    Any benefits of using one of these or are they exactly the same as non police/taxi 727's? I have one in my recently acquired D100's that is pulled out and ready for rebuilding and just thought someone might know if any components are different/better??

    Thanks,
    Jake

    what year? the service manual should have that info. think they had a better clutch pack, so there's nothing you can't upgrade on a rebuild

    I would agree...if anything it would have been better internals but after 50 years it could have been rebuilt once or twice already so who knows what is in it.....You can rebuild it any way you want

      When I worked in the industry, one of my customers had a contract to do transmissions for the largest cab company in the City. The cabs were a real mixture of x-cop cars, and anything that was cheap to buy(typical at the time of the taxi industry). As I recall, any city cop car transmissions were nothing special(typical 318 configuration), but if he got any pursuit cars to repair that was another thing. A 440 powered pursuit car had almost the same stuff as the Hemi transmission. Solid bands, extra clutches in the drums, better planets, etc. I don't know what the taxi industry is like in your area, but based on my experience and taxi transmissions, cheap was the by word. Also, bbrroowwnn nailed it with that after 50 years of service, used and abused in the taxi and police fleets, it's been probably built a number of times.

        Thanks for the info guys, just wondered if I was going to run into anything different. I’m just doing a stock rebuild for stock 360 1/2 ton d100.

        Just a thought, There might have been some differences in the valve body timing, pressure etc.

          Well, I got into it and it looked really good until I got to the clutch pack and the steels and clutches are really warped, I’m assuming that’s why it started strong then slipped really bad. Any thoughts?

          Jake it's been some time, and the memories get a bit fuzzy now and then, but I seem to recall that we sold an aftermarket steel wave plate. I believe it had something to do with cushioning how the clutch pack applied. There's a couple of pro builders on this thread that can maybe clear this up for sure. I notice that there is only one steel plate that is waved out of the clutch pack you're showing. This makes me think that it is an aftermarket wave steel. However, you say steels and the clutches are warped, if so, then excessive heat would cause both types of plates to warp.

            The wave snap ring is for the front clutch drum. Yes, excessive heat/ slippage caused the clutches and steels to warp. Kim
