Transmission fluid change

Unfortunately, factory automatic transmission pans don't come with a drain plug in these old trucks. (You can add one though --but it will be AFTER you initially take the pan loose).
Put your drain pan under the transmission and start loosening the pan bolts from the rear to the front. Loosen them only a little bit with the rear bolts being run out a little more than the front and break the seal the pan has to the gasket. The fluid will come pouring out
This will let the back of the pan slope down a little more than the front to make the majority of the fluid run out the back of the pan. --somewhat controlled but, still a good chance it may be messy.
Once most of the fluid has run out, you can take the pan off. Remove the old gasket material from the flange of the transmission and the pan. Swap out the filter.
This would also be a good time to put a new seal in the tail housing. If fluid is leaking out the front, from the bell housing, the transmission would have to be slid back away from the engine and the torque converter removed to change out the front seal.
There is an O-ring inside the transmission around the shift lever on the left side of the case. If it's leaking around the shaft, it would be a good time to replace it, while the pan is off.
