    What do you think of this - shifting ?

    Video with engine off:
    Notice how I couldn't get into 4th, then when I went to 1st then 4th it went right in. Kind of random.
    Fresh GM fluid in the trans. Clutch has also been bled (3 quarts through it).



    Engine idling:
    You can see it resist on 3rd and 4th. It pops right in as soon as I let off the clutch just the slightest bit.


    Any thoughts ?

    It was suggested to try Amsoil in the trans; I might try it, but all these fluid changes start to add up, and the stuff in it is new. Figured I would check with you guys first.

    Although a transmission should pass both a static (engine off) and dynamic (engine on) shift test, shifting up and down through the gears with the car parked is not always very revealing. How does it behave (shift) when driving around a neighborhood or area where you are constantly shifting up and down through 1st, 2nd, 3rd, and 4th gear?

    Shifts fine through neighborhoods etc. I think it has kind of done as shown in the video as I've came to a stop before. I'm trying to remember from last year.

    All of my Manual transmission cars do this at one time or another (2-CTS-V's and 4-Corvettes). Shifts great when I'm moving. When I have this problem and I'm parked on a slope I let the car move a little. When I'm parked on a flat surface I will barely let out the clutch to move the gears in the tranny.

    If it shifts fine when you're moving I wouldn't worry about it. If it ever happens that you can not ret the car into 1st or reverse, no matter what you do, then is the time to start worrying.

    Nice to hear. I'll keep things on high alert for a while.

    Different time, different cars, different transmission - but I drove a Chevelle and a Sting Ray with 4-speed Muncie transmissions - and they, particularly when cold and standing still, could be an unholy bitch to get into a gear. The gears and synchronizer teeth had to be exactly aligned or all you got was a stick that went nowhere.

    Other thought was this trans has 3k miles on it; "possibly" needs wore in more *thinking positive*

    What lube does your transmission run, and how cold is it there in IN ?

    If these manuals are now running something like DEXRON-VI it should not be THAT hard to shift when moving.

    .......... 3kmiles - the thing should be as smooth as a baby's butt.

    It has fresh GM fluid in it. Its 30s and 40s now, but I'm pretty sure it was doing this last year before I put it away too.

    Its supposed to be a dex 3 fluid in a GM bottle.

    Re: What do you think of this - shifting ?

    DEX-VI is the new (2006) synthetic fluid - GM says it's 100% backwards-compatible with -III (which is now obsolete).

    Royal PITA - but in fair weather you could go to the new -VI fluid. It's said to be "slicker" than -III but I have no proof of that.

    I do run -VI in my STS 4-speed auto and it's tight and quiet.

    Re: What do you think of this - shifting ?

    There is a orage label above the fill plug that says Dext-III.
    I've read that supposedly that some synthetics are "too slippery" for my syncros.
    Had quite the debate when getting this trans put in via warranty. I had amsoil torque-drive in the previous trans and at first they wanted to tell me that could have caused it to fail; but in the end he did say he found out that being it was Dex-III rated I was fine.

    Same recommendation for my 2002 - for -III. BUT, GM now uses -VI for ALL the old -III applications.

    Check with a dealership service writer on a quiet Tuesday afternoon.
