Have a 4l80e (first gen?) Transmission and it doesn't go in reverse. So took pan, gasket, filter etc out to get to the reverse servo assembly.
Took that apart and checked the servo pin (seems pin I have is D/C so can't find replacement or specs)
Also inspected pin and looks good. So wondering If it's the "bigger" spring in the reverse servo assembly but can't find specific, part number or name etc.
Can anyone help please? I don't want to buy a whole "kit" if I just need one spring. Or the servo assembly isn't the issue...
First spring. Not second. Ordered second by part # but not one I now know I need.
Thanks for your help
