This approval gives you full access to the site, to pictures, and to post, among other things. To be able to enjoy the full potential of the board for you, you need to be fully registered.. and that's easy.. Just send an email to me at jim@trishieldperformance.com and I will verify your registration. This policy will remain in effect indefinitely, as it has completely eliminated the bad actors from our site, who would spam and hack it, once they gained access. Thanks JW

Turbo 400 converter?? Help

    roubd 2 on my tranny. Were trying to trace where my leaks are coming from. So far my tranny guy is pretty confident no cracks in the case. A little out of the the dip stick area. Needs a new O ring and maybe some silicone and only out of the sensor. But what looks to be the problem is the torque converter. The neck looks to have wear. Right now I’m running a 2400. It’s a Buick 430 with a little bit of performance upgrades. Not a ton over stock. The cam I have is a Ta 118.
    Can any one help me on what a good brand to go with. My last was a b&m. This tranny is built to stage 3 specs.
    My cam specs are
    VALVE LIFT

    • STOCK 1.55 RATIO:
      IN: .478”
      EXH: .475”
    • TA ROLLERS 1.60 RATIO:
      IN: .494”
      EXH: .491”
    DURATION
    • AT .050
      IN: 228
      EXH: 247
    • ADVERTISED
      IN: 276
      EXH: 295

    Larry I’m still working on my overheating issue. I reached out to TRP since I live in Wisconsin and he gave me a name to a guy that is local here. They both believe exactly where you were leading me to late ignition/to much timing or lean air fuel mixture. So soon as my tranny is back in my car I will be bringing that thread back up. Thanks.

    Took another look at that thread. Last we left off, it looks like you have way too much timing. The distributor you are using is the problem. It needs to be modified for less mechanical advance, or you need to buy a different distributor. Everyday Performance (techg8) may be able to help on that front.

    I would try to adjust the initial timing down to 0* to see if the engine will run at that timing. If it won't you may have a vacuum leak. Get a vacuum reading as well and post that.
