Hi,If the push button actuates the other gears it must also actuates the R. Do you have try to put the rear of car on hoists and see if the wheels turn in reverse at normal speed...1) the push button for reverse is not actuating the cam/control cable to shift in to reverse gear, you need the R band in R but also in 1 position (not in the 1st of Drive or "breakaway"). If the 1 position is ok, itsn't the band2) the reverse band could be broken (first & reverse are actuated by the same gear?) Maybe ?3) a valve body problem. I think also at a rear clutch problem or a too low line pressure in R: the line pressure needed in R is twice the forward line pressure. I remember of a car (NY 1957) who has a lot of problem in R: the pressure was too low because the front pump was weaked. Best would be to take the line pressure in D and in R (with rear wheels off the ground) --
