Removing and Installing a T56 Transmission...
Tools Required:
  • 8mm, 10mm, 12mm(12point), 13mm and 15mm Sockets
  • 3/8" and 1/2" Drives
  • Various Extensions
  • Needle Nose Pliers
  • Pry Bar
  • Torque Wrench
  • Transmission Jack
  • Floor Jack
  • Four 6 TON Jack Stands
Torque Specifiction:
  • Battery Terminal = 62 lb - in
  • Shifter Boot = 89lb - in
  • Shifter = 29 lb - ft
  • Driveshaft = 83 lb - ft
  • Crossmember to Frame = 30 lb - ft
  • Transmission to Bellhousing = 26 lb - ft
  • Bellhousing to Motor = 26 lb - ft
Materials Needed:
  • Exhaust Manifold Gasket
1st - Loosen the tension on the clutch cable.
Firewall Adjuster: Turn the adjuster in towards the firewall.
Stock Adjuster: Go underneath the dash to release the tension.

2nd - Use an 8mm socket to disconnect the negative battery cable.

3rd - Use an 8mm socket to remove the shifter boot bolts.

4th - Remove the shifter from the transmission. For an OEM shifter, use a 10mm socket.

5th - Raise the vehicle as high as possible in order to ease the work underneath the car.

Mid Pipe:
6th - Start by disconnecting all 4 oxygen sensors. FYI: The front passenger side O2 sensor is normally the worst sensor to disconnect. Be patient and DO NOT pull on the wires when trying to disconnect the connector!

7th - Loosen all 4 cat back exhaust bolts, but DO NOT remove them just yet! Due to various aftermarket exhaust companies, the socket size may vary. The OEM bolts are 15mm.

8th - Use a 15mm socket to remove all 4 mid pipe bolts. For the passenger side bolts use a 3/8" drive, socket, swivel and extensions to ease the removal. Once the mid pipe bolts are removed, remove the exhaust bolts and then the mid pipe.

Exhaust Manifold Gasket:
Note: During the installation, replace the passenger side exhaust manifold gasket. You might be able to re-use the original gasket. But, for a few bucks, a new gasket could help avoid an exhaust leak.

Driveshaft Bolts:
9th - Clearly index the driveshaft rear flange and pinion flange with a marker. FYI: Failure to index the D/S can result in a driveline vibration!

10th - Use a 12mm 12point socket for the driveshaft bolts. ONLY loosen 2 bolts half way and completely remove the other 2 bolts. The 2 bolts will hold the D/S in place for the next step and until you are ready to remove the D/S.

11th - Use a pry bar and detach the D/S from the pinion flange.

Note: If you can, index the output shaft of the transmission and the D/S slip yoke. This will help to insure that you do not introduce a drive line vibration that you never had before.

Inspection Cover Bolt:
12th - Use a 10mm socket to remove the inspection cover bolt. Once the bolt is removed, remove the cover by pulling and sliding the cover towards the back of the car.

Clutch Cable Part A:
13th - Detach the clutch cable from the clutch release lever. Push the clutch release lever forward(towards the front of the car) to create some slack for the cable. This should allow you to push the cable end piece up and through the exit point.
Clutch Cable Part B:
14th - Use a straight needle nose pliers to remove the clutch cable c-clip from the bellhousing.

15th - Now slide the clutch cable out of the bellhousing and place the cable out of the way.

Wiring Harness:
16th - Detach the rear 02 sensors from the crossmember.

17th - Disconnect the OSS sensor. Connector is on the driver side.

18th - Disconnect the reverse light activation switch. Connector is on the passenger side.

19th - Disconnect the reverse switch solenoid. The solenoid is located right next to the driver side shifter base. You can either wait till "Step 23" or go inside the car and disconnect it from there.

20th - Run all the driver side wiring harness towards the front of the car and out of the way.
Crossmember:
21st - Place the transmission jack underneath the transmission.

22nd - Use a 13mm socket and remove the crossmember bolts.

23rd - Lower the jack and the tail end of the transmission should drop a good 2 1/2 inch.

Transmission Top Bolts:
24th - Use a 15mm socket, 2 foot extension and a swivel to remove the top two transmission bolts.

25th - Now raise the transmission jack for the transmission to sit on it, but do not raise the transmission back up. There are a total of 8 bolts holding the transmission to the bellhousing. Various length of extensions come in handy here.

IMPORTANT: Loosen the top 2 bolts before loosening any other bolt on the transmission! Note: Best way to reach these top bolts is from the tail end of the transmission and using a long extension.

Removal and Install:
26th - Carefully detach the transmission from the bellhousing.

Note: Be sure that the wiring harness is not attached to the driver side/top of the transmission. The harness being attached to the transmission will eat up about an inch of room that you may need for the input shaft to clear the pressure plate fingers. During the install, attach the 1 o-clock bolt through the transmission breather bracket.
