clutch/tranny

horsesnake95 · 12-29-2002, 05:49 PM

Hey guys.... I have a 95 GTS and had the tranny rebuilt a few months ago. Also have a BBK quadrant, firewall adjuster, and adjustable clutch cable and a kevlar clutch and pressure plate from NAPA. I have to use alot of effort to get the clutch pedal down and have all kinds of problems getting the tranny into any gear most of the time..... Lots of stiffness in the clutch pedal. I've tried adjusting eveything repeatedly to no avail and any input you guys can give would be awesome.

i dont know why but i have had to replace my clutch cable every other month, mine too would get really hard to push down. but every once in a while it would get easy. when i would change the cable it made a world of difference. (some people said that i might not have it routed right) also the bearing retainer that the throwout bearing slides on might just need some lube, it can rust without any oil and cause the bearing to bind up on the shaft when you push the clutch in.

Yea, SN95 that happened to my son's 96GT, the throwout bearing was running dry on the input shaft bearing retainer and making a creaking noise. We greased it with a piece of string.
My other son has an aftermarket clutch quadrant but stock clutch and he has higher than normal pedal effort. The ratio must be higher on those aftermarket quadrants.

Sounds like you are getting some firewall flex, and the clutch is not totally dis-engaging every time you shift.

There are firewall stabilizer kits, or you can fab up some support plates if you are gifted that way.

The throwout bearing can bind on the bearing retainer. The Aluminum retainers can develop grooves where the throwout rides. Switching to a steel retainer can cure this.

Problems with the alignment of the trans and /or bellhousing esp if an aftermarket bellhousing was used can also cause binding of the throwout bearing. The center of the bellhousing hole has to be in line with the crank centerline.

Problems with the clutch fork or pivot ball can cause binding.

I still think it's an overly stiff clutch causing firewall flex, and incomplete disengagment
