I read a thread about trans fluid leak @ converter,.. and I was going to reply, but since I don't know know nothing about anything... I didn't want to start a range war with the GOB's...but...if you have a trans leak after the cars been sitting, come out to a big puddle under the car...It's most likely, hardly ever. not the converter.... what happens is when the car sits the fluid burps out of the converter, and over fills the pan... now... I'm gonna say, 99 out of 100 times on hot rods.... it's the lo-car trans fill/dip stick tube... and it usually not the O rings... but the connection on the braded line... most of the time people over tighten with the 2 1'' wrenches... and some times it's just loose there...I know you are not susposed to have to,... but I use a sealer and put it back together and it quits... and yes this is the cheep ass way I do it at my shop to save people from having to buy a bunch of new stuff,.. or paying 4 or 5 hrs shop time to fab a new tube...
We need to let the cars run regularly. Better yet drive them weekly. But turbo 350 leaks at the fill tube detent cable speedo bullet and shift shaft. Pan gasket lots of time over tightened are the washer head fasteners are change to bolts and lock washers. Right now mine is good cause the trans guy checked an repaired all theses.
agreed most the time all the others things are done.... then it still leaks.... most don't check the lo-car braided steel line... I've learned to check that first.... and like said... most the time it's not the o rings.... it's the connection to the braided line...
My 40 coupe with a 350 trans if not started and driven regularly leaves a puddle that looks like a quart but in reality is not a lot. Converter drain back is all we can figure. I've had it checked several times and that's the conclusion the repair shop has come to. Have no similar problems with my daily driver deuce pickup with a 350 trans. Also nothing to date under my deuce sedan with a 700R4. I also have Lokar cables in my 3 auto trans hotrods. They look cool and are easy to install but in reality can be a problem.
if you keep an eye on it, and see where it first starts coming out, will help the fix...where the locars leak is the fitting above the 2 o rings in the trans... most trans shops replace the 2 o rings... then when the converter burps the fluid , it raises the level in the pan , and starts leaking... some times you can get 2 1'' wrenches at tighten the fitting, but most of the time some one has already over tightened the fitting... but like said, I just take the fitting apart,... clean it good and put sealer and never had one leak again...
Why don'cha drain a little trans fluid outta the pan ...see if that solves the puk'in problem. (Maybe a cup full shouldn't 'destroy' the tranny)..... It would solve the leak problem when parked. 6sally6
Wonder if the cooler is draining back for some reason. The converter and cooler might be that much too much. Possibly swapping lines on the cooler would cure it...?
I have had Folks leave there cars in the garage for months on end, left a puddle of trans fluid on the floor Most were wealthy Taiwanes .... most drove Lincolns with 460's with a C6 I was best friends with one of their Sons and they would call me when they had problems cause the repair shops would cheat them .. the convertor would settle on the seal after so long and it would cause a drip I would check the fluid to make sure it was only low, add a bit and start the car up After running a while, I told them to start the car and drive it a few miles every 2 or 3 weeks The leaks did stop This is just my experience and trying to add a bit of help A bit of trivial, they called their Friends and I had more work than I could handle Was invited into their homes and such, they liked me enough to warn me where the Tong lived and to avoid that Hood Ricky
what will happen is when you drive it will be way low on trans fluid...it's how it works....when it sits the pan over fills from the fluid in the converter...and when it starts it fills the converter back up.... when the converter burps the fluid out, it over fills the pan... the seals retain it till it starts again.. it leaks other places like said... the locar braided line has a hard plastic liner , my guess is so that pulling the dip stick in and out it slides easier ... the fitting is a squish and if over tightened it leaks,,,.. and then when you re-tighten it, it stops it for a bit, then starts leaking a bit.... that's why I use a sealer there...then it can't leak... any way.... like I said i've learned to check there first if I see a locar tube..
Sounds like a good place for an over-sized racing tran$mi$$ion fluid pan. No kidd'in..........an external trans cooler might be big enough to act as an accumulator... 6sally6
