4L60e was 94 I believe. 4L60 was the new name for the 700r4. Has electronic torque converter lockup. It works pretty good. Shifts a little harder than factory and holds gears longer for pulling heavy loads. Seems like it puts more power to the tires than it did before rebuild. Rebuilt because of a noise and hard shifting in 3rd & 4th. Sunshell gear was broken off causing this problem which is a common problem with the 700 trans.
No pics of truck with thornbirds on it.
