    Thanks, Steve. It added another complete harness to the car running this transmission. I routed and rerouted and even rerouted again after this picture. I feel your pain my friend, the struggle is real.

    I purchased a trans cooler for the car from Jegs. This is a universal cooler with 1/2" pipe female ends that I adapted to -6an male.
    Not sure if I am going to bypass the primary cooler in the radiator or link them.
    this sounds like a question for Larry, AKA the wizard. I do have all the right fitting
    to run both.
    I just hope it fits between the condenser of the grill.
    I've said it before, there's not much room for upgrades in a 67GS

    Ya.Thats me. My project is back-burnered. I am actually teaching middle & high school kids this stuff and have not gotten back to my project. It would be more motivating if it were a necessity.

    The cooler I ended up using is a 9 x 9 x 3/4" I said it before there is no room at all in a 67 with air.
    I hope the bumper brackets don't pull the cross bars back to far too. ugh.
    FullSizeRender (3).jpg , FullSizeRender (2).jpg still have to mount the other side.

    External trans cooler is complete. this completes the install of the 4L80e transmission. I have been driving in and out of the garage but haven't been on the open road. that post will come along with computer adjustments and trans accesories, like switching to manual paddle shift hooking up the factory tach. and the digital to manual speedo control.

    Hey, just wondering what the latest on this project is? Did you make it onto the road yet, Joe?

    Hi Ken,
    I haven't made it to the road but I am driving in and out of my garage. I also had my first burn out in my driveway. Good times. I have been trying to get paint done. that has been a slow process due to my painter being so busy. here' s where I am today. not far from exhaust and upholstery.

    What is the part number for the adapter plate? The link for the old thread no longer works. Does it come with a shim the space the converter properly too, or did you have the converter made to compensate for it?

    Probably this one, https://www.summitracing.com/parts/trd-0061/overview/

    I would imagine you just need to use washers to properly space the converter. You need to check that anyway with a new converter installation.

    He said it was a TCI one, but that's probably What it looks like. I know the washers work but if you're having a converter done for the set up, might as well get one with the correct length snout

    This thread will be a huge help when I put a 4l80 in my 67 GS. Thanks for sharing your experience with us! I love the idea of trying to make all this look factory. With a 67 aircleaner on it seems the only way someone will know is if they see the shift indicator. The indicator truly is the best part to me. A nice subtle touch.

    Are you using the factory 8.2? I might be able to copy off your driveshaft measurement.

    Thanks!

    Does this have an sfi cert on it?

    The air cleaner is a power killer and really just a show piece. A K&N drop air cleaner is what I'll use on the street. The rear is a 1971, 8.5 . It has moser 30 spline axles and a eaton posi. HD retainers and studs. For this I worked with Jim @ JD Race, this rear is one inch wider than the stock 67 and puts the tires right inside the rear lip. I'll add some additional back spacing to the new wheels when the time comes. I kind of got it figured at 15 x 8, 5.5bs

    The flex plate and converter are a sfi approved

    I agree on the aircleaner but it is a great touch for car shows. For street driving or a trip to the track its worth the extra power to swap to an open element. Saves some wear and tear on the 67 aircleaner too.

    8.5 is definitely a nice rear. I wish I kept my 72 rear. I have a 12 bolt I could put in but for the power level I want and for the sake of originality I have been leaning towards building the stock unit since parts are a little easier to come by compared to the later 8.2s.

    I thought about looking for 17 inch wheels but you almost never see a 67 with factory wheels anymore. Id like to get a set of the disc brake wheels but in 15" From what I understand Buick just used chevy slots with trim ring and painted to match body. Backspacing is definitely more of a concern on these cars compared to 70-72.

    I have 15 x 7's on now. I went disc front and drum rear. from what I have read, there is a ton of room in the 67 rear. I would like to try a 15 x 10 just to see. the extra 1/2" on each side may allow for it. better to put on a 15 x 10 rim then risk a miss measure at 300 a pop for a wheel. with custom BS. non returnable.
