Adrian:

Not familiar with flatomatic, but have torn apart several ford automatics.  Sounds to me like very low oil level or something in the torque converter isn't getting pressure to the connection.  The C4 is generally pretty rugged.  If you are adventuresome, get a later model with more gears and adapt to open drive line or fab a torque tube adapter.

No power is a very general term. It could be transmission or engine related.

 

Does the engine rev up nicely and sound strong with no missing? Have you checked the compression on the engine? Does the engine have good spark?

 

Does the transmission go through all of the gears or does it shift sluggishly?

 

How quickly does the car go from 0 mph to 40 mph? Does the engine seem to race like a slipping clutch when you accelerate?

hi both

the engine has been overhauled and all is ok

yes it does/ race

engine seem to race like a slipping clutch when you accelerate

speed 0 to 40 forever

will do 18 in first 

40 in second

but only 50 in 3 rd

revving its heart out in all gears

also have to drive it like a manual

wont play in drive

best example took car for a tracking steering check

would not go on ramp

engine revving no torque / power to go on ramp ??

crawled in the end on ramp

oil level  correct running in park e.t.c.

Curious as to what rear axle your using. ?

[adyv8]

hi

I have had the axle overhauled

and a open drive kit fitted

speedway crown wheel and pinion

3.54

no overdrive

thanks ady

Your engine may not be providing the correct vacuum for the modulator. Is the hose connection at the modulator the same diameter as the engine port? The fluid level should be checked with the shift lever in Drive and the transmission at operating temperature.

 

Here is a link to a trouble shooting guide for the C4 transmission.

Sounds like something not correct with the transmission.  Fluid level, slipping , bad torque converter .   

[peecher]

Sounds like one of two things could be wrong: either the one way stator clutch in the torque convertor is bad/slipping or the main forward clutch in the transmission is slipping. If the slipping is present in Reverse I suspect the problem is in the torque convertor.
