Dropping the transmission pan appears straightforward...which worries me. Just disconnect cooler lines and filler tube?

I've always treated transmissions like electrical systems: sleeping demons not to be disturbed unless absolutely necessary, and then only with much trepidation. And a sacrificial goat if one is available. If I drain the torque converter, are there parts to be routinely cleaned/replaced?Yup new gasket and screen are readily available through various sources. Also torque converter is pretty simple to drain as well. Remove inspection cover from bell housing, rotate converter to find drain plug,remove, rotate another 180 degrees and remove other plug.
messy but fairly straight forward.
good luck. Refill is 10 1/2 quarts type F trans fluid. Add about 4 quarts start up for a short bit shut down and add balance of fluid.
good luck.
According to the Ford-O-Matic Shop Manual, the transmission fluid should be changed at 15,000 mile intervals. Other than what 1957Bird has already told you, after thoroughly cleaning the transmission pan, you will want to replace the filter also. The filter is held in place by a metal retainer. After removing the retainer the filter can be removed from the filter tube. Included with the filter are two o-rings that belong on each end of the filter tube. Make sure the filter you purchase is for a Thunderbird Ford-O-Matic. There is a difference in length between the Thunderbird transmission filter and the passenger car filter.I've always treated transmissions like electrical systems: sleeping demons not to be disturbed unless absolutely necessary, and then only with much trepidation.
