They're cheaper here with bad motors, cost just as much as all the 4.0 Jeeps with bad motors. Not always cheaper than bad motor Magnum trucks though since Magnum replacements are so readily available and... good.
Most of the stock 4.7 Jeeps were fairly close to the 5.9s, the 4.7HOs IIRC were a shade faster. Doesn't mean I wouldn't take a 5.9 everyday of the week and twice on Sunday over a 4.7 but they aren't awful.
Well the last '96 I saw I never bothered to get under it since the data tag called out the 32RH. That's why I'll believe them. But yes, that's my experience- if it's anything RWD-based but a van or TJ it will have an overdrive but with vans they could have 3spds as well as the ODs.
Yes. One of the biggest ones is the high cost of most motors.
