Just finished replacing the FoMoCo cooler with the B&M #70266, the transmission filter and installed a drain plug on the pan.
I'm glad I did all this but it was a bit of a chore! The fittings on the cooler are not the same as on the Ford cooler so I had to find a shop that could help. Was successful at the 3rd shop I went to!
It took some time to mount the cooler as well. I didn't want to use the kit and attach it to the rad. I made a bracket instead which worked out real nice but all this took time.
With AjRagno and jlcotney's pics, I decided to put the plug, dead center at the bottom of the pan. Straight forward!
I only had to turn the crank and check for the torque converter bolt four times. Was lucky I guess as I could see the bolt after the first crank. I was by myself on the driveway crawling under the front to turn the crank and then would have to come around the side to get under the trany to check for the bolt.
Took 12 L of Mercron V and 6 hrs of my time. Still have to do a clean-up tomorrow.
It was worth it! The fluid and filter were dirty and the fluid had a smell to it. Lots of slug around the magnet and on the bottom of the pan. I did have a flush done last spring but I think I may have cooked the fluid somewhat while towing. My tran temp guage is an electrial one installed in the test port. I was getting readings as high as 210* while towing. During the test run, after all this work, wilth the trany warmed up the temp was about 15* lower than with the FoMoCo cooler. A definite improvement!
I guess the real test will be when we head west through the Canadian Sheild in Northwestern Ontario in a few weeks with the trailer. The terrain is very rugged with lots of hills, etc. Beautiful country but puts a big load on the truck!
