    Im tryin to find out where to get a set of shift rail seals for my 205. I called my local GM dealer and they coulden't get them, which I think is bull $h!t. If I can get them are they difficult to install?

    Thanks:D

    Going to call up the dealer and tell them how lazy and stupid they are? :)

    GM PART # 3979626
    CATEGORY: All
    PACK QTY: 1
    CORE CHARGE: $0.00
    GM LIST: $11.39
    OUR PRICE: $6.75

    You might be able to get them cheaper somewhere else though. National drivetrain comes to mind, as well as vendors here that deal with NP205 stuff.

    It looks like the t-case needs to be disassembled to change the shift rail seals. Is this right? Has anyone done it?

    Yes, complete tear down of t-case to replace those seals. I would also check your shift rails for wear. They have a tendency to grove from the seals and continue to leak unless replaced.

    No you do not need to do a tear down to replace the shift rail seals. I did mine in the driveway without even droping the drive shaft. The part number for NAPA is 7443. Just get creative i used a small screwdriver, seal pick and a hammer.

    Your right now I think of it. But I would still check those shift rails closely.

    One "trick" I've tried a few times is to seat the seal just a hair further out than it was stock, so the seal surface is moved. :)

    I know they make speedi-sleeves for a lot of things, but this is cheaper lol.
