is the vdo gauge sender going in the sump or in the cooling line?
I vote for trans cooler first then radiator cooler and keep the oem air cooler for the power steering a la gojeep.
1. this helps the trans reach operating temp quickly in especially in winter
2. Seriously hot oil temps of 105C+ will still lose heat in the radiator
I don't like the idea of bypassing the radiator cooler unless there is an independent fan on the aftermarket oil cooler.
....take cover hear come CARVS....
Ps I have the gojeep oil cooler
(about $80 landed in Australia at the moment)and taurus fan and it works great,
trans sump temps are mostly 80 occasionally gets to 90 yet to see 100.
I am sure that there are other ways of doing it that will also work.
Good luck with it.
