    I'm trying to find a four speed auto for my 56 Chev convertible. I'm told that a 200R4 has the same overall length as my powerglide. A buddy has this trans available and I don't know enough about them to ID it. Check it out and see if it's what I need.....thanks!

    It's a late TH700R4/4L60 with an auxiliary valve body. And electric speedo.

    I know I have another one about ID ing by pan gasket shapes, but I can't seem to find it quickly right now.
    Your pic does have a 700r4 look like the one in my Stude, but I built mine 20+ yrs ago, so I am using old memory :)

    WHY BE ORDINARY ?

    you don't need a chart to see that it's a 700, do you ?

    I always find the 'transmission ID' charts that use pan gaskets could always be more informative. They often don't show the orientation in the vehicle, they don't specify whether you are looking up or down at the unit and are reproduced at varying sizes mixed together.

    Yes Jim, I DO need help ID-ing any automatic. Driven manual four speeds most of my life.
    Thanks gents, for all the quick responses and charts. A great help.
    Any idea as to value?

    $150-400USD depending on condition.

    Working at a junkyard for a while should be a prerequisite for building hot rods

    Now any of you wise guys know if there's anyway that trans would fit in my 56 chev ragtop with the X braced frame? Does it need a computer to run it? and I thought there was a way to hook up the mechanical speedo instead of the electric? I know the 200r4 is the same length as my powerslide but I'm not sure about the 700r4 swap.
    Thanks in advance.

    Neither a 700R4 or a 2004R require a computer. They do require a 12+ IGN wire, if you'd like the torque converter to lock up in high gear. Both can have mechanical speedometer drives.

    Neither is the same length as a Powerglide, although, if you have the longer aluminum Powerglide, a 2000R4 is pretty close.

    The "X" looks like it is largely behind where the body of the transmission is:

    Thanks for the info.....very helpful. I guess I'll pass by the Tri-five forum and see what's up with the swap. cheers.

    heh...nope! and I quit working at the junkyard in 1982, just after the 700 came out. I saw my first one at the transmission shop, where I worked next. They had trouble with them from the beginning.
