Someone explain? Auto transmission

So I have a 88 yj with 4.2 and automatic trany. I'm wheelin today and cross through some deep water ( up to the top of the wheels and I have 35s and a a lift so its pretty deep! ) it goes through it like nothin then about 5 min later there's redish pink fluid all over the trail and I've got no movement and end up getting towed. But here's what I don't understand all the fluid leaked out within a few min and from the front kinda near the radiator not near the trany. So does anyone know what happened? I'm kinda ne to jeeps and a little confused.

If it was coming from the radiator area, it was probably the trans fluid cooler(if you have one ). It looks like a small radiator probably in front of actual radiator. Check it for holes or loose/broken lines. GL

I'd been driving for bout an hour but the jeep wasn't very hot and the water was definently way colder but not extremely cold so that could have done it but ill check the lines.

Ok so I checked the lines and didn't see anything obvious (the lines run out of the driver side of the transmission and up to the radiator correct?) but I did see that the plate thing between the transmission and the engine is cracked anyone know if this could have contributed?

There is your problem!! Your transmission has come unbolted from your engine. And you probably lost transmission fluid out of the torque converter. Don't drive it till you get this repaired great damage will be done.

I don't think your trans is unbolted. You are however missing the flywheel inspection cover/dust shield. There is no indication of a leak a where? Fluid on the frame/under body is easy to spot

I agree with redneck. Doesn't look unbolted to me either. If you're leaking near the front of the Jeep it's either a cooling line or trans cooler itself that is damaged. Easy way to tell is wash real good let it dry put some fluid in it and crank it up. The pressure will push it out. Fluid is bright red you'll see it

No I know the trans is still bolted up just the dust shield is cracked and broken off, can it be replaced with out removing the trans from the engine. I did find the culpurate to the leak, a line up front busted so while all the fluid was out I changed the filter and hopefully when I fill it back up everything functions properly.

No need to remove trans to replace shield. Maybe starter but not trans
