    Glide issues I think

    I have a 68 GMC p/u, 565 bbc 1000 hp and Abruzzi pro glide 180 gears ect. Truck weighs 3300 wet and has 10 passes since build.
    Last time out it did something I cant figure out , I drove thru the water box stopped started my burnout in 1st shifted to 2nd as she began to move and the tires stopped spinning. It didnt feel like it was free spinning but I could tell something was up, I pulled to the line staged and left off the brake at 3000 rpm. All went normal as far as I could tell pulled hard all the way and shifted fine, I ran my best time so far.
    I know something isnt right and before I pull the pan I was hoping you guys could tell me what to look for.


    Thanks
    Keith

    Keith could be a few things other then trans also.

    Marco is always very good to customers, heck he is good to non customers also. I've had this happen to me before though, clutches were wasted in mine, fluid got so hot and thin the trans was slipping. If you see any metal/trash you'll need to really dig into it.

    Maybe I missed something in the post??? What was the problem?
    Tires stopped spinning after burnout but sounded like it was still spinning??? Maybe you accidently shifted it into neutral?

    I have a Abruzi racing powerglide in my car and I love it, no problems what so ever, and talk about great customer service they are the best!

    If it were me I'd just pull the pan and do a looky loo. You'll see some clutch dust and thrust bearing material but it should be minimal but if its looks like your panning for gold and you hit the jack pot, do some investigative surgery.

    Goodluck, Charles

    It feels like it is still under a load when tires stop spinning and it stops moving also, engine is still at about 5500- 6000 rpm and tires are not moving, seemed normal down the track shifted pulled hard , then again its only been down the track 10 times so maybe 2nd isnt pulling as hard as I think.
    Just to be clear I am in no way saying anything disrespectful towards Abruzzi trans or Marco , just added the fact I have one of his to show it is a probuilt piece.
    Matter of fact if anything is wrong with the trans I attribute all damage to my being way green and might be doing a no no off the line or in the burnout box.
    Anyway I pulled the pan today and the fluid was a little dark but not to much, smelled like new and there is a very small amount of metal in the bottom of pan. I pulled the trans and I plan on taking it to a local guy for a check up. Hopfully he will be able to enlighten me on the problem and what caused it.

    Also what blows my mind is after it did this the first time I went from 7.00's to 6.60's but my MPH was down ???

    Hell I may not have a problem, like I said before I am fairly new to racing but I am learning as fast as I can.

    Thanks

    hang on, this truck can not weight 3300lbs and run a 6.60 in the 1/4 with 1000 hp and it better not be running a 6.60 in the 1/8 mile with a 1000hp. Just wondering , And what is the mph? Did you adjust the band on the glide before?

    I agree if its 1000hp and running 6.60's something else is wrong.

    Whats the 60ft and 300ft times, maybe a sprag has went out in the converter ?

    Just a thought here, since your new to this.
    Sometimes when you do a heavy burnout and you really get it wound up in high gear and then you try to power out of the burn-out ( I.E>let off linelock) it will feel like it is on ice and will not hardly move, just let off the gas or feather it till the tires stop spinning then she'll bite and you go ahead and power out of the burnout.

    Very posible to be convertor. Had this same thing happen on my friends truck last weekend. Tires actually stopped when he launched, but the motor didn't over rev. When trans was opened it looked good, but a fin was broken in convertor which caused some other damage in it. Both were 4 years old and needed freshening anyway.
