So the manual 1354 is in and working. Mostly...
1st question
I've read here or at ExplorerForum about how to wire the 4WD and 4LOW lights on the dash using the 2 wires from the manual case. But I'd really like to know how to tell the 4R55E when the T-case is in low range. As it is, in low range the transmission won't shift past 2nd gear because the speed is low and it doesn't know that 4low is engaged. Any ideas?
2nd question
EDIT TO REVISE - a bit of operator error on my part. When testing the manual case last night, I was driving on pavement, so had my manual hubs unlocked. Shifting from 2 high to 4 high while driving would be expected to not work right, since the front driveshaft wasn't turning. So question 2 is just this: When shifting between 4low and 4high (manual T-case, auto transmission), what's recommended? Seems like the tranny output shaft will begin turning as the T-case goes through neutral and some grinding would be unavoidable. I've always had manual trans with manual t-cases before this.
Ignore the previous question below...
Does a 1354 have synchronizers that could wear out? When shifting between high and low range (full stop, tranny in neutral), I'm getting a fair amount of grinding if I try to ease the T-case into gear. It will go if I just bang it in, but seems a bit abusive. Also noticed that 'shift on the fly' between 2hi and 4hi doesn't seem to lock in immediately as it should. If I stop, it locks in right away.
I did come across another manual 1354 at the junkyard this weekend - I'm wondering if I'm going to need it.
