can anyone point me to a YouTUbe video on transmission removal on these trucks? or a good step by step guide? It's a little more involved than I thought it would be and want make sure I get it in the right order... or don't remove things that are not required.

88' 150 transmission removal on these trucks?

Please clarify: is this an automatic or manual transmission, 4-wheel or 2-wheel drive?

w150 signifies 4x4... and it is a 727 torqueflite automatic.

See if this helps. I can't get the hyperlink to work so search YouTube for the below title.
