The original poster probably used some third party host for the pics instead of uploading them directly to the forum website. It might be up to him to fix, if he's still around.
Servicing a T-28 Transmission / Borg Warner Model 8 Transmission

Hey dmf6978,
Got your PM. Yes, I believe this is the gasket..
We had difficult with leaks as well, even with the correct gasket. So what we did was clean all surfaces on the pan and tranny. Perfectly dry and clean. Then ran a 1/8th" bead of the black RTV around both the pan and tranny. Waited for it to dry to the touch...so not tacky, but not hardened. Then sandwiched the gasket in between those and bolted. Bolted just barely hand tight.
Been running the truck and no leaks!!!
Thanks for the kind words. Hopefully the photos can be put back up, if not then I have them saved somewhere. I will have to see what admin says.
* ah, just saw his reply. The site has changed so now I need to figure how to get the photos back up.

Nothing an Admin can do. The person who originally posted these pictures needs to fix their links.
Thank you!

Hello everyone,
I also have the BorgWarner Model 8 transmission in my 1967 Travelall,
because I had to disassemble it for cleaning (the car had been sitting for over 30 years).
Unfortunately, there isn't much information about this transmission here in Germany, except for Mercedes, Jaguar, and Volvo, which also used this transmission in the 1960s.
I'm glad this report is available. Many thanks to the author.
I now have a problem:
The transmission is installed and it works fine so far. Drive (D), D1, D2, and L turn, but my reverse gear is missing.
Can anyone tell me what the problem might be?
Since no one here could tell me exactly which ATF is the right one, I was recommended ATF Dexron 3.
Is that suitable or not?
Greetings from Germany

Hi Beluga, thanks for your reply.
It will definitely stand out on German roads. As far as I know, it's one of only four Scouts in Germany, and while there are more pickups here, Travelalls are absolute rarities.
So, if I understand you correctly, you also used Dexron 3 back then?
So my problem can't be the oil.

Dexron III ATF is fine. I'm going to relay some troubleshooting tips from the factory service manual. Keep in mind that these manuals were originally intended for factory trained service techs of the day, rather than untrained owner/enthusiasts decades later.
NO DRIVE IN R POSITION
1. Fluid level low....verify correct level.
2. Manual linkage not adjusted properly....verify and correct as needed.
3. Control pressure low.....assure both control valve assembly and pressure regulator valve assembly are clean. Adjust with vacuum unit setting.
4. Rear clutch not applying....check rear clutch action with air pressure.
5. Rear band will not apply.....check rear servo action with air pressure.
6. Transition valve stuck....clean control valve assembly.
