Trans fluid drops out of the dust cover weep hole?
 

I am still chasing a small leak that is only 1-2 drops a week after driving.

I think I may have narrowed down the source of my small leak. During my last oil change I didn’t add UV dye to the engine oil, but there was still dye in the transmission fluid. I’m seeing some green residue and wetness around the transmission pan. What I don’t understand is how transmission fluid could make its way from the pan area into the dust shield and then drip out of the weep hole. Is there a path where fluid could migrate like that? The flywheel is dry and it isn't slinging fluid and I think if it was the front pump seal it would be a lot more fluid.

Your pump is most likely leaking, the converter is possible but much less likely from my experience any way. It could be leaking when it’s cold and not enough to make a big mess. There’s really no other path for the fluid to get from the pan to the dust cover.

Pump to case seal, pump to case bolts, pump to TC seal. Any minor weeping from one of those areas. Will not make it far forward enough to be flung off of the flexplate.

^ and a couple of drops a week aren't worth the expense. My selector shaft seal leaks enough that I'm going to have to bite the bullet and have it fixed. Arthritis has me quite limited, so I can't do it myself.

I think I am going to try a paper towel test and shove some up in there after a drive and cleaning to try to catch the source instead of the fluid leak end destination. I am really hoping it might be the front of the trans pan seal leaking into the dust shield when the fluid drains back into the pan

I might add some high mileage ATF to maybe buy some time and then live with it for now.

A complete seal kit installed was quoted to me at $1200 from a local transmission shop.

You might as well rebuild it if you’ve got it out and aren’t 100% sure of its history… just my .02 anyway.

Check the vent is clear.

Just for reference. Last year a local shop rebuilt my th350 for under 2K including new converter some small upgrades. No race parts. Very happy with results. I removed and installed. If it's out to reseal, may as well go all the way. Happy with my results. Shifts like new. Zero leaks.

I had my 350 rebuilt for that with a rebuilt converter I R&R’d the trans not the shop so no labor .

Same here. I had the one rebuilt in the wife's 72. Cost me $1136. I was originally going to have them do the entire job. They told me they could rebuild the transmission in 3 days, but it would be 6 weeks if they did the R&R. They had it done in two days.

A lot of Transmission shops won't warranty your labor or your cooler.

Check the trans selector shaft. I had a similar problem on my 06 GTO where it would drip a few drops from the inspection cover but everything inside was dry.

Re: Trans fluid drops out of the dust cover weep hole?
 

The source seems to be running down the the inside passenger edge of the dust cover. I need to look at the flywheel closer. I agree if I have it out i might as well have it rebuilt. The shop I had it quoted gives a three year warranty.

An XJ guy I follow stopped warrantying his rebuilt trannies because people would mangle the cooler lines removing/installing and cook them. Still stands behind the ones he installs

Would a new torque converter help it be more responsive or hook up quicker or a new converter with different specs

Re: Trans fluid drops out of the dust cover weep hole?
 

Short answer is yes, but there’s a lot of variables there and truly probably not worth pursing unless you go thru the engine, especially the cam and heads to be able to get the most of a higher stall converter. Higher Stall speed will change the driving characteristics quite a bit. They are fun to drive like that though.

Mine did , he even gave me a can of the flush they use for the cooler . Only thing I had to do was bring it to his shop afterwards for him to look at the install and test drive . He does a lot of older vehicles . Going to have him rebuild my Studebaker’s Borg-Warner trans not the it’s bad but it starts in 2 nd gear which is factory even though you can manually drop it into first . Just the way they were made . He converts it to a true automatic three speed .

Can't believe today's prices. Of course, I'm livin' in the past! But even back in 2015, a friend of mine rebuilt a TH350 I had using about $100 in parts. The trans was out of the truck when I took it to him, and he spent around 2-3 hours going through it. I then added a $50 TransGo kit to the valve body, and bought a reman converter for $60 from TranStar.

I'd guess parts must cost 2x as much now, and labor is $300/hr.
