After the "what is that liquid on the floor?" and applying the white paper towel, noted a tiny leak on my '87 auto tranny. The '87 auto tranny that I removed and had rebuilt about...12 months ago.
Initial glance, at least it wasn't the pan or the shifter, likely further back. So, today, hopped out of bed at 6 AM and started chasing. I dreaded the real oil seal (not the engine's) was leaking, due to something I failed to do. But, after removing half the exhaust and looking (while side jacked!), I can't fathom where the leak is...the speed sensor? But, it's not wet at all. Both sides of the extension case are dry too. ?!
I already dread the idea of just starting Her up and waiting for a drip, how bad is that with just the headers?? Besides the super loud part.
Opinions from pics?
Nothing touched, sat overnight. Pan was nice, dry and clean all the way round (thank the Maker, I do NOT want to change that seal and filter for the 7th time!).
Front edge of the extension case is dry, all the way around.
Side is dry.
The beam bolts certainly dripped on the bracket, but only the one side. Rear seal is dry. The bottom of beam had a slight film further back, foot worth or so.
Wiped the case right under the speedo sensor, little wet and dirty as expected. But nothing above the lip nor "in".
Other than the red drops, pretty clean considering. I like to Drive a bit.
Have you checked the oil level for 'over full'? How much have you driven it since the install? Could you have gotten it hotter than since the install for the first time and the 'over-full' vented out the case vent? The vent is on the top of the case. It usually runs off the sides and forward, but could end up on the beam bolts.
Another possibility which I had on an 88 project car but it doesn't look like your rear seal is leaking. If the beam bolts are overtightened, the tail housing gets distorted, the bushing gets loose, migrates rearward into the seal and causes a leak. You might check the beam bolt torque while the exhaust is out of the way.
There's a couple of ideas. Neither likely, but would show up on the beam bolts. Cheers.
700R4 Tranny Leak.....Where?!
Besides the super loud part.
