This is a multi-part question related to transmissions.
From what I've read on here, there are 2 schools of thought in regard to any additives, be they for fuel, oil, transmission, etc.
1st question: I have a very minor leak on my transmission, had it checked by my mechanic and he says its most likely a seal that is in the process of going bad. the leak is a few drops that form at the inspection plug on the bell housing and drip a little. So far, its only taken about a 1/4 of a quart to top off the leakage. What I would like to know is if I add Lucas Transmission Fix, which might seal the leak until I can gather up the funds to have the tranny serviced/repaired, I'm pretty sure that it will either work and stop the leak for now but will it cause any adverse effects in the long run? My Expedition is what some might call a high mileage model as it currently has 188,865 on it. By adding the Lucas to the tranny, I'm not seeing any real downside to it as it should benefit the moving parts. But I could be wrong.
2nd question: when the transmission is serviced and the seal or seals replaced, should the torque converter be replaced as well? After the tranny is put back together and during the filling process, has anyone used Lubeguard in their transmissions? I looked over the section under Product Reviews and didn't find anything. Is this stuff just snake oil in a bottle or does it actually work?
3rd question: in doing research into transmissions, I came across a mention of aftermarket larger transmission pans. I have no idea if such a thing exists for the expedition series but am interested in the event someone has installed one. Links would be great as to where they found it. While they appear to be something that would be a good addition as more fluid = more cooling ability = lower operating temps = less wear and tear on the transmission and potentially that would increase the life of the fluid and transmission. (I don't tow anything and rarely go up into the mountain where there might be a strain on the transmission)
However, what concerns me about a larger transmission pan is that the extra fluid might make the transmission work harder to pump the fluid through the system.
If anyone has any information related to any of the questions, that would be greatly appreciated.
