Silver Sport A41 4speed auto
A500 42RH or A518 46RH. A little fab work to bolt in. All over the junkyards. Has a 3 speed pattern with O/D pushbutton lockup. Chrysler designed offshoot of the torqueflight A904-A727. Rebuild kits readily available. Has a .7 O/D. A500 has a numerically lower first gear that the A518. Can be built to handle a decent amount of HP. Way cheaper buy in price. Factory Chrysler part. Lokar and summit both make a push pull kickdown cable arrangement for it. If you already have an aftermarket A904 -A727 shifter, it will direct fit the Chrysler O/D. I will pass on the A41
