Since purchasing a new radiator (Koyo) without automatic transmission cooler lines, I knew I needed to install a remote cooler. This thread sure helped me alot, so I thought I would share my experiences. Like the OP, I purchased B&M's model 70268. I have a 4EAT.
Here are the cooler lines:
Here I am, making SURE which line is the supply line (preparing to flush, and knowing which line to attach the new temperature sensor):
Now that I know which is the return line, I am pushing all of the oil back into the transmission.
Here I installed the supplied metal brackets. I couldn't bring myself to use the plastic zip ties and risk piercing my A/C condenser.
Bottom view. For me, mounting the cooler with the lines at the bottom resulted in fewer bends of the oil hoses, with less stress on them.
My homemade temperature manifold. I couldn't bring myself to pay $40 for the one at Egauges.com which didn't even have the barb splices I needed for the hoses, so I built my own. The parts I bought at Lowes were:
1. Brass Tee $5.64
2. Brass Elbow $4.23
3. Barb x MIP adapter $2.61 x 2 = $5.22
Total $15.09 x 9% tax = $16.45
Fully assembled manifold ready for installation (I used SubaJew's idea of reusing some of the old transmission line to reduce the chance of kinks):
Manifold installed on car with wiring completed:
I used a water temp gauge to measure the trans temp, because my local auto parts store only had this in stock:
Thank you all for your help on this!
