Ron,
Book calls for TCH fluid. I do not know what difference there is between the TDH and TCH fluids, I've been meaning to check into it. I'm sure others on the forum can help with that. I have an old CK which has that buzzing sound for a minute every cool morning, and after having resealing the shuttle, it was really bugging me. So I changed the shuttle oil I have always used (TDH), it's cheap, and put in ATF. Someone else had done this on the forum, to help alleviate sluggishness, when cold outside, as all BCK's are known for.
I suppose the oil is about a 75/25 mix now, as I could not drain the converter. Great to try this on your own machine, anyway it worked, stopped the buzzing, so I think the change in viscosity may have helped. I had previously replaced the 2 seals under the shuttle pump with large o-rings from my metric kit. The correct sealing rings from Case are no longer available, they look like garden hose washers. I likely will never find out where the air leak was. One thing to check on these machines is the routing of the steel lines, along the hood and past the radiator, great place to rub and vibrate. Phil
