Got a little bit of work done this weekend.

I decided to move my power steering cooler from the drivers side inner fender to make room to mount the trans cooler there.



This spot gets quite a bit of airflow from the combination of the fan/hood louver and vents on the metalcloak fenders. If I end up needing more airflow there, I can bend an air dam to force air to the cooler. I did some research on some 4L60E forums and a lot of Bronco guys mounted their coolers there with success.

I also wanted it on the driver side so I can move the cooler lines to the driver side frame rail. They are currently on the passenger side and run right along the exhaust which is only compounding the temp issues. I originally ran it that way because that’s they way they were ran in the donor truck. Time to switch it up.

So the first thing I needed to do was move the power steering cooler. So I relocated from the inner fender to underneath the front crossmember.





Then I made some 1” brackets to mount the trans cooler on the inner fender and mounted it up. I wanted to space it to give plenty of room for airflow.






This cooler is twice the size of the stock donor truck cooler. That coupled with moving the lines away from the exhaust I think will help solve the issue. If the engine bay is too hot and this spot doesn’t work out I can move it somewhere else but I wanted to try it here first.

It was getting late, too dark to see under the Jeep and I have to drop the drivetrain to get to the cooler lines at the transmission so this is where I stopped with this project.

I moved on to swapping out the stock trans pan and installing the Derale cooling pan.

Size difference:




And installed.





I am going to have to modify my skid plate again to accept the deeper pan. I’ll either fab a drop in my flat skid like I did for the 241 tcase or I might just go with the Barnes 2” drop skid. I need to do some measuring and see how much space I need.

All that’s left is to run the cooler lines, fill her up, take it for a test drive and see what the temps are doing.

8000 RPM rating? Yeah that should be sufficient lol. That thing looks nice. Maybe I’ll throw one on when I swap grills just because. Good looking out John.

I got all the transmission lines moved over to the passenger side frame rail and hooked up to the new plate cooler and moved my temp sensor to the new derale pan.







This location gets plenty of airflow. I placed my hand behind the cooler and I could feel the air from the fan blowing through at a pretty good speed.



Then I took it for a drive up I70 into the mountains then back down through the city to make sure I hit plenty of stop lights. The combo of new cooling pan, bigger cooler and relocation of the cooler lines made a huge difference. My temp never got above 170.

When I got back home, I let it sit running in my garage for 35 mins and the temp stayed right at 160 the entire time. That gives me hope that I can keep the transmission cool while crawling.




In other news, the backlight on my gauges went out, not sure whatís going on there so I will have to do some digging. My engine temp gauge also started going in and out intermittently so I need to look at that as well. I ordered a new sensor in case thatís the issue.

I also figured out my throttle issues. When I did the tub swap, I was in my buddies garage and was trying to do things quickly and I just didnít get the throttle cable pulled all the way through. I had ordered a new one last summer, so I went ahead swapped it out tonight so all is good there.

List is getting shorter...
- paint tailgate
- paint windshield frame and get new glass
- paint grill and swap out
- paint flares
- add cage frame tie ins
- add decals

I sure will be happy to wrap this thing up and just drive it.

You may have covered this somewhere along the lines here, but I will ask anyway... Are you running the trans fluid through the radiator still or just the remote cooler? If through the radiator, is it going through the radiator, then the auxiliary cooler, and back to the trans? I am not even sure how I ran mine, but may need to revisit it again as I am getting pretty high temps in the serious stuff. Must of the trails I was able to keep in under 210, but I had to give up on one spot because my temp got to 250.

I have it run in series with the radiator cooler. It goes from the tranny straight into the radiator then into the cooler and back to the tranny.

If I lived in a warm climate, Iíd bypass the radiator to keep it cooler. But since itís cold here half of the year, the radiator helps warm up the fluid in the winter.

Jmart2119's Black Beauty Build

Well I was gettin pretty sick of working on this Jeep again so since itís drivable I decided to go up and just do an easy scenic trail near Mt Evans. I remembered why I love this Jeep so much.



Everything went pretty well for a shakedown run. Transmission only went above 200į one time on a steep uphill climb. The rest of the two hour long trail it sat right at 190į.

Engine temps also stayed down with the cooler out of the way. Held firm at 210į the whole trail, even on the climb.

I parked it in the garage when I got back and didnít go back out til Tuesday. I had a puddle of coolant on the floor so maybe that radiator is leaking after all. Iíll have to look into it.

Engine was also running pretty rich up I70. Gas smell was pretty prevalent and throttle was non responsive so I need to dig a little into that at some point.

Decided to power through the final grunt work pieces and got the grill and tailgate sanded down and then primed, wet sanded, painted and clear coated those along with the new windshield frame.














Gonna let these hang dry for about a week and then get to reinstalling all of them so I can wrap this tub swap project up.

Iíll eventually need to sand and repaint both sets of doors and the rear flares but it is not high on the priority list.

I called Speedhut and the backlight going out on my gauges is consistent with inverter failure so they sent me a new wiring harness. Just need to get around to putting that in.

And then reinstall my air tank and run new air lines and redo my rock lights.

Getting close!

Knocking out a few small things when I have some spare time.

Got the newly painted tailgate mounted up.



And used two tailgate bushings to reduce annoying tire carrier rattle.



New glass and seals in the newly painted windshield frame.



Also ordered up a Factor 55 flat link to replace my broken winch hook.



And a front license plate relocation bracket that mounts to the winch fairlead to get my license plate out of the rocks.

Got the new windshield frame mounted up and wired up/installed the new light pods. With everything having fresh paint, the hood color doesnít match because I used a different shade so I plan to sand that and throw a fresh coat on so everything matches.



Threw on the new factor 55 and front license plate bracket.












Iíve got some pretty bad death wobble going on again. My ball joints and hubs were replaced last summer so I decided it was time to get some new Heims for the steering.

After tearing apart the steering, Iím pretty confident the Heims are causing the problem. They were all rusted/seized solid to the DOM.

I want to clean up the threads so I picked up a right hand thread tap but couldnít find a left hand thread tap local so I ordered one up. Should be here tomorrow.

I got the right hand threads all cleaned up, then sanded down the tie rod and drag link for a new coat of paint while I wait for the left hand thread tap.





After I get this steering back together, Iíll throw the new grill on and then there are just a few things left to do.

Rock lights, re-install my OBA tank and re-run air lines, frame tie-ins and make an engine skid.
