Automatic or manual? The '88 was an American Motors product that used a Chrysler automatic transmission. The '93 is a Chrysler product with the same transmission, but they used different engines. The flex plates are different most likely because the crankshaft flanges are different, but the torque converter mounts could be different too. Of most concern would be the bolt pattern on the back of the engine block. In the '70s Chrysler cast special transmission housings for AMC. AMC did not design their engines to match Chrysler transmissions, so while the internal parts and rebuild kits were the same for both products, the housings were not interchangeable. My guess is the same holds true in your case, but to be sure there's two things you can do. One is to visit any salvage yard and ask. They will have a Hollander Interchange Guide that will list both applications and show if the same part fits the applications. The other choice is to visit the Chrysler dealer's parts department and have them look up the part numbers for both applications to see if they're the same. Even if they are, there will be differences in external parts that will likely require you to remove some things from your old transmission and put them on the replacement.
