      Transmission Removal

      Drain the transmission by removing the ATF sump drain plug




      Remove the ATF filler tube and ATF cooler lines




      Remove the transmission bump stop and the reinforcement plate at the bottom of the bellhousing by removing couple of Torx/Hex bolts




      Working through the opening in the bellhousing, remove the (3)bolts that hold the torque converter to the drive plate




      Support the transmission from below and remove the rear transmission by removing the bolts that hold them to the body. This will lower the rear of the transmission a bit.




      Using long extensions, removed the torx bolts that holds the transmission bellhousing to the engine. Also you need to removed the bolts that hold the starter to the transmission bellhousing.




      Remove the inspection grill from the bottom of the bellhousing for access to the torque converter. Use screwdriver or lever to apply pressure making sure that the torque converter stays firmly mounted to the transmission.




      After removing the transmission off the engine





      Yay!!!! finally got it off...

            Could you do me a big favor and compare lean angles on the two crossmembers? I have the feeling that my tranny got swapped (because my car was originally automatic) and that they used the auto tranny with some modification. That's something I've wanted to fix for a while...

            Yes, i'll be using Getrag 260

              Regarding the problem im having with the pedal assembly. After 6 beers (Corona) I started thinking to how can i solve the problem. Then it hits me. Why not just swap the bracket thats holding the pedals. As you can see on the pics. The pedal assembly from 92 M-technic w/ airbag mounting bracket is much longer than the auto's pedal assembly. THIS WILL NOT WORK!!!!....The pedal bracket from the auto doesnt have the lip (spring guide) which the compression spring (clutch pedal over-center helper spring) sits....



              all that needs to change is to remove the pedal shaft bolt & transfer just the manual pedals over to the automatic bracket



              Here's a pic after swaping the manual pedals to the automatic bracket.

                  just came back from my 2weeks vacation....
                  heres some more parts for the conversion.














                  Removing the flywheel. When removing the mounting bolts, hold the ring gear stationary using a holding fixture. I actually used an electric impact wrench to remove the bolts.











                  After removing the flywheel




                  Heres a pic of the transmission




                  Also installed a new clutch slave cylinder.

                    Sorry for the slow progress. Just came back from my long vacation.

                    Well, here it is again,
                    Installing the flywheel and Clutch.

                    I purchased new flywheel bolts and coated the threads with Loctite



                    Now its time to reinstall the flywheel. After the long vacation, the flywheel started to rust, so i slightly sanded it down to remove the rust.




                    You must use a torque wrench and a flywheel lock to tighten the flywheel. Also tighten the bolts in sequence alternating between opposite sides fo the flywheel




                    Shows the flywheel installed with all the bolts properly tightened to the proper torque.




                    Clutch alignment tool


                    I started installing the clutch disc and the pressure plate onto the flywheel and realize that i forgot to get new pressure plate bolts. so i guess....

                    TO BE CONTINUE......

                      With the flywheel mounted, take your clutch alignment tool and place it in the center of the pilot bearing. Install the clutch disc



                      Then install the pressure plate onto the flywheel, compressing the clutch disc





                      Use new pressure plate mounting bolts




                      Tighten the pressure plate mounting bolts evenly until the clutch disc is firmly held in place.






                      Tightened pressure plate bolts down to its proper torque, then remove the alignment tool.

                      Now on the pedal assembly

                            both lines can be unbolted from the radiator with no ill effects. They have to be snaked out from underneath the car unless you remove things in the engine compartment

                              Removing the the (2) transmission lines

                              Shows how the lines are attached to the front transmission cooler, which is located in front of the engine radiator (shows the upper line)



                              (shows the lower line)





                              Loosen using the correct wrench. You should be able to pull the lines out of the connector.





                              The line can then be snaked out and around the suspension for removal. Pic of the transmission line after removing.




                              Shift coupler




                              Mount the coupler on the transmission and tap in the pin that secures it to the selector shaft. Make sure that you place the small retaining clip on the selector shaft prior to tapping in the pin.






                              When the pin is tapped in, move the retaining clip to cover.




                              Now the Transmission...



                              Lightly lubricate the clutch disc splines and the transmission input shaft splines




                              Also grease up this rubber piece





                              Install the throw-out fork. The fork is attached at one end with a small metal clip.




                              Use grease to pact the release bearing lubricating groove and to coat the guides.




                              Install the release bearing




                              Pics after everything assembled
