    I'm looking into putting in a stall converter in my 95 SHO ATX ,It's been sitting for over 2yrs cause it needs a trans .I'm getting the tranny rebuilt but I wanna know if putting a stall converter in will improve performance ? as far as shifting

    all converters "stall" it just depends on the rpm at which that occurs.

    imho, the factory converter has a very good match to the engine. if you put in one that has a lower stall rpm, then it might do a little better on gas but performance would be reduced due to lower torque at lower rpms. if you put in a tc that has a higher stall rpm, then mileage will be reduced and the engine will be revving up all the time - I think that would get tiring to drive, but that is just my opinion.

    well I was on shosource and they had different ones from :

    street revs: 2200-2400 RPM stall

    Junior Revs: 2600-2800 RPM stall

    High Revs: (option for no lock up clutch) 3000-3400 RPM stall

    High Revs Race: (no lock up) 3600-3800 RPM stall

    they said the stock stall for the ATX is 2400 RPM but I was thinking about the junior rev stall

    I always thought the stock tc was around 2400-2600 stall. Or maybe they just got that way by the time they had a bunch of miles on them. Anyway, I would not go higher than 2800 for a street / daily driver type vehicle. And for sure you want a lock up clutch if you drive it on the street or highway.

    The original converter in the SHO is about as good as it gets, and is already a higher stall rpm unit. There are many nice things you can do the automatic to give you a much better driving experience, but I would leave the converter alone.

    for starters:
    1. all the maintenance that prior owners neglected.
    2. better brakes, at least on the front.
    3. larger rear sway bar.
