Unfortunately, without access to a repair manual specific to that year and model, I can't pinpoint it precisely. You'll need to:
* Consult your owner's manual: This is your best resource. It will show diagrams and explain the procedure.
* Look under the hood: Systematically examine the transmission (it's the large unit behind the engine) and the surrounding area for a dipstick with markings indicating "Transmission Fluid" or a fill port that looks appropriate (often a capped tube). The dipstick may be colored differently, such as bright yellow or red, to distinguish it from the engine oil dipstick.
* Use a flashlight: It can be dark under the hood; good lighting is essential.
* Online resources: Search for "1991 Chrysler New Yorker transmission fluid location" along with images. This may reveal pictures showing the dipstick or fill point.
Important Warning: Incorrectly adding transmission fluid can damage your transmission. If you are unsure, it's best to take your car to a qualified mechanic.
