Re: Trans early shift

Was this a sudden change or a gradual deterioration?

I’m thinking vacuum modulator.

2 ideas:

Pull the rubber hose off at the modulator. Any evidence of ATF confirms a failed diaphragm.

With hose disconnected, confirm full vacuum is available to the modulator.

Hope this helps.

Re: Timing marks. Want to add Pertronix

Timing marks were originally a series of “hash marks” stamped on the
harmonic balancer. Also included a few stamped numbers to indicate degrees.

My Pertronix unit seems to function just fine. I did switch to one of their
“Flamethrower” coils. Didn’t seem to make any difference.

My $0.02.

Re: Vibration at higher speeds

I’m not familiar with donuts between the shafts which you speak of, but mine is a ‘65. Wheels/tires are always a possibility. Old school says vibrations at lower speeds are caused by front wheels/tires and vibrations at higher speeds by rear wheels/tires. So if you swap wheels from front to rear and...

Re: modulator valve

Meaning no disrespect - are you sure it’s fuel, not ATF? Obviously, the modulator diaphragm has failed. This allows engine vacuum to (attempt) to draw ATF up the hose. Vacuum can’t draw enough to fill the hose, but fluid will sit in the bottom of the hose. How was it shifting? Was the modulator cont...

Re: Shifting Questions

For ‘65 with COM and 3.00:1 axle, shop

manual shows 1 to 2 shift (at minimum throttle)

should occur 8 - 11 mph.

Re: does vacuum advance really help ?

I predict that you’ll get a variety of opinions on this. Mine goes like this: vacuum advance functions as a measure of throttle setting, which is then used to extend burn time (advance) or delay (retarded). Following that line of reasoning, I use manifold (not ported) vacuum; i.e.: let’s tell the di...

question - COM downshift hardware

Per figure 47 (group 7) of shop manual, I understand that the downshift shaft and (external) lever

are retained by internal nut. This leads me to believe that shaft and (external) lever are one piece.

Can someone confirm this? Or does the external lever separate from the shaft? Thanks in advance.

Re: 1964 Power Steering Query.

As mentioned in 2 previous posts, adjustment of worm to rack preload

may be in order. Shop manual outlines procedure; section 2 of group 3.

Not a common adjustment, but not difficult.

Might be worth a try before getting into heavy, expensive efforts.

Re: Vacuum questions, rear vent 1965 T-Bird.

Yes, the function of that little block with screw is to slow the closing of the rear vents. Manual calls for 70 seconds delay. Hope this helps.

Re: Points or Electronic Ignition

(for methos)

Pertronix installation instructions suggest switched 12 volt source to coil.
Note - source voltage.

This involves bypassing the resistance lead to coil which Ford built in for us.

Hope this helps.

Re: 1964 Thunderbird - Its time for timing

FWIW -

I’m at 10^ initial; stock flyweights; lighter springs and manifold vacuum.
Engine seems happy, so I’m happy.

Re: Neutral Safety Switch Question

I fear I have provided incorrect information here. Bob C. is correct. Owner’s Manual speaks of transmission selector (to be in Park), NOT the position of swing-away wheel/column.
