    I know one of the biggest killers of the 700 is heat. I have a factory tranny cooler and am going to be installing an additional unit inline soon. But, I was also looking at replacing the pan with a larger, finned one with a drain plug. Seems to me the greater capacity, finned design would help keep the oil cooler. Is there a chance of keeping it too cool?

    has anyone done this? Where did you get yours? How much?

    I got mine from Jeg's. Its a TCI automative pan.
    2 extra quarts, drain plug, aluminum with fins. Comes with bolts that are too short. I replaced them at HOme depot.
    The only problem with it is that the dust shield that covers the torque convertor has to be taken off and trimmed up a bit so the new pan can fit. Also I had a problem getting the pan on because the exhaust pipe (collector) runs right under where my pan goes. I had to jack the tranny up as high as it would go and pull down on the collector pipe and still had to wedge it in there. But it was too bad.
    It was about $110 bones.

    same pan as ftn96 a TCI Aluminum with fins and drain, have to go the same route grinding for clearance but its a decent price I got mine at Summit for about the same, but so far a small bit of one fin broke. BUt its great otherwise.

    I have used the TCI pan also and had to do alittle fin grinding to clear the cross-over pipe on 90Blazer stock exhaust. Other than that its a decent pan and I removed it before selling the rig a few years ago and still have it, like the others said two extra gts. with drain plug.
    My 700 was getting hot on long hills and spewing fluid from the thin gasket area along the front side of the pan, I added a big cooler,TCI pan and gage all at the same time and it never did it again and would run around 160 d. normal driving and 180-190 working hard.
    I dont think that you could get a 700 to cool if you have not by-passed the radiator cooler, I by-passed mine and ran it in the winter without any problem other than a harsh shift until it warmed up!

    I dont have any plans for using a 700 at this time and could probably sell the pan for $75. shipped if you want to safe a couple bucks but will need to get a gasket, the mods
    already been done too.
