What can cause those leak

It could be any number of things, but one thing that comes to mind, is the cam sensor seal.

First verify if it's an engine leak or transmission leak. Which one is low on oil? Check trans by turning tires to right and pulling plug above driver's side axle and seeing if oil is to bottom of the hole.

And brake fluid too. Can be leak from master cylinder area.

I recently had my clutch replaced and I believe it is tranny fluid leaking but I can't find where it is leaking from

Well unless the case was separated, changing the clutch normally wouldn't cause it to seep from the mating surfaces.

Get a paper towel and soak up where it is leaving a drop suspended to see what color it is.

Looks to be a 2000, so it would (hopefully) look like relatively clean engine oil if the factory MTX fluid is still in there.

Were the axle seals replaced when the clutch was done? It would take some turbulent air to get the oil that far, but it is not impossible.

Other than that, the previous suggestions are good places to check.

That'd be a lot of oil coming from the trans if there's no crack. Sitting there, no oil is up top. It's all sitting in bottom half of trans.Check fluid levels and see which one Iis low. Engine oil, trans fluis, brake fluid. Clean it off with brake clean and paper towels, and go from there.

Isn't there a vent on the top that will puke out fluid if you overfill the trans?

Hopefully it's not the rear main seal, but I think the clutch would be slipping if that was the case.

If you over fill it will leak out the fill hole which is lower than the top of the tranny.

Found where the leak is after driving it for a while and quickly checking under the hood. Bubbles and trans seemed to be coming out of where its circled

Could probably be spewing while driving?

If there are air bubbles, it is not venting properly. Thermal expansion will create pressure and force the oil out.

I had a problem axle seal leak on my '92 Sundance Duster that they kept having to repair under warranty. A change of Service Manager that actually looked at technical service bulletins cured the problem: They neglected to put a vent in the MTX.

Fixing the vent may help 95%, but it may still seep a bit as the oil will sling around in there while moving.

After the vent is fixed, you may get away with scrubbing the area and using brake clean to degrease it good, and smearing some RTV on the location.

Otherwise you would have to pull the MTX, and separate the case halves, install diff saver tabs while you are there, and clean it up, get a tube of anaerobic sealant to seal the halves and reassemble.

The vent is the part with the loose fitting cap just forward of the shift selector shafts.

If it is clogged with gunk, it can hold enough pressure to create leaks.

The cap was missing on our ATX, so I just ran a tube up to the brake booster to keep it high enough so water couldn't get in.

It is a 1/8 pipe thread, if you need to get a barbed nipple to replace it. Just slip some tubing onto the nipple and route it to higher ground. One less worry if you get into a deep puddle.

Unless you're filling it through the reverse light sensor hole, which is much easier. Just gotta remember to pull the plug on the fill hole so you know when it's full.

You can do this but I will never again. Had nothing but problems for 2 months with the reveres light switch. Funnel with a hose is the way to go. If you want to get fancy one with a shutoff valve
