ok on the factory radiator. which is the feed line and which is the return line.

the top or the bottom?

and do i want my trany temp sensor before the cooler or after the cooler?

the line that goes to the top of the radiator is the feed line, and the one that comes out the bottom is the return line to the transmission

Not really. Trans fluid enters the radiator cooler bottom line.
Easy way to remember: the two fluids flow in opposite directions--coolant flows down, trans fluid flows up.

If you want to mount the temp sensor in the cooler line to read max temp, it should go in the bottom line (fluid TO cooler)

so trany flow up. ok sensor in bottom line.

now nother questions. i am putting a tranny cooler on. do i bypass the stock on all together. of do i go trany- after market- stock -tranny or the other way. tranny - stock - after market- tranny.

and why does the sensor go in that set up?

thanks

Whether you bypass the cooler in the radiator is up to you.

If you use both coolers, put the aux cooler in the line out of the radiator, the top line.

The temp sensor should still go in the bottom line before any coolers.

So it's transmission>temp sensor> stock cooler> aux cooler> trans.

I just remembered this:

is it good or bad to bypass it? you said it is up to me. but what do you guys do?

A lot of places recommend to not use the one in the radiator, partially because it can fail and contaminate the trans fluid with coolant. Coolant eats away at the glue that holds the friction material on the clutches. I've had that happen on the garage floor. In less than 8 hours the friction material would flake right off an old clutch that was on the floor in it.

As far as operation. I put a new radiator in my one ton truck with a 4L80E so I connected the radiator cooler back into the circuit and didn't really see any difference. I live where it never gets very cold though too. If you live where it gets very cold often you might want to keep the radiator cooler in the circuit.

My A4 camaro has an M6 radiator so I have a stand alone cooler, it seems to work ok.
Of all the vehicles I've built up and driven I can say running it through the radiator cooler doesn't really do much that I've noticed.

I'd run it without the radiator cooler. I'm in FL right now and it hardly gets to 32 so I can't say as of recently but I'm sure I've run something colder before without a problem.

i run just the cooler i have i believe a 24 something bm cooler. on a good cruise in almost 100 degree weather trans runs around 200 degrees with some racing... lol i dunno if thats good but its a built trans.. my trans temp sensor is screwwed in the side of the trans so who knows if its accurate
