    Default C6 Manual, 1st to 4th

    I own a 2005, 6 speed manual. The 1st to 4th feature is a bit of a pain.

    I heard about a bye pass that gets installed on the transmission and a special fuse that can be used to bye pass this "feature". Anyone try one of these? Any recommendations? I attached a link to one of the bye passes.

    Thanks!

    BTW, love the podcast, I listen every week. The "new" format is great, more focused on our passion.....

    Hi,

    You can

    1) Rev it a little higher before you shift, that will eliminate the forced 1-4 shift

    2) Bypass at the tranny, it will melt at a track day if you get the tranny hot enough

    3) Tune it out using tuning software

    4) Try that fuse in the fuse box, I actually have not seen that one.



    The 1-4 shift helps us beat the gas guzzler tax so I'm ok with it.

    Once the car is warm just shift out of first past 22 mph and you ll never activate the 1 to 4 shift.

    I never shift out of first in a car once its warmed up and I never activate the skip shift feature.

    Not a fan of the skip shift bypass.

    Thank you for your responses.
    I did not realize the bye pass at the tranny could melt! Count that out...
    Around town I sometimes shift at lower RPM. Coming out of my driveway I have a hill, I generally keep the RPMs low until its warm. However, if I don't, I get bogged down due to the hill. I hate having the car tell me what gear to select, it can't see the hill...

    I might try then fuse. If I do, I'll report my success.

    This forum is great, sharing real world experience and our passion.

    Thanks!

    Welcome and I'd really suggest just shifting out of first after 22 mph when the car is warm.....you'll never activate the skip shift ....I don't think the skip shift works when the engine is not at operating temperatures.

    I do it naturally because I just like to hear the engine rev a bit.

    I think 2500 or 3000 rpms in first with a fully engaged clutch might put you over 22 mph and you'll never be bothered..again...

    I am glad your enjoying the site

    I tend to be grateful gm figured out a way to avoid the gas guzzler tax and still give us insane levels of performance.

    The dam government forced gm to do this...

    The bypass won't melt with normal street driving as long as you tie it up properly. I've had one on mine for 8+ years with no issues. I highly recommend one so that you can drive the car as you want to, there are times in a middle of a turn that I don't want to rev the engine or shift to fourth (but that's just me). The CAGS was a win/win for the consumer as it kept the vehicle from having a gas guzzler tax, and it is easily by-passed and inexpensive to purchase. Good luck either way.

    Good to know. I dont track my car somit should not be an issue. I'm leaning towards trying the fuse, it's only $15 and easy to install. It it fails, I did not invest much and can try another solution. As long as it won't hurt my car, that's my primary concern.

    True, mine lasted ok on the street & only melted once I hit the track.

    Yes, I just rev past that thing and I never notice it. It does not take much to rev past it really, no grandma shifts.

    Melting on track conditions? I think bypassing the bypass amkes sense.

    Yep, the day I got the tranny temp warning on the dic (274 deg F) IIRC it melted. If the vendor had the sense to use a higher temp plastic it would have been fine I suppose.
