Well another issue. Its a 440 to a 727 (4x4) When I hit the gas before, at higher RPM it would make a sound like, a metal bladed fan was put against a sheet of metal (while spinning). But would quit if I let off. But now its doing it all the time even at idle. It is coming from where the transmission and engine meet. Its not the dust cover, it is tight. I know when both the tranny and engine were rebuilt something had been don't to the transmission to get it to work with the 440. I believe a shaft was to short or long. I'm going to have to pull it. But would like to know what I might be getting into.

sounds like the flex plate is broken. when the engine and trans was apart did they forget to put the aliment pins in? been down that road.

I am not a trans expert. This is just what I have learned about mopar trans over the last 40 years

On the older mopars the Trans would not go in reverse when the Trans oil filter was clogged, cold weather made this worse. Why rev. and not forward gears? Because rev. runs the trans. line pressure to 350 psi. forward gears to 100 200 psi. the higher pressure takes more volume of oil that the clogged filter can’t pass. but I don’t know about the newer trans. Also the older trans stops the lube line in park so in hot weather don’t sit idling in park. If your older mopar trans bangs real hard going straight to rev. try going to low with the lever, then go rev. it wont bang as hard. But it really needs a low/rev band adj. A trick to get longer life is to put rear end grease in a trans, one or two qts. Two works good in 727s. It will shift better to. I have used this trick on the older trans, 727, 904s with no bad effects. This may or may not work on newer trans. I have put one qt in my 99 Dakota v 6. about 8 mo ago, so far so good. A cooler is ALWAYS a good idea. I have had shift kits in two trans, I think they are good. Just don’t do full race kit on a street trans. I understand the newer trans have a check valve in the cooler lines. So if one of these trans blows up the check valve will hold junk and keep the fluid from lubing the trans. So the valve needs cleaned after a blowup.

 

What causes that high pitch noise is the throw out bearing not disengaging completely from the clutch. In fact the throw out bearing still touches the pressure plate release springs, allthough no force is applied to the clutch pedal.

What you do is simple:
Go back to the dealership and tell them to replace the clutch cable. That's the problem! The cable gets old over time and generates more friction than what the Ford engineers calculated for.

Hope it helps I just based it from my experience.
