Lift edges of shift boot. |
Disconnect wiring for illuminated shift knob, if installed. |
Pull shift knob straight up to remove. A sharp tug is required. |
Remove foam insulation pad if fitted. Locate connector for reverse light switch wiring, disconnect it. |
The purpose of removing these items is to allow the shifter mechanism to be removed from beneath the car if clearance is an issue. |
Support exhaust system |
Remove nuts from header flange. |
Loosen 13mm bolts on brackets and remove rubber hangers from rear cross member |
Remove muffler bracket and lower exhaust from car.
Remove heat shields from above exhaust. Shield styles and amount of bolts vary between vehicles. |  |
Remove the three 19mm nuts and bolts securing the "Guibo" coupling to the transmission. Leave the Guibo attached to the driveshaft. |

Loosen threaded ring at center support. This is best achieved with two large pairs of pliers, apply one set of pliers to the threaded ring (green arrow) and the second set to the weld in the driveshaft tube (yellow arrow). The weld is a rough surface and gives good grip, preventing the pliers from slipping and scarring the tube. It is also the strongest section of the tube.

Loosen ring approximately 5 turns.

Remove bolts from center support, push driveshaft rearwards to collapse slip joint at threaded ring, pull center of driveshaft down and forward end will come off transmission.
CAUTION: Drive shaft is balanced as a unit. Do not allow halves to separate without first ensuring alignment marks are present.
Remove bolt from header bracket on right side of transmission |
Remove the four 19mm nuts from bell housing studs. Upper left bolt may require crow's foot or odd shaped wrench. Remove exhaust bracket. |  |

Support transmission and remove the four 13mm nuts from transmission cross member.
If bolts begin to spin, lower transmission slightly to put pressure on bolt. Bolt is held in place by a rectangle machined section in the bolt resting in slot in the floor. The slot allows variable positioning of the cross member.

To remove the bolt from the floor, slide it to the end of the slot, push up, turn 90° and drop out enlarged hole at end of slot.

Remove the two 13mm nuts on the bottom of the transmission mounts and remove cross member from transmission. The cross member does not have to be removed but gives easier access to the transmission. |
Unbolt forward end of shifter from transmission by removing the two 13mm nuts. Remove circlip from selector rod and remove rod end from joint. |
Slide transmission out of bell housing. Do not allow transmission weight to rest on input shaft. |

### If bell housing is to be removed :

Remove throw out bearing from clutch fork if it did not come out on transmission input shaft. |
Remove two 13mm nuts and set aside clutch slave cylinder. |

Remove the two 10mm bolts securing protective cover to the crank sensors. Remove the two sensors from the left side of the bell housing. Take note of relevant location of sensors, mark sensors and locating holes in order to return each sensor to it's correct hole.

Remove third sensor from the upper left of the bell housing.

Remove bell housing bolts and lift off bell housing. |

### Installation

Place transmission in gear and rotate output shaft flange while sliding input shaft into clutch assembly. This will aid in aligning the input shaft splines with those in the clutch disc.
Ensure that slave cylinder piston is straight and contacting clutch fork at the correct angle.
Replace gasket and nuts at manifold flange. Use copper nuts.
Install manifold nuts and muffler brackets and tighten to correct torque before installing other mounts.
Correctly positioned exhaust must have tailpipes in center of opening in rear valance. |
Install transmission bracket on exhaust so that there is no stress on either part.
Install rubber hangers and brackets at rear sub-frame and position bracket so that rubber hanger has slight tension only. |
If Guibo has been removed from driveshaft, ensure that arrows on Guibo point to a flange. White arrows show position of arrows on Guibo. Green arrows show orientation of those arrows. Each arrow is pointing towards either the transmission output flange, or the driveshaft flange. |
Pre-load center support by moving forward 4 - 6mm from it's relaxed position, before tightening. Ensure Guibo is straight. |
