Hi Guys,
please give me advice. If I drive with my truck (6.0 diesel), my tranny fluid is disappear from my tranny. No leaks, tranny, engine, cooler absolutely dry.
Maybe Copperfield makes me any practical joke?
By old Mercedes cars over the vacuum pipes sucket out the engine from the tranny the fluid.
Thank you for helping me, I need quick reply. Here in Europe I can not find specialist for my Amys

 

If it isnt dripping on the ground the only other place it could go is into the engine radiator.

 

Dear Mark, thank you for reply! That was the first problem in my truck, after replace a new radiator, tranny fluid was in engine coolant and coolant was in ATF. After this problem I flush the engine and tranny. I pulled out the two pipes from the radiator and shorted each other with a rubber tube. Since them every 600 miles cost 1 liter ATF fluid.
Sorry for my poor English. Thank you for your kind attention! Sandor Soos from Hungary

 

Sandor, is the truck four wheel drive? Fluid could leak into the transfer case.

 

Yes, it is four wheel drive. Tomorrow (here is 21.56 hour in the evening) I will check the transfer case, till now I am alltogether over 4 liter ATF.
Thank you and tomorrow I will send you a mail about this case.

 

Is the T case open to the transmission on this set up?

 

No, there is a seal between them. If the seal fails fluid will migrate from the trans to the transfer case.

 

My 03 F150 would loose a litre every oil change into the transfer case. I would drain the over full t case and add to the tranny every time. Good way to flush the transfer case.

 

Thank you for advices! Today we check the transfer case and the oil was ok, till the higher screw. Till now, three car mechaniker took a look to my car and no any result. The last said me, i am dreaming or drinking...
Another question: since coolant was in tranny, the shifting is not the same like before. The mechanikers said me, i should overhaul the tranny. Where can i order the cheapest parts for my truck? I must calculate the price of USA and plus in Europe 12 % customs, plus 27 % VAT in Hungary and the shipping. It takes together 100% of the price in USA.
Thank you for the help!
