C4 In Park But Still Rolls Back And Forth

[broncosport]

I have a fairly new (reman) C4 from CHECKERS Auto parts, never had any problems with it, untill now! My problem is when its in PARK it will still roll back and forth??? So whats up???

Does it roll like it's in neutral or just a few inches? Mine has always moved a few inches back & forth.

Adjust the linkage.

Adjust the linkage, put the transfer case in gear, if it still hits the pawl and stops then a few inches of backlash in the drivetrain is normal.

Now if you did really loose park then it's time to take it apart and look inside. It has been many years since I have been in one of those old 3 speeds, but look the mechanism over and see what isn't working. I think you can deal with most of the parking parts without actually having to gut the trans. Again been many years...

Its not backlash. It rolls like its in neutral. I've already adjusted the linkage to the extream in both directions but it still rolls! Its cable actuated (B&M Mega shifter), Anything else I can check/adjust??

i could be waaaay off here, so don't flog me:
could your detent plate be worn, thus letting the vehicle slip from park? (i don't know if that's possible with the BM mega shifter, so like i said, don't flog me for being an idiot! ;D )

if so, though, this could help: http://classicbroncos.com/forums/showthread.php?t=108289

Make sure to check your shifter linkage in the truck. I run the Hurst cable operated and a nut that holds the cable to the shifter came loose on me (I could only tell once I had stopped and came back out to leave).

Sounds like a broken parking pawl. Read this thread about repairing it.

Like Broncobowsher said the only way to really see what is happening is perhaps pull the valve body, most C-4 park problems can be cured with removal of TC and VB, and a complete disassembly may not be required unless the tip of the pawl is broke off.
