how hard is the install on the tru cool / i have never put on in before ?

 

It was pretty easy, it comes with some metal straps to mount it and all you need to get is some hose to run from the stock cooler lines to the supplied barb fittings. If you search on here there are a few posts about people installing them.
