When I started the project, I planned to use the stbd 8-plate bellhousing coolers for the transmissions. Mid-course, those became fuel coolers. I happen to have one of the big coolers in chrome, with the small section on hand, so that became my transmission cooler and power steering cooler. I got another log for the port side. They seemed like good replacements for the plate cooler. Might be overkill, but I figured cooler was better. I've got temp and pressure senders on the trannies. If it looks like I can't get any heat in them, I'll try to find some thermostat bypasses that work in the 130 range.
