How hard is it to do tranny seal?

[BusterB]

so my 91 explorer 4x4 is getting a pretty good steady oil dip from the tranny seal... how hard is it to replace on your own can it be done with-out removing the tranny completely out from vehicle seeing as it is quite big? or whats some options? all the help appreciated.....

Which seal are you referring to? Is it the front seal?

I have a decent leak there too (where the bell housing meets the engine). It never leaves drops on the driveway, but it leaks while I drive it (when it's warm). I got 200k+ on mine and it's barely down a quart by the time it's due for an oil change. I'm not sure the easiest way to do it, but I'm pretty sure it's not gonna be easy to do, regardless, heh. I'm gonna try putting some Lucas oil treatment/stabilizer in it my next change and see if it helps the seal a little. I've heard from a lot of other people that this stuff does wonders.

The Lucas is a temporary fix, and it won't work if you have a cracked crankshaft to flexplate spacer or a worn pump bushing. It is designed to swell the front seal to make a tighter fit. It won't work if the seal is shot.

I know, but it can't hurt, right?

You could try some, but don't over do it. How many miles do you have?

205k now.

I was just gonna replace a quart with the Lucas stabilizer (what it directs on the bottle, I believe). That too much?

umm....well.....I know it's probably unrelated to the lucas, but the front seal was leaking on my '92 and I popped a bottle of the lucas transmission stuff in it, two days later the seal blew out while my wife was driving it, lack of fluid led to it messing quite a bit up inside, after stuffing fluid into it the truck to get it home its like it was stuck in drive, no reverse it would only move forward. That led to the purchase of a parts truck with a decent low mileage transmission
