Clunking Niose From Ford T5 Trans/Clutch

Last year I converted my 1966 Mustang C4 Auto to a brand new T5 trans and all new parts including cable clutch operation.

Since the 1st time I drove it, it has made a clunking or back lashing noise at very low speed, maybe 1 mph.

I mean when I let out the clutch, either in 1st or reverse, it clunks and jerks the car, then goes away as I speed up.

It gets really clunky if I let out the clutch and press it right back again. It like bangs back and forth.

No, don't laugh, it's not that kind of jerking.....I know how to drive a stick......

If I hole shot the car at about 2000 grand and power shifting, no problems what so ever.

Works great when I put it under a normal take off load and continue to normal shifting & just cruising.

Another example: Say I am at a red traffic light. Cars in front of me, and people are getting ready for the green light, so everyone starts moving just a little. I have to let out and push in the clutch until the traffic light changes & I starts rolling normal.

It's that pushing in and letting out the clutch is when the damn thing starts its clunking/jerking noises.

At first, I thought it might be a defective pilot bearing, in that it might be the wrong size and the trans output shaft could be smaller.

I didn't test fit when I was installing. Is that possible? It is a roller bearing type.

The clutch setup is an off brand that I bought off Ebay. It is supposed to be the "Cobra Clutch" 10 1/2" setup. Which does measure at 10.5"

There doesn't seem to be any slippage of the clutch or burning smell. Although there is vibration at the higher RPM range, 3000 to 4000 RPM. But I just think it's the beast in the car. lol

The noise is coming from the front of trans & clutch area. At least that's what it sounds like inside the car.

When I converted to this setup, I had the drive shaft shortened about 2" and with new joints.

Give me some ideas on what might be the problem.

I'm hoping it's not the new trans that I bought from Ford as they said no warranty.

The trans does have the 93 T5 Cobra specs.....

That goes like this..a dab of lash in the gears. a dab of lash in the driveshaft yoke, a wee bit of lash in the u-joints, some gear lash in the 3rd member and so on and now you get the low speed clunk you are referring to..Dunno what to tell you other than to check it all out. Could be as well you are lugging the engine a bit at a low rpm which can cause a clunky jerky action..Key point is that you are saying that a normal start with a bit more revs and it is all good..

I have tried most all of it and now do what is known to work..

I don't know.....I just know I never had a manual trans do this before.

I've checked and rechecked all of the exterior drive line. Everything is as should be.

Never made this noise until I converted this over to the T5. I just don't think this is normal.

Even when I took the car for an alignment, the mechanic told me something was not right when he took it for a test run. He said that I should get it checked out.

I'll try and get a video uploaded with the noise......
