Transmission leaks when towing
This is probably not the place for this post but I'm curious if anyone has experienced this. My tow vehicle is a 2002 Ford 250, 7.3 Powerstroke diesel. I'm towing a 7000 travel trailer. The problem is...

A lot of heat comes from an unlocked torque converter which happens a lot on Ford 4 speed transmissions towing and running in 4th gear. Cheap solution is lock out OD, but that spins the engine pretty fast. Have read that Banks makes a plug in controller for this transmission that increases shift points and keeps the converter locked more of the time all of which reduces heat. Just another option.
I have one on my E4OD. It increases line pressure, reprogrrams the shift points and locks the torque converter sooner and keeps it locked longer. Downside is it shifts much harder, you have to be careful on the 1-2 upshift and take you foot of the fuel pedal when it shifts which isn't a big annoyance but is necessary.
My box was rebuilt with metallic clutch plates and a modified valve body to begin with so my shifts may be 'harder' that the average box.
It's an easy install too.... watched them do it, took about 10 minutes.
The harder it shifts the less slippage there is, the less heat produced.
My box was refitted by Ford SVO along with the full Banks Kit (ata-quick spool turbo, chip, K&N tuned intake. They also installed a Detroit Tru-Trak locker in the back replacing the Ford limited slip and an ARB air actuated locker in the front. I tossed the Warn/Ford lockout hubs for a set of Mile Markers.
