I recently swapped out my C4 transmission for the T-5. The installation went relatively well until I went to drive the car. I backed it out of the garage no problem but when I shifted into first and started off the car would accelerate but not at the same rate the engine did. It seems like teh power is not being transmitted to the rear wheels. The clutch is a brand new ZOOM set as well as a new ford racing flywheel, a Ron Morris clutch cable and a rebuilt T-5. Anyone got any ideas?

 

Sure sounds like a slipping clutch. Is it adjusted properly?

 

Sound like you have a ton of preload on it...I assume the ZOOM is a modern clutch that requires preload.

Are you using cable or hydraulic linkage?

WHAT clutch linkage set up did you use??? and what bellhousing??

 

He said he has a cable. Does it have the firewall adjuster?

 

I see it now...Its probably not properly adjusted and adding excess pressure even at rest.

I am using a ron morris clutch cable. It has an adjuster at the firewall but I have adjusted it in and out and it doesn't make any difference. The bellhousing is from the 93 t-5.

 

when you adjust it you need to watch what the clutch fork is doing.

Mark the location of the clutch fork against the bell housing hole. Make a mark so the edge of the clutch fork is inline with that mark.

Do whatever it is you need to do to release the pressure from the cable...Undo it from the clutch pedal if you need to...We want total slack in the cable.

Now go and look at the mark has the clutch fork move?

Grab the clutch fork and wiggle it front and back (same axis as the cable would pull it) The clutch fork should wiggle about 1/4" or so...(or it should move quite a bit as its free now)

Now move the clutch fork so it presses the throwout bearing against the clutch fingers if it has moved from its original mark, mark the new location. Reattach the cable so it does not move from that new mark. then adjust all the slack out of the clutch fork so you cant wiggle it anymore. Try that.

If it has not moved from the first mark you made and you can wiggle it...You may have installed the clutch disc backwards...It will not work right if its in backwards not sure what it would do but I would guess it would make a really nasty sound and work like crap.
