    Lb7 quick start?

    I know what he is describing as I have noticed the exact same thing with the lb7 vs lbz. The lb7 take a few revolutions to start and the lbz starts almost instantly. My lb7 has brand new batteries also. Sent from my SM-N950U using Tapatalk

    Fleece tap shifter install

    Positive, it says fleece on the box. I don't think the new ones come with the box it's just the 2 connectors. Sent from my SM-N950U using Tapatalk

    Fleece tap shifter install

    I bought a used fleece tap shifter and need some help on the install. I looked at the new instructions but mine has additional wires in the harness like a vss, tps wires and a blue/white wire not labeled so I assume mine's an older version. Does anybody know where these go or have a set of the...

    LB7: Looking to get an LB7

    With that many miles, if it's not smoking or has fuel in the oil there's a very good chance they have been changed. The only problem is if they were changed a long time ago maybe around 100k miles it may be time to do them again. If everything checks out good, you may could get by a while...

    2nd gear downshift

    2nd gear downshift

    I'm having some issues with my 3-2 downshift in my 03 lb7 duramax. I rebuilt the trans with Evans kit and a suncoast 1057 converter. I've put around 7k miles on it, all of my up- shifts are perfect (except the full throttle 3-4 has a slight double shift) but I'm having some issues with the...

    Lb7 TCM tune process

    I know the autocal I have can't full flash in v7.5, so I guess that's why it won't work. Sent from my SM-N920R4 using Tapatalk

    Weird downshifting

    Mine will downshift to 4th sometimes if I'm hard in the brakes when not in tow haul mode. Sent from my SM-N920R4 using Tapatalk

    Lb7 TCM tune process

    Really? Seems like I've been reading that it's no problem to do with the autocal. I have a tech 2, is it possible with it? Sent from my SM-N920R4 using Tapatalk

    Lb7 TCM tune process

    I'm just now getting around to doing this tcm flash, I have an 02 tcm tune from Kory that I'm trying to flash, but it says AL5 full flash not supported. Does anyone know the correct steps to full flash it? I've already read and saved my stock tcm tune and uploaded the new tune in the autocal...

    LB7 TCM replacement

    Ok, I didn't think a full reset of the taps was necessary after a tcm replacement. I have a Chinese Tech 2 coming in a few days so I'll try it out. Sent from my SM-N920R4 using Tapatalk

    LB7 TCM replacement

    Is a tech 2 relearn the only way to do it with this situation or would a relearn from the edge cts work? Sent from my SM-N920R4 using Tapatalk

    LB7 TCM replacement

    I have a 2003 duramax and wanted to try some different tcm tunes after building my trans with the Limitless diesel kit and a suncoast 1057 coverter because I couldn't get the 3-4 shift to clear up from double shifting. Everything else shifts pretty good, I occasionally have a semi harsh 3-2...

    LB7: Injectors, bent rods, or?

    Is the rod bending usually a once and the damage is done sort of thing or is it a slow process that will eventually show up with these symptoms? Sent from my SM-N920R4 using Tapatalk
