---Greg: the OEM on the Oil cooler, is it from a 430 or 'another' model from older vintage or such.
Not from a 430. It's the same as what is used on the Challenge car but with an special electric fan attached with a non-invasive temp sensor (no leak possibility).
---LASTLY: What do the CHALLENGE cars use? Why not just go that route?
It's air cooled by a scoup on the engine hatch. That can't work on a street car unless you are going more than 100 mph. Now for you, Rik, that's not a problem, but for most of us it is!
The entire kit from me has everything required. It's a bolt-on assembly that just takes a little time.
Coolant has to be drained down a bit, OEM heat exchanger removed and replaced with supplied hose and clamps, OEM oil lines rerouted, electic feed installed, cooler mounted, lines attached, electric connected, tranny oil refilled, coolant added and bled, car driven a bit, then air bled from tranny by means of opening tranny fill port, adding a bit more tranny fluid (maybe), and that's it.
Tranny temp runs 47 degrees cooler, engine runs cooler cause no tranny heat inserted and coolant water flows more efficiently.
With the addition of Redline tranny oil that gearbox is a seeing a new life and no longer any fear of coolant water getting in.
I had been working on this for a while before my friend's system blew up. I had anticipated this happening. What a mess and what a cost!
