Re: Hole on side of trans tunnel?

Cadillac had the same set up on the Hydramatic only it was on the right hand side and had an access cover. The fluid drive Chryslers had only a plug in the fluid coupling which was also accessed via a floorboard cover and plug.

Given Packard dealers relied very heavily on service for revenue it is fitting that the Ultramaitc would require trained personnel for even routine maintenance. Thus, the location of the dipstick. After trade in the Ultramatic could be very troublesome given it would then end up running low on fluid if leaking.

If the pan is leaking use Mopar ATF-RTV and let the sealer sit for twenty four hours before filling (and use a torque wrench). If the trans is throwing oil out the vent, there is a service bulletin as regards the speedometer gear. If it is installed backwards that will cause problems. I have been told as well that if the filler cap is not vented it will throw oil.

After that there is the front pump seal, TV, tail shaft housing, and shifter.

I have taken care of leaking Ultramatics and had the cars sitting for weeks without a drop of leakage. So they will hold oil.

Today, they are omitting transmission dipsticks altogether.

Hope this helps.
