Can someone advise the proper type of grease used on the pcm and transmission module pins? Thanks.
Use common dielectric grease (electrical-grade silicone grease). Keeps moisture/oxygen away from the mating metal surfaces (eliminates oxidation), and the spring pressure built into the contacts is enough to push thru the grease for good electrical contact. The auto parts stores have those Permatex foil envelopes at the cash registers - I think it's labeled connector grease or electrical contact grease - something like that.
