Recently picked up an ‘87 pathy. Was told it needs the tranny serviced and possibly an ATF cooler. This is my first project vehicle on my own. I don’t have much background in mechaniking. Is this something that can be done by noob in an afternoon? My ex husband used to do all servicing of my former off road vehicle. On my own now. Scary, right? Please, be honest but not mean! Thank you!!
