Go home without truck. Next day my mechanic calls to say he found a new pin at a tranny shop and now everything's wonderful. Tranny slips between 2nd and 3rd. No downshift at all. No passing gear.
Tranny shops says it can fix it with a band adjustment.
I'm not so sure. For really old trucks its better to not disturb sleeping dogs. I'd much rather have kept topping up the ATF than go through this nightmare. Just a recap and an update on my experience with changing the modulator valve on early model explorers. I had lots of pinging and evidence of tranny fluid in the vacuum lines.
