    Can anyone help suggest the proper way to connect the shift linkage on my 1978 308 GTS? I have some photos that may help show my situation. I believe the transmission is currently in neutral. I talked with a Ferrari service manager who told me that I needed to be careful or I could bend the fork inside the transmission. Do I need to take the pan off the bottom of the transmission to get a view of the inside before proceeding? I can move the control rod shaft and reposition it in various positions but it doesn't seem to change gears. I have the adjusting sleeve, locking nuts, and fork to connect the control rod to the shifter rod. The service manual indicates the best place to start adjusting the linkage is to put the car into 2nd gear. I am unsure how to get the transmission into 2nd gear at this time. I would appreciate any suggestions. Thanks so much!

    Well, the first picture looks okay, but the next one looks wrong. The rod in the gearbox has a tang, or finger that engages the fingers of the three shift forks. The sleeve the bolt goes through, in your first pic its horizontal, and its probably engaged correctly. In the other pic the rod is way to far out and rotated far beyond engaging anything within the gearbox. You probably need to drop the pan, but I would first try to get that rod back into the position it was in in the first picture. You can probably "feel" the parts inside if your careful, and may be able to re-engage the tang back into the forks. The rod may need to be further out, or further in, than in the first picture, and it may need to be at a slight angle to the horizontal if the lower fork was pushed or pulled into a gear. Though you said the gearbox was in neutral?

    Here is a picture to help describe what is going on inside the gearbox. #1 is the gear shift rod, the part sticking out of the gearbox. #2 are the three shift levers in the gearbox. You can see that as the shift rod rotates, it aligns with one of the three fingers? You have to get that hooked back in there. My guess is you rotated the rod to far and slid it fore or aft and it de-coupled. I dont think you'll bend any forks very easily, they are pretty tough, but I wouldnt start it up or try forcing the lever around hard until you get it under control.

    Daniel,
    be careful not to loose the 3 balls and springs that come out of the 3 holes (on the last picture leftside...)

    what action caused this situation? if you find you have to drop the pan be sure to replace the shifter shaft seals. they are inexpensive. basically just rubber o rings. do a search for shifter shaft. there is a very good thread that details the adjustment of the shifter. please post results. preserverance furthers.

    Artvonne, theunissenguido, and tatcat,

    Thanks so much for your suggestions. I bought the car in April and have been completing the restoration the previous owner started and almost completed. Eric spent the last four years rebuilding the suspension, rebuilding the transmission, installing a custom exhaust, redoing the brakes, reapostered the interior, installed a new Alpine AM/FM Multi CD Radio; well you get the idea. The receipts added up to more than $15K. He decided finishing the remodel on his house was more important. Eric kept the plates that were on the car - REALPI - (He is a helicoptor pilot instructor and also flys for the movie industry in Hollywood).

    This is the last step to getting the car on the road. I heard it run before buying it, but since he had not connected the shift linkage it was not possible to drive the car. (Eric had removed the header pipes in order to powder coat them.) I have pushed it around the shop floor, so I know the transmission is in netural.

    I will put the rest of the shift linkage together, take some photos, and report back by Saturday. Thanks again.

    Dan

    Almost forgot to ask about the rubber boot that goes over the gear shift rod. The last of the three pictures I posted is a picture of the rubber boot. There wasn't a retaining device to hold the boot in place. There is also a metal lip piece that acts to hold the boot in place. Will any thin retaining device work to hold this boot in place, or should I order the clip? Thanks again.

    On the picture the metal ring is still on his place. Take it of and put it inside the rubber boot. Then try put it back in place....you need to be patient...
    Good luck, Guido

    I had success with getting the rubber boot attached via the ring holder but not any luck getting the transmission shifting to work.

    I have drained the transmission fluid and will remove the transmission pan to get a better view of the gears and linkage.

    Does anyone know the best source for the gaskets? Thanks.

    This is what I imagined looking at the shop manual. The sump gasket is on the way and the sump drained. Have to run to Dallas this week, so won't get to pull the pan until this next Saturday. Will post photos of my progress. Thanks again.

    Having failed to get the transmission linkage connected I am attempting to remove the sump. I have removed all the nuts holding the sump in place but it will not come off. I appears something is keeping it from coming off. Any suggestions? Thanks so much.

    To remove the engine sump cover you have to remove the lower dipstick tube (which requires removing the upper dipstick tube) and maybe the oil temp sender. Do a search on "dipstick tube" -- many threads with good photos.

    That said, removing the engine oil pan won't do you much good -- you should remove the gearbox oil pan if you want to visually check the shifter action.

    Guess it would help if I took off the right pan. I thought this was the gear pan. Thanks for the heads up. Now that I have it loosened the gasket will need to be changed.. Thanks so much.

    Having removed the trans sump pan I was able to set the linkage correctly. Here is a photo of the correct alignment. Thanks for the help F-Chatters!
