This is the last of a two part video showing how I diagnosed and repaired an ATF oil leak between the 231 HD transfer case and the 46RE automatic transmission of a 1998 Dodge Ram. A link to part one is embedded in the first few seconds of this video, and here:
Both parts are lubricated with ATF+4, and the leak occurred at the weep hole between the two parts. Even in retrospect it is difficult to say which seal was leaking, or whether it was leaking at the bearing retainer plate. This type of leak may seem to be coming from the transfer case, since gravity and surface tension draws oil droplets down and back from the source of the leak. Ultimately I removed the transfer case and replaced the front seal of the transfer case, the rear seal of the transmission, and I refreshed an RTV seal at the front transfer case bearing retainer. Details of the repair are shown in a step wise fashion.
At the end of the video I describe how I will adjust the automatic transmission bands and change the transmission oil in a future video, link to come.
For further reference, a discussion thread and still photos of this repair are also available at dodgeforumsdotcom, here (replace each dot with a period)
