As I back down my driveway I start hearing a noise kind of like air squealing from a balloon (but not as loud). It does not start right away just after I begin the downhill slope of my driveway at this point I have a foot on the brake. It stops when I shift out of reverse.

I'd check the transmission fluid level first. Since you had an effect on the incline, I'd start there. -
Found the cause. after installing a new bellcrank assembly the car was making these squealing sound in all gears including park. I was able to make it stop by adjusting the transmission kickdown rod to the bell crank assembly.
But it seems as it now takes the tranny longer to shift in to 3rd. could this be related to the the rod adjustments? I know the manual has you puting the car on a lift, hooking up a pressure gauge to the the tranny and a tach to the engine and adjusting idle speeds and the rod lenghts with the car in gear. so I hope I havn't caused a new problem by adjusting that rod length to make it stop squealing. If anyone has any insight into this I would love to hear about it Thanks, EricYellow98Cobra

Yes, as the 58/60 COM used TV (Throttle Valve) Rod actuation instead of modulator valve (61/ ).
The adjustment has to be exact.
SOME applications (BIRD included) had a test port under the hood (has been discussed here). You may be able to use this port for the pressure gauge if you can find a suitable transition fitting (never supplied by FOMOCO).
If there is a shortcut (there is for the AOD), I am not aware of it.Comment

thanks, I am going to have someone look at that for me. The car ran ok on Saturday. Went I start it today and I had hard time getting it to start it idled really poor, back fired a couple times I drove it around the block and the accelerator would not back down, got it back in the garage and shut it down opened it up and removed the aircleaner went start it back up it did not want to start I pumped it a couple of times and it backfired and caught on fire for a minute. I let it rest for awhile it started up but wants to idle high, if I push on the rod I can calm it down.

Yes the bell crank I replaced the old that had a lot of wobble with one that has just a little wobble and it changed the tension on the linkage rods. if add tension on the return spring it will help but now it doesnt want maintian a good low idle?Yellow98Cobra

The linkage should always go back to idle. If it is not, you have something causing binding perhaps, or could be the choke hanging on fast idle.
As far as pressure, I think it is adjusted too low and you are getting excessive slippage either in the clutches or friction/disc plates. Continuing to operate with slippage will cause them to burn and you'll end up doing another rebuild. The pressure needs to be increasing immediately off idle as specified in the manual.
I'd get the transmission somewhere were you can adjust the pressure as specified in the manual.
Getting the bellcrank, throttle, and transmission lever all adjusted properly will make a world of difference with the driveability of the car.Comment

Does anyone have a MPC which will show the blow-up Ill (Fuel Linkage AT)?
BTW- The factory assembly check port is directly behind the bell-crank. My understanding is that this was used only on the assembly line and not in the field. FORD never released a fitting to fit a pressure gauge. One should be able to find something that will work though.

here is a blow up i found i have the 2 springs that it shows
I believe you are missing 1 of 2 retracting springs (Basic PN 9736). I thought I had a detailed photo but cannot find it.

Yes I already have printed the picture from that thread it is to bad the one with test equipment hooked up is missing.
I found the photo(s)...

Oh...OK... I didn't see it.
You need to determine where the binding is. Maybe remove the throttle and trans hookup and be sure the bell-crank moves freely (lubricate shaft where it rides in bracket). Then hook up accelerator rod and determine same. Disconnect throttle rod and reconnect trans linkage. Check for binding.
Hook both back up and see if there is binding. It may be the throttle rod needs adjustment. The carb returns to proper idle with the rod removed?Comment
