Nescomo,
 
I have always put in six full quarts and twelve ounces from another and have never seen the engine overfilled. The level on the dipstick is always between the "MIN" and "MAX'.
 
As to the CCVC, I believe it did fail. I have been driving for the past day or so with the oil filler cap loose and no oil has appeared around the CCVC. As to adding a Provent device, maybe later on. First I need to have the trans evaluated to see what is going on in there.
 
One question; is the CCVC available as an aftermarket part or is it still a dealer only part?

Do not forget to check your air filter for dirt.

I use a K&N air filter. Just cleaned it 4000 miles ago after 18000 miles of use. Was dirty but not outrageous so.

The dealer called me today and told me of two issues.
 
1. The oil leak was caused by a blown rear main seal. How the oil got on the top of the engine I will never know. It leaked around the CCVC.
 
2. Torque converter is toast and probably the front pump too. Had the F37 done in December of 2006. They replaced the TC at that time.
 
I am going to speak with the tech tomorrow PM. and see what else he has to say. I would like to retain that nice firm shift if possible.

Winter2,
Could you try to explain what "toast" means? Is it excessive wear of the clutch plates or destruction of the central element within the TC?
You had given the name of a company proposing a reinforced component that could handle the extra torque. Even if you change this component, the lockup clutch plates remain the same
 
I have to admit, 5 years ago my local Jeep tech understood well the latent problem of automatic shifting under high torque.

Winter K&N filters are not good for the CRD lab your oil and you will see the results. The main seal issue is because too much oil or the oil pressure is too high. Ebay sells CCV, go to the dealer is not too expensive. Use a normal filter and maybe your back seal leak will go away. Try it for two month.

Nescosmo, nescosmo
The torque converter unit and the set of clutches are two distinct parts of the transmission.
The first can typically become out of balance after overheating and the second should trigger a high oil temperature warning signal before the gearbox gets damaged.

How many miles (kilometers) did you have since the F37 to TC failure?
Are you going with stock parts or aftermarket?

I had the F37 done in December 2006 or about 23K miles ago. What is so funny is that the original TC was fine when they removed it.
 
As to parts, I am doing this under warranty (stock parts). Before the year is over, the trans gets the transgo kit. If the TC fails again, then I will put a Suncoast or other high performance part in.
