There is a video about this on line

I would suggest that you get a paperback repair manual like a Haynes to help you if you do it yourself. Or sign up at Autozone.com and see if they have any downloadable free guides specific to XBs. Autozone won't spam you for signing up.

the problem may have been in the damper spring setup in the clutch plate
it the clutch plate was a standard plate , it would have had 4 damper coil springs but the last plate fitted may have been a heavy duty plate that would have had 5 or 6 damper springs
if the springs are of insufficient tension then there is a grabbing action during clutch engagement but with more springs and different tensions that is overcome and the action is a smooth clutch application
manufacturers that have design faults quickly change the design as clutch shops are fussy when it comes to rework so I would think that it is not the clutch but an incorrect plate for the application

Disconnect the battery. Drain the primary oil and remove the outer primary cover. Remove the four bolts that hold the clutch spring in. Remove the clutch spring and pressure plate. Then, you can remove the friction and steel plates. If you want to remove the entire clutch assembly, you'll have to remove the nut from the transmission mainshaft and remove the sprocket shaft nut. The mainshaft nut that holds the clutch assembly on has LEFT-HANDED THREADS. Once you get the nut off, you'll need a clutch puller to get the clutch assembly off the tapered transmission mainshaft. Get one of the pullers that screw onto the mainshaft and you rap it with a hammer. You do not have to disassemble the clutch assembly completely to remove it from the mainshaft. You can take it off as a unit by removing the snap ring in the center and removing the adjuster plate. Remove the sprocket shaft nut, the chain adjuster nut, and the mainshaft nut and remove the engine sprocket, primary chain and clutch assembly all together.

Good Luck

Broken linkage, or the clutch itself has failed.

autozone.com sign up its free then click on repair guides .... drive train....transaxle.....then manual trasaxle....then clutch it will give you the assembly and the torque ratio for your flywheel bolts

1. 1 Remove the fan and clutch assembly from the fan's pulley. The assembly attaches to the pulley with several bolts on the circumference of the pulley. To remove the bolts, position an open-end wrench over each bolt and turn each bolt in a counterclockwise direction while grasping one of the fan's blades to prevent the fan from turning with the bolt.
   
2. Step 2 Pull the fan and clutch assembly away from the engine, then lift the assembly out of the engine's compartment.
   
3. Step 3 Remove the bolts which hold the fan to the clutch. The bolts are located on the back of the fan, and can be removed with a open-end wrench.
   
4. Step 4 Place the fan and clutch assembly on a flat surface with the clutch facing up, then pull the clutch straight up to disengage it from the fan.
   

4R100 or 4R70W?

Geartrain
Power is transmitted from the torque converter to the geartrain components through the input shaft and forward clutch cylinder.

• By holding or driving certain members of the gearset, four forward ratios and one reverse ratio are obtained and transmitted to the output shaft. The ratios are as follows:

GEAR RATIO 1ST 2.71 to 1 2ND 1.54 to 1 3RD 1.00 to 1 4TH 0.71 to 1 REVERSE 2.18 to 1
Input Shaft
The input shaft is supported by two bushings in the stator support. End positioning of the input shaft is controlled by the splines in the converter turbine and the overdrive planet assembly.
Output Shaft
The output shaft is supported by two bushings in the case and by the slip-yoke and bushing in the extension housing. End positioning is controlled by the parking pawl gear and snap ring or shoulder and by the reverse ring gear hub and snap ring.
Overdrive System
The overdrive planetary system consists of the overdrive planet assembly, overdrive sun gear, overdrive ring gear, coast clutch cylinder, overdrive one-way clutch assembly and the center shaft, as shown in the following illustration. The overdrive planet assembly is splined to the input shaft. The overdrive sun gear is centered by a bushing on the input shaft and held in place laterally by needle bearings on the reactor support and the overdrive planet assembly. The overdrive sun gear is splined to the coast clutch cylinder, which in turn is splined to the overdrive one-way clutch inner race.
The outer race of the one-way clutch is splined to the overdrive ring gear, which is splined to the center shaft. The center shaft is centered by the forward planetary assembly and is laterally held by needle bearings on the center support and the overdrive planet assembly. The center shaft is splined into the forward clutch cylinder.
Two friction clutches are assembled in the overdrive planet assembly. The coast clutch is splined between the coast clutch cylinder and the overdrive ring gear. The coast clutch is activated to perform engine braking in MANUAL 1, MANUAL 2 and third gear with the transmission control switch engaged.
The overdrive clutch is splined between the case and the coast clutch cylinder. The overdrive clutch holds the coast clutch cylinder and, in turn, the overdrive sun gear, to permit the planet assembly to overdrive the ring gear.
--------------------------------------------------------------------------------------------
Forward Drive System
The forward drive system consists of the forward clutch cylinder, intermediate brake drum, intermediate one-way clutch, input shell, forward ring gear, forward ring gear hub, forward/reverse sun gear and the forward planetary carrier and forward planetary gears.
The forward clutch cylinder is splined on the center shaft. The forward ring gear is piloted on the forward ring gear hub. Thrust bearings on the forward planet assembly and forward clutch cylinder hold the forward ring gear hub in place.
The intermediate brake drum is radially supported by bushings on the center support and is laterally controlled by thrust washers on the forward clutch cylinder and center support. The intermediate brake drum has the inner race of the intermediate one-way clutch press-fitted on its pilot. The intermediate one-way clutch's outer race is splined to the intermediate friction clutch, which is splined to the case. The intermediate brake drum has lugs that are slotted into the input shell to form a mechanical connection. The input shell is splined into the forward/reverse sun gear. The forward/reverse sun gear is common to two planetary gearsets. The forward planet is splined to the output shaft and is laterally positioned by needle bearings on the sun gear and on the forward clutch cylinder, as shown in the following illustration.
Two friction clutch assemblies, the direct clutch and the forward clutch, are shown with the forward planetary assembly. The direct clutch assembly splines the forward clutch cylinder to the intermediate brake drum. The forward clutch assembly splines the forward clutch cylinder to the forward ring gear. The forward clutch is activated during all forward gears. While in third or fourth gear, both the direct and forward clutches are applied to hold the forward planetary assembly and enable it to act as a solid shaft.
In second gear, the intermediate clutch assembly holds the forward/reverse sun gears. It is applied, along with the intermediate one-way clutch, to hold the intermediate brake drum, input shell and forward/reverse sun gear. In higher gears, the one-way clutch overruns.
----------------------------------
Low and Reverse Drive System
The reverse planetary assembly consists of the reverse planetary carrier, reverse planet gears, the reverse ring gear, the reverse ring gear hub, the reverse clutch hub and the low-reverse one-way clutch assembly.
The reverse ring gear hub is splined to the output shaft and to the reverse ring gear. The reverse ring gear hub is laterally held by a needle bearing on the inner race of the low-reverse one-way clutch and a snap ring on the output shaft. The reverse planet assembly is splined to the low-reverse clutch hub. The low-reverse clutch hub is connected by the reverse clutch to the case. The inner race of the one-way clutch is bolted to the case.
The reverse clutch assembly is activated in REVERSE gear and in MANUAL 1. The reverse clutch bypasses the reverse one-way clutch during coast and MANUAL 1. The reverse clutch holds the reverse planet assembly in REVERSE gear to enable the sun gear to drive the reverse ring gear in the opposite direction.

Apply Components
The following information describes the operation of the three 4R100 one-way clutches.
One-Way Clutch—Overdrive
The overdrive one-way clutch, shown in the following illustration, transmits engine torque from the overdrive sun gear to the overdrive ring gear in first, second and third gear range. The overdrive one-way clutch transmits power when the sprags are engaged between the inner and outer races. The inner race is splined to the coast clutch cylinder, which in turn is splined to the overdrive sun gear. The outer race is splined to the overdrive ring gear.
The overdrive one-way clutch engages whenever the overdrive planetary system attempts to drive the overdrive sun gear clockwise when the overdrive ring gear has a counterclockwise torque from the vehicle. When torqued counterclockwise, the overdrive one-way clutch engages and acts as a wedge to lock the sun gear and the ring gear together. During coast, the overdrive one-way clutch enables the ring gear to overrun or spin at a faster rate than the sun gear.
The overdrive one-way clutch overruns when in overdrive (fourth gear). In overdrive, the coast clutch cylinder is held by the overdrive one-way clutch, which in turn holds the overdrive sun gear. This causes the overdrive planet assembly to walk around the sun gear and overdrive the overdrive ring gear. The inner race of the overdrive one-way clutch is thus held stationary while the outer race is allowed to overrun clockwise.

Possibility, you may have intalled the clutch disk backwards.... if so, the disk hub is torqued against the crankshaft hub preventing engagement of the clutch. 2003 TIBUORN DUAL MASS FLYWHEEL AND CLUTCH DISC ASSEMBLY INSTALLATION PROCEDURE DESCRIPTION: The 2003 MY 2.7L Tiburon vehicle equipped with the 6-speed manual transaxle employs a dual mass flywheel system. The 2003 Tiburon Shop Manual does not show the clutch disc assembly with the dual mass flywheel. This bulletin provides information about how to assemble these components.
