VPI requests require the year, make, model, trim level, engine size, engine HP, Drive type (FWD, RWD, AWD, 4x4), auto or manual transmission, car weight, and all options.

2023-02-25 - Aluminum radiator with transmission cooler

Our car has a transmission cooler built in to the stock radiator that we use to cool engine oil (example rad pictured - the two fittings at the bottom). We are considering going to an aluminum radiator since our rad died
1. Can we buy one with a similar built in trans/oil cooler and still meet the free aluminum rad rule?
2. Can we use the aluminum one but run a separate trans/oil cooler (much cheaper option) but understandable if not allowed?

#1. Yes, you can buy an aluminum radiator with built in transmission cooler and meet the free aluminum radiator rule (if your car came with the transmission cooler on the OE radiator)
#2. No,  you cannot run a separate trans/oil cooler unless you claim appropriate points.
