Hi guys
Ive recently got myself a new (
well near new 30k on the clock) dual cab and it has a 6 speed auto transmission.
Ive bought myself a auxillary transmission cooler kit to help keep things cool in the trany dept.
I want to run it in series with the existing transmission cooler which is part of the radiator (EG make use of new auxillary tran cooler AND main radiator)
QUESTION
should i run the new auxillary auto transmission cooler in circuit before the radiator or after ?
My thought would be to cool the trany fluid down BEFORE it goes through the radiator to assist also with the reduction of heat going into the engines coolant and to also keep the motor coolant cooler.
BUT the instruction with the kit say for a series connection to install the auxillary tranny cooler AFTER the radiator..may be their way of thining is to remove as much heat with the radiator coolant so the transmission fluid it can be as cool as possible before returning to the transmission.
any thoughts
Many thanks in advance
John

As you have stated
John. Between the transmission outlet and the radiator cooler inlet, i.e. before the radiator.
Advantages of removing excess heat that may impact on the radiator's ability to control the engine coolant temperature's in high ambients when towing and also to allow some heat to be re-introduced to the transmission fluid if operating in extreme cold.
Although I can't think of an area in Australia where that may be strictly required.
I guess let's go back to the basic idea of installing an auxiliary cooler in the first place.
The removal of excess heat that may be beyond the ability of the whole vehicle's cooling system to handle in extreme conditions. What's the point of removing any heat after the engine cooling system has possibly been over worked.
