Transmission won't engage park,rev or drive gears
Stock transmission....Rebuilt 350(unsure of year)
Just acquired 86 El Camino. Just started engine after PO
Added 350 to stock transmission....Rolls in all gear selections from park to low.
Linkage is connected and engaging gear selector on tranny
correctly....Unhooked linkage and manually changed gear selector. No joy...
Not sure where to begin.....Fluid level correct...Noticed a new torque converter
has been installed.
