I don't know of any way to drain a torque converter without removing it. It is possible to REPLACE the fluid by using a flush machine - but not to drain it...assuming you don't want to create drastic and irreparable damage to the transmission bell house and the torque converter itself.

    my fluid is black and separating it needs to be flushed

  • Johnny Tumlinson May 27, 2011

    Bear in mind - if you fluid is BLACK and burnt - you could have metal shavings and particles in the transmission fluid which is still allowing it to even work. If you flush the fluid - your transmission my not be able to function at all after.

    old school method was to drill a hole in the side so as not to damage converter clutch. even if you pulled trans you will not be able to totally drain converter. trans fluid is very high detergent if you flush it all the trash/****/varnish goes into the pan and WILL plug up the filter.
    if you must have red/pink fluid then best to drop pan and change filter and gasket, let sit overnight it will drain out quite a bit, reinstall and add 4qts , start car add about4 more then start checking level

    The Trans is burnt & unuseable
    It will have to be rebuilt
    Never flush a trans unless you want
    I have no Idea how there could be any discussion
    about a burn trans. It was run into the ground & the
    fluid never changed. You don't have to get fluid out
    of a converter. As was said. When it is burnt or slips
    it will slip worst. You would think after 70 years people
    would understand auto tranjs fluid

2000 Grand Prix GT with a code of P1860. What is this code and how do I fix it?

P1860 refers to Torque converter clutch problem, what I mean is that when you go to O/D over drive the torque converter does not lock. You may have to take the vehicle into a ****** shop and they will change the modulator. Good luck and let me posted.

Code scanner says torque converter circiut stuck on. 1998 Grand Prix

The code scanner is indicating that the TCC or Torque Converter Circuit (Clutch) Solenoid is on all of the time. The TCC solenoid must be replaced to fix this problem which requires taking a pan off and replacing a spaghetti-like wired contraption known to go bad that is a solenoid that controls the TCC.

Grand prix torque converter locks up too soon

Either the speed sensor, TCC solenoid , ECU or a stuck check ball in a lockup plate. I recommend taking this to a transmission shop this could get fustrating.

How to change a torque converter

You have to remove either the engine or transmission, whichever's easier. Front wheel drives are usually easier to remove the transmission, which will require removing both CV shafts, brakes, hubs, and struts. You then unbolt the transmission from the engine, slide it back a little, unbolt the torque converter from the flywheel, and drop the transmission out of the bottom of the car, and then you can pull the torque converter off the transmission and replace it.

1998 Pontiac Grand Prix shuts down in Drive or Reverse

When you remove your vehicle from park, the idle air control valve (electronic choke) operates to keep enough air going into the motor while you aren't using the throttle so it will stay running. If it is too dirty it can't move'll stall.
Pull out and clean or replace the idle air control valve.
