I am getting a free TH350 from my father in law. It was in his 68 corvette and seemed to drive fine when in it. The mileage is unknown on it and I know he is pretty hard on his cars. My question is, should I take it into a tranny shop and have it inspected before using it? Any things that I should take a look at first? I already have a new torque converter for it but was wondering if there is anything else to check out? Thanks
