    85 4+3 3rd gear off throttle stick vibration

    I have an 85 with the 4+3. I'm getting an off throttle vibration in 3rd gear. The stick will violently start shaking like it's coming out of gear. As soon as I touch the gas it goes away. Shifting is smooth and no grinding. I had the transmission out, and when I put it back in, I used a...

    Is there an online C4 parts catalog?

    Hi, I have my transmission out, and the rubber cover on the 3 shift rods going through the tunnel is rotted. I don't know what this part is called, but it looks like a piece of rubber with 3 rubber fingers for the rods. Is there an online parts diagram I can use to find this or any other...

    Please identify this mystery part for me

    Hi everyone, I recently acquired a 1985 4+3 that, you guessed it, needs work. I was disassembling the drivetrain, when I noticed that there was a washer floating on the transmission bottom, visible through the manual transmission drain hole. I removed it through the side cover. It's...
