Nice, I'm NA with only spirited street driving and using the same Hayden core Z1 uses in their kit (purchased elsewhere), rubber lines with oetiker stepless and ABA Awab clamps which are stronger and provide for a better seal than T-bolts and without leaks.

I'm bypassing the OE "cooler" as my current summer trans. temps. are 122*-172* via gauge in the hot line coming from the trans.; therefore, the aftermarket cooler would be fighting the OE cooler heating the fluid to whatever my coolant temp is, typically 175-190* (170* stat.) which is obviously counterproductive.

Be careful not to cool under 122* as OE torque converter lockup is 122*-176*. Outside of this range your fuel mileage will suffer so you definitely want to be within this temp. range on the highway. In winter I have to block some of my cooler to keep temps. above 122*!

Are you using the VR transmission yet or still OE?

That's a nice line kit

and a good solution for those with leaky and/or degrading rubber lines.
