94 Mustang GT Modded By Chimps


I have a grocery list of problems with a 94' GT with a 5 speed. I was told that it has a zoom kevlar racing clutch. At 2,500 rpm there is a very noticeable vibration. Above or below is smooth. Also the speedo is off by 7 mph. When the speedo reads 70 mph there is such a crazy palpable and audible vibration that I just pull it into neutral and coast until it goes away.
It will grind at times going into 2nd and 5th. It has popped out of gear in 5th many times. Suspecting clutch and flywheel. Thanks for any help.

the gears grinding could be a clutch issue, the popping out of fifth gear would almost make me think tranny internal problem, but then again if your clutch is out of wack you may not be going into gear completely. one thing i would try is once your in fifth gear, without touching the clutch let off the accelerator and pull the shifter down as if trying to slide it into gear. take not as to if it seems to completly slide int o gear and afer your do so note as to weather it pops out of gear after doing this.. if its a brand new clutch it could be grabbing alot. even when shifting. i had this problem on my cummings when i put a heavy towing clutch in. grabbed way more than it should have when shifting, did this for anout 2k miles till it wore itself in. then never had the problem again. you could also have a broken spring on the clutch...

Thanks guys! Also if I go for a high RPM launch...it will slip as though it is not even in gear.
I have to do a rolling launch or it slips terribly. Not sure if too much motor for the clutch/tranny or just another incompetent mod from the previous owner. Car is referred to as a "home made" car by a technician buddy of mine. LOL!

Also, at speed between 65 and 75 will get tremendous vibration that shakes entire car and shifter shakes so hard that you can hear it rattle in the opening of for the tranny. Below 65-75 and is very smooth as if nothing wrong. Also get weak vibration at exactly 2500 RPM.
Will try to get pics up soon so everyone can get a good laugh. Previous owner painted it yellow. Looks like a hi-liter!

Vibration at certain rpm can be as simple as u joints. You have to remove the driveshaft to check. It's not just a 'wiggle it and it feels good' thing.

^^^^This.
The chimps that modded my car snapped two bolts off in the rear end yolk for the drive shaft. had to get those out, and get new ones since the TWO LEFT INSIDE OF IT BROKE. two left. inside of it. 4 bolts should go in there. That said, I had to replace the worn ass ujoints as well. Vibration isn't so bad(the shaft itself is a little dinged up from the chimps)

I get some pretty good vibration too, but that's because this tko tranny isn't mounted right. when we took the motor out to try and fix a knock along with a very very gone clutch( said chimps really fucked this car up) we had to jack it up. it's a "Custom" fabricated mount, and I didn't mount it right.

I really hate having to fix problems that a prior owner created due to stupidity.

Drive shaft and U joints have been replaced. Still have the same shuttering/vibration at 65-75 Mph. Have not had driveshaft checked to see if it is balanced. Nothing changed from the swap of the U joints and shaft though. Very much looking strongly at clutch and tranny internals.

This sounds like the problem and you will probably find other stuff messed up while you're working on it. I am SO glad mine was stock when I bought it. I hate fixing other peoples half assed jobs.
