Welcome. One stutter up a grade could be associated with the converter lockup disengaging. I would infrequently get a momentary chuggle up a grade until the tranny remembered to kick out. If your ABS/TC fault is intermittent then do your testing with someone else wiggling the wires. The rears take a lot of abuse from debris/elements. Running staggereds with too large a delta will cause ABS to fault.
[QUOTE: Will the front ABS sensors work in the back 3.73 w/disk brakes differential?]
Wording not clear.
If this rear is the original one or came out of another FWB then we're still fine. If this rear is from a B- body then it won't work. The latter may be a different width than the Cady's, and it will only have the 3-channel style ABS reluctor in the pinion - not the ones at each wheel.
1.So, you're trying to install some spare new front sensors you have into the rear? Answer: IDK. But you may need to mod the backing plates for orienting the mounts.
2.You're asking about whether the Bosch 4-channel system would care what gears the car has? Answer: I don't see why it matters. Tow Package FWBs get 3.46 and 3.73 is not that different.
