My 740 was dripping for a while but now I see a trail of drops. I checked the oil and filled it up , maybe a tad too much , Ill check that. but I know it's been leaking and it was down a whole quart, usually I Haven't needed to add oil between changes. I think its dripping so bad now that I'm loosing so much that I need to fix it. I dont really want ot tow it to a shop to drop a thousand bucks on this issue, The costs are a concern.

Ive seen leaks in my 240 caused by a leaky oil separator box and I have also heard of them cracking. I might have a pan gasket issue but I'm kind of thinking it's the rear main oil seal.

can I suspect the drip will be more from under the bellhousing than the pan if it's the rear main oil seal?

I thought of wiring a catch tray with a diaper in it under the bellhousing so I can drive it without a trail of oil following me but maybe it could suddenly get much worse.
. I took it off the road for now. It looks like I might need to pull the transmission or the engine. I dont have a lift or a garage to work in. Im dreading pulling the transmission to fix it but that may be what's needed. I dont own an engine lift, could rent one.

If it ever stops raining I'll put some paper under the car and let it run to see if I can see where it's dripping. If I'm pulling the trans Ill also do the output shaft seal.

Ive pulled engines out of automatics and Ive done clutch replacements requiring the manual trans be pulled. I know it can be a bit of a hassle to get things aligned with just blocks of wood on a rolling type of car jack and no transmission jack but it's possible. Im trying to determine if Ill have a lot of issues with that with this auto transmission. In particular the alignment and insertion. with the manuals I've made up a plastic alignment tool to help align the clutch but this does not have a clutch so maybe that tool is not necessary with an automatic?

I assume I might be best to drain the trans and the torque convertor before removing it, is draining the torque convertor necessary? I remember pulling a trans from a 140 and was a bit suprised when the torque convertor came off along with a huge dump of trans fluid from behind it.

Im wondering if maybe I can get a nearby shop to do the trans pulling and maybe take everything else off like the driveshaft and most of the bolts and linkage then having it towed in to do only the trans pull and replace. I dont really want to crawl in the dirt doing this but I can probably do it.. maybe that would only take a couple of hours of shop time that way and a shop could then help with the actual transmission pulling and replacement which is the hard part.

Ill check the pan bolts and the oil separator and clean the flame trap first, If I do find loose bolts then that might be a good thing but I'm suspecting the worst. I think a pan gasket failure might cause a drip but probably not a constant drip. Ive yet to determine if it leaks when not running but I think it is not leaking so much when parked, just lots under driving conditions.
