My mom's 1964 Galaxie 500, 289, C-4 trans won't shift into 3rd.
The car was not driven for 3 years while other work was done to it. No leaks or low fluid level. Fluid is nice and pink with no bad smell.
Is something just stuck open or shut due to sitting? Will driving it regularly free it up?
It should be noted that the transmission worked perfectly before it stopped being driven. It had been rebuiltsome time back and has less than 10,000 miles on it. Probably 5000.
