    Ls7 clutch + tranny rebuild

    I have my ls7 clutch in and my tranny rebuild kit will be getting picked up tommorrow morning. This job will be starting most likely the start of next month.

    Any tips and tricks or things to avoid before I begin !?!?

    I have the directions from GMs "SI" (service information). Just looking for any bumps in the road that you guys have encountered.

    Thanks for any info and help !!!!

    Can't help but good luck anyway.

    Is a transmission rebuild straightforward enough that someone could follow a detailed instructional and accomplish with unlimited time? I assume it's a skill that requires lots of experience.. which is the reason people get $1000s to rebuild.

    I've always wanted to attempt it based on videos I've seen. Other than there being 1000 parts and therefore 1000 ways to foul it up, what could go wrong? You always have the option to surrender, ship it off to RPM in pieces, and pray they don't charge you double to sort out the mess.

    the tranny rebuild is vary straight forward. pm me if you need any help. best tip i can give you is to lay things out as you take them out in oreder then dont touch the parts untill your going to replace/ reinstall them.

    Okay perfect I'll definitly use a large table and set that all up. I'll MSG you if I run into any road bumps. Thanks for the help.


    Would you say the ls7 clutch is a noticeable difference over the oem?

    Most definitely different, cadillac should have put the ls7 clutch and flywheel in from tthe factory. It makes this car that much more fun to drive..😜

    Perfect im glad I made the choice to go with it then. I bought the slave cylinder spacer to do te conversion but I hear using a ls7 slave cylinder could be better ?!? Are they pretty pricey or will the spacer work fine ?

    use the slave cylinder. Then you don't need the spacer. Then also you dont have to worry about your slave going out since your already in there and have replaced it

    pilot bearing...... If your in there you might as we'll do it just in case its gonna go out soon in your car. Don't wana pay all that labor again to have them take it apart. I think it's only around 20$

    Well she's going in this weekend . Ls7 clutch. Ram aluminum flywheel. Ls7 Slave Cylinder. Tremec Master rebuild kit. Creative steel shifter bushings, and that should probably do it.

    Sub'd for updates. Thanks for linky as well Dan.

    Also, anybody have a picture of this 'notch' that has to be made to the bell housing? I'd like a better idea of what needs to be done.
