Hi I really need help getting this vehicle back working.

I was diving and the temp guage started going up.

I opened the hood and rad cap. Tranny oil sludge mixed with coolant overflowed. Sludge went all inside the overflow too.

It is also mixed in the Tranny. Still drives but heats up.

I changed the Transmission oil cooler, flushed rad, and flushed tranny.

Drove it and after 10mins it keeps heating up. Some more sludge came out but just a little compared to 4ltrs from before. No Sludge in the overflow tank.

I keep hearing pressusre build up in rad and hoses or in the engine. Bubbling sound.

I am wondering if the thermostat is plugged.

Anyone knows the fix.

Buy the way engine oil is still clean.

Thanks.

 

Attached image is very helpful here. Thanks a lot.

 

Everything is fine now. It just had air in the system after I flushed everthing.

Thanks you for your help.
