    Transmission Lines

    So I've been in the works of replacing the lines and also soon installing a PCV oil catch as well as a external trans cooler. The trans cooler is taking a backseat for now, I'm going to do the lines first off. However, when the line was being removed from the rad, seems like something happened, because now I can't thread it back in. Anyone got any suggestions besides a larger thread, teflon/loctite combo? Thats my first thought, but figured maybe someone knew a little better on this.

    Re: Transmission Lines

    This probably won't help, but I had the dealership flush/fill my tranny.. When they removed the lines from the radiator, they stripped the threads and had to REPLACE the radiator.

    I was shocked, but apparently you're not supposed to remove the lines or something.

    Pft, what a joke.

    I had gone for a trans flush / fill about 2 months ago. But thats definitely a good idea for people who may need a trans flush anyway. Kinda like knockin two birds with one stone.

    Re: Transmission Lines

    ya the stripped lines is the main reason for the line blowing off.
    sorry to say but it looks like you need a new rad at a price tage of 350 i think or a aftermarket external cooler to the tune of 40-150

    anyone see these ones? they look kinda cool, but will they work??

    this design is more common but those fittings are going to need some adapters.
    http://cgi.ebay.com/ebaymotors/UNIVE...Q5fAccessories

    i like the look of this one with all the parts.

    someone else has one with a ballbering that stopper the flow till the tranny was at pooerating temp.. i think it was txbest... ide like to know the model of it.

    or more specifically

    What do you think? Think retapping isn't worth it? If I have to get a new rad, then I'm definitely not going for the external cooler. I think I might go the route of doing the ext cooler and tapping into this rad though.

    Re: Transmission Lines

    That post was about a plastic tube on the top of the rad, he broke the plastic.
    Re-tapping...I dunno man, its weak metal to begin with...your call.
    The point of running a external cooler is to bypass the rad and its faulty fittings, its not to add more cooling to the tranny.

    Re: Transmission Lines

    New lines + external cooler = done.
    Now I'm off to home depot for the other parts for the PCV oil catch can. Thanks for the heads up on the whole setup. I'll hopefully have some pics of the PCV setup very soon.

    Re: Transmission Lines

    od...sorry to say it, but you either need to do the external cooler now or replace the rad. as far as a new rad for $350+ seems a little crazy to me, i bought an aftermarket one off of ebay two years ago for $154 shipped to my door, so shop around. as you know i added the external cooler on my CTS when i had it, and out of the ones mike listed a few post up, i used one very similar to the third one he posted and got it from autozone

    This is the external cooler for the trans. I have it mounted behind the grill. Underneath the car would have been a bad idea here in NYC. It would have been damaged, cracked, lost, etc

    Re: Transmission Lines

    QUESTION: When you (whomever has done it) installed the ext. cooler did you just cut the trans line and add the extra length? or did you replace the whole thing with a different kind of connection set up? (not sure if I understand my own second question)

    I guess what I ment to say was did you just use a hose with clamps at both ends? oh heck ...... can someone just tell me how they did it and if possiable show a couple pics of how you connected the trans lines both at the cooler and at the point where it attaches to the whatever its called (long day and frustrated that I didnt get it finished in one day !!!)
