I bought an 89 Comanche 4.0 2wd that originally had a five speed Peugeot transmission. The five-speed Peugeot transmission that came with it doesn’t work it’s shot because those Peugeot transmissions kind of sucked but it came with an extra transmission that is a four-speed manual and I have no idea what it is. Whenever we did the transmission swap the bolt pattern lines up perfectly and shifter works good everything works fine except for the fact that it has a 27 spline output shaft where as the Peugeot had a 21 spline output shaft. The problem I’m having is I don’t know what transmission this new one is so it’s making it almost impossible to find the correct part without taking it to an actual transmission shop a cost that I’m not ready to pay. If anybody knows what other transmissions outside of AX5 or AX 15 may have been used in these Comanches or works in them please let me know I don’t think it’s an NV 3550 and I know it’s not an X5 or an AX 15 could be an AX4 but I’ve never seen one before so I wouldn’t know. Some jerk filed off the serial number from the new transmission and the part number so I can’t even look at that to know what it is
