I'm a moderately skillled mechanic, 51 years old. The car moves in 1st and reverse only (if you put the shifter in 1, not in D). The fluid is black, the previous owner purportedly had gotten it stuck. I don't want to buy a used transmission that is on the way out. So, am I better off personally repairing the one I have, since it has to come out of the car anyway?
Please, I would really appreciate comments from skilled Ford or automatic transmission mechanics only. For example, do I need expensive special tools to replace the necessary parts? Thanks.
