    Even after all these years of hearing about switch pitch transmissions I had never seen the parts laid out.

    Thanks for the pictures.

    Curious about two things.
    1. Does the pump need the drum and input shaft to work?
    2. What is the stall difference from stock. Meaning when you switch the pitch.
    Thanks
    PJ

    It needs the shaft, but the drum is standard TH400.
    Stall difference depends on which converter (12" or 13") and engine torque. Can't remember the stock specs but its posted elsewhere on the site. Somewhere around 1000 rpm diff. for the 13" and maybe 1500 for the 12" in stock applications? The 13" starts lower than the 12" too. They can be modified for different stall speeds as well.

    Some claim different, but several 12" V-P convertors that I've had, or been involved with went 2000 in low, 3000 in high. Anything from 3000 lbs to 3600 lb cars. I believe that when the "rebuilders" re-do them, they somehow screw them up. A friend had a rebuilt 12" [recon] that would only go 2400 in high. He put a junkyard 12" in, bingo = 3000 stall.

    Two 13" that i've had were 1000 in low, 2500 in high.

    As HD wrote, you need the input shaft, easiest to just use the shaft and drum from the donor trans. You need the pump, solenoid on pump, two prong wire terminal for case [still sold, was used later for "smog" wiring].

    ***** you need the resricting orifice cup from the case of the donor trans. It's in a passage behind the pump flange at apx 8 O'clock, looking at the case. You can fashion one from a glass fuse. Can't remember orifice size at the moment......

    ***** You need [easiest, anyway] an 8 BOLT CASE. The 6 bolt cases do not have the plumbing req'd. Afaik, Bruce [member here] may know how to make them work in a 6 bolt case.

    Someone should get this stuff. Shame for it to go to scrap.

    Btw, I'm not sure that Jim Weise is doing them any more. Tri-Shield might be, but imo, they should be avoided.

    Ok. Thank you both... very good info. Ill find more here on the forum. I think i remember reading something about it. Dave did you use some quotes from the forum you posted above? I remember reading something about the fuse ends i thing someone was trying to convert on but something didnt match or couldnt work. Maybe a eldo front wheel drive. Idk.
    Thank for the info. Ill find more on here.

    Are these parts still available? I am interested in the sp pump, input shaft, and the 12" ST300 converter.

    If Jim doesn't do them anymore and Tri-Shield isn't a good choice, is there a recommended shop that can rebuild a VP converter for "like new" or better durability?
