Powerglide - Dedenbear/TH400/700R4/4L60/4L60E/4L80E (1991-1996), AND (fittings are upper/out-lower/in- on the Th200/TH200C Metric, and 2004R)
Thread Size.........¼” Pipe......¼” Pipe
Flow Direction......Return/in....Cooler feed/out
These are the threads in the transmission case and they are almost always equipped with an adapter to allow the use of a 45 degree flared steel line.
The lines are either 1/4 or 5/16, I have seen both, and I have also used a pipe fitting to hose barb in the case myself.
It would be best to take the line out of the fitting adapter and size it for yourself at the parts store, this way you KNOW you have the right one the first time.
