C4 transmission notice small leaks above pan is this serious ?
There's small leak just
above the pan area is by
a connection line that
goes up towards engine
driver side ? Can I just
seal it with silicone.
Cooling lines. Need tightened or clamps may be loose if rubber lines
No on the silicone trans fluid is caustic (disoves cheap rubber) lines are under pressure and can be repaired one of two ways compression fitting or line replacement
ford pans rust thru easily! if that's your problem yes a patch can hold pan pressure , J B weld,a glue of sort will for some time!
First of all, is it actually leaking (wet and dripping) or just damp? If it isn't dripping leave it alone. If it is, follow tommcmanis advice.
if it is the gasket, use the leak as an excuse to service the transmission. The gasket is changed as part of changing the filter. It is not difficult nor expensive. If it is the cooling line, it is a simple double flare fitting. Check the entire length of the line. If it is good, try tightening the retaining nut. If the line is rusting near the transmission, but the rest is good, you can cut our the bad part and use compression fittings to connect the old to the new. Changing the entire length is not difficult, either. One important thing. When topping up or refilling, be sure to use Type F transmission fluid. Mercon is NOT a replacement for it. If your Ford is old enough to have a C-4, you have recirculating ball steering. Always use Type F transmission fluid in our power steering. That is what Ford specifies.
Yes I changed the gasket already from the pan.. So I may have to tighten those nuts from above lol. Its small drips nothing major once I changed the gasket. Also if there's oil coming from small drips from between the meet of the tranny and engine is this a major problem ... I'm noticing some small oil leaks by my straight 6 engine.
Trans fluid from inside the bell housing? Yeah, that could be a major problem. Either the Front Pump Seal is about to give up the ghost or there's a pinhole in the Torque Converter. (Pin holes are rare and Front Pump Seals usually blow out all at once but, who knows?) Not trying to scare you here but any fluid leak from inside the Bell Housing will require the removal of the Transmission to access. If your new Trans Pan Gasket was cork, it will require a re-torque after 15-20 minutes - Neoprene or straight silicone, not so.
This transmission is an easy out, be sure to replace rear main oil seal at the same time. Three click the coverter before tightening any bell housing bolts.
